Take Five for Dave Brubeck

Innovative Jazz pianist Dave Brubeck has died, one day shy of his 92nd birthday.

Though the melody of Take Five, arguably his most famous recording (featured above), is credited to his quartet’s saxophonist, Paul Desmond, it is Brubeck’s love of uncommon time signatures that lays the foundation for one of the most iconic musical works of the 20th Century.

But Brubeck wasn’t just a crusader for rhythm. During his service in World War II, Brubeck was spotted playing a Red Cross show and ordered to form a band. Brubeck chose a racially integrated lineup, a rarity for military acts. During the 1950s and ’60s, Brubeck is reported to have canceled appearances at venues that balked at the mixed racial makeup of his quartet.

Brubeck was also said to have been upset when he was featured on the cover of Time magazine in 1954 (only the second Jazz musician so honored), believing that the selection was influenced by race.

Though he disbanded the quartet in 1967, Brubeck continued to compose and perform into his 90s. He was the recipient of numerous accolades and awards, including a Kennedy Center honor and a Grammy for lifetime achievement.

LIPA’s Nuclear Legacy Leaves Sandy’s Survivors in the Dark

Head of Long Island Power Authority Steps Aside as Governor Convenes Special Commission, But Problems Have Deep Roots

As the sun set on Veterans Day, 2012, tens of thousands of homes on New York’s Long Island prepared to spend another night in darkness. The lack of light was not part of any particular memorial or observance; instead, it was the noisome and needless culmination of decades of mismanagement and malfeasance by a power company still struggling to pay for a now-moldering nuclear plant that never provided a single usable kilowatt to the region’s utility customers.

The enterprise in charge of all that darkness bears little resemblance to the sorts of power companies that provide electricity to most Americans–it is not a private energy conglomerate, nor is it really a state- or municipality-owned public utility–but the pain and frustration felt by Long Island residents should be familiar to many. And the tale of how an agency mandated by law to provide “a safer, more efficient, reliable and economical supply of electric energy” failed to deliver any of that is at its very least cautionary, and can likely serve as an object lesson for the entire country.

Almost immediately, the United States will be faced with tough choices about how to create and deliver electrical power. Those choices are defined not just by demand but by a warming climate and an infrastructure already threatened by the changes that climate brings. When one choice, made by a private concern nearly 50 years ago, means weeks of power outages and billions of dollars in repair costs today, it suggests new decisions about America’s energy strategy should be handled with care.

A stormy history

Two weeks after Hurricane-cum-Superstorm Sandy battered the eastern coast of the United States, upwards of 76,000 customers of the Long Island Power Authority (LIPA) were still without power. That number is down markedly from the one million LIPA customers (91 percent of LIPA’s total customer base) that lost power as Sandy’s fierce winds, heavy rains and massive storm surge came up the Atlantic Coast on Monday, October 29, and down, too, from the over 300,000 still without service on election day, but at each step of the process, consumers and outside observers alike agreed it was too many waiting too long.

And paying too much. LIPA customers suffer some of the highest utility rates in the country, and yet, the power outages that came with last month’s storm–and a subsequent snowstorm nine days later–while disgraceful, were far from unexpected. The Long Island Power Authority and its corporate predecessor, the Long Island Lighting Company (LILCO), have a long track record of service failures and glacial disaster response times dating back to Hurricane Gloria, which hit the region in the autumn of 1985.

After Gloria, when many Long Island homes lost power for two weeks, and again after widespread outages resulted from 2011’s Hurricane Irene, the companies responsible for providing electricity to the residents of most of Nassau and Suffolk Counties, along with parts of the Borough of Queens in New York City, were told to make infrastructure improvements. In 2006, it was reported that LIPA had pledged $20 million annually in grid improvements. But the reality proved to be substantially less–around $12.5 million–while LIPA also cut back on transmission line inspections.

Amidst the current turmoil, New York Governor Andrew Cuomo has been highly critical of LIPA, calling for the “removal of management” for the “colossal misjudgments” that led to the utility’s failures. Cuomo made similar statements about LIPA and its private, for-profit subcontractor, National Grid, last year after Hurricane Irene. But as another day mercifully dawned on tens of thousands of homes still without electricity over two weeks after Sandy moved inland, the dysfunctional structure in charge of the dysfunctional infrastructure remains largely unchanged.

Which, it must be noted, is especially vexing because Governor Cuomo should not be powerless when it came to making changes to the Long Island Power Authority.

It was Andrew’s father, Governor Mario Cuomo, who oversaw the creation of LIPA in 1985 to clean up the fiscal and physical failures of the Long Island Lighting Company. LILCO’s inability to quickly restore power to hundreds of thousands of customers after Hurricane Gloria met with calls for change quite similar to contemporary outrage. But it was LILCO’s crushing debt that perhaps exacerbated problems with post-Gloria cleanup and absolutely precipitated the government takeover.

The best-laid schemes

It was April 1965 when LILCO’s president announced plans for Long Island’s first commercial nuclear power facility to be built on Long Island Sound near the town of Brookhaven, already home to a complex of research reactors. The 540-megawatt General Electric boiling water reactor (similar in design to those that failed last year in Japan) was estimated to cost $65 million and come online in 1973.

The price of the Shoreham nuclear project quickly ballooned, first, as LILCO proposed additional reactors across Long Island–none of which were ever built–and then as the utility up-rated the original design to 820 megawatts. Further design changes, some mandated by the Nuclear Regulatory Commission, and construction delays pushed the price tag to $2 billion by the late 1970s.

Because of its proximity to the Brookhaven reactors, LILCO expected little public activism against Shoreham, but local opposition steadily grew throughout the ’70s. The Sierra Club, the Audubon Society and environmentalist Barry Commoner all raised early objections. After a meltdown at Pennsylvania’s Three Mile Island nuclear plant in 1979, Shoreham saw 15,000 gather in protest outside its gates, an action that resulted in 600 arrests.

Three Mile Island led to new NRC rules requiring nuclear facilities to coordinate with civic authorities on emergency plans for accidents necessitating the evacuation of surrounding communities. LILCO was forced to confront the fact that, for Shoreham, the only routes for evacuation were already clogged highways that bottlenecked at a few bridges into Manhattan, 60 miles to the west.

In 1983, the government of Suffolk County, where Shoreham was located, determined that there was no valid plan for evacuating its population. New York Governor Mario Cuomo followed suit, ordering state regulators not to approve the LILCO-endorsed evacuation plan.

Still, as Shoreham’s reactor was finally completed in 1984, 11 years late and nearly 100-times over budget, the NRC granted LILCO permission for a low-power test.

But 1985’s Hurricane Gloria further eroded trust in LILCO, and the next year, the Chernobyl disaster further galvanized opposition to a nuclear plant. As LILCO’s debts mounted, it became apparent that a new structure was needed to deliver dependable power to Long Island residents.

The power to act

The Long Island Power Act of 1985 created LIPA to assume LILCO’s assets, and a subsidiary of this municipal authority, also known as LIPA, acquired LILCO’s electric transmission and distribution systems a year later. The radioactive but moribund Shoreham plant was purchased by the state for one dollar, and later decommissioned at a cost of $186 million. (Shoreham’s turbines were sent to Ohio’s Davis-Besse nuclear facility; its nuclear fuel was sent to the Limerick Nuclear Power Plant, with LILCO/LIPA paying Philadelphia Electric Company $50 million to take the fuel off its hands.)

The $6 billion Shoreham folly was passed on to consumers in the form of a three-percent surcharge on utility bills, to be charged for 30 years. Service on LILCO’s $7 billion in debt, half of which is a direct result of Shoreham, makes up 16 percent of every LIPA bill.

But LIPA itself is not really a utility company. Its roughly 100 employees are low on public utilities experience and, as the New York Times reports, high on political patronage. The majority of LILCO’s non-nuclear power plants were sold to a newly created company called KeySpan (itself a product of a merger of LILCO holdings with Brooklyn Union Gas), and maintenance of LIPA’s grid was subcontracted to KeySpan.

KeySpan was in turn purchased by British power company National Grid in 2006.

The situation is now further complicated, as National Grid lost out to Public Service Enterprise Group, New Jersey’s largest electricity provider, in a bid to continue its maintenance contract. PSEG takes over the upkeep of LIPA’s grid in 2014.

A commission on transmission

On Tuesday, Governor Cuomo the Younger announced formation of a Moreland Commission–a century-old New York State provision that allows for an investigative body with subpoena power–to explore ways of reforming or restructuring LIPA, including the possibility of integrating with the state’s New York Power Authority. And just hours later, LIPA’s COO and acting CEO, Michael Hervey, announced he would leave the utility at the end of the year.

But the problems look more systemic than one ouster or one commission, no matter how august, can correct. Andrew Cuomo’s inability to appoint new LIPA board members could owe as much to entrenched patronage practices as to political pre-positioning. State Republicans, overwhelmingly the beneficiaries of LIPA posts, are engaged in a behind-the-scenes standoff with the Democratic Governor over whom to name as a permanent LIPA director. Others see Cuomo as too willing to accept the political cover conveyed by not having his appointees take control of the LIPA board.

Still, no matter who runs LIPA, the elaborate public-private Russian-doll management structure makes accountability, not to mention real progress, hard to fathom. Perhaps it would be crazy to expect anything but regular disasters from a grid maintained by a foreign-owned, lame-duck, for-profit corporation under the theoretical direction of a leaderless board of political appointees, funded by some of the highest electricity rates in the country. And those rates, by the way, are not subject to the same public utilities commission oversight that would regulate a private utility, nor do they seem sensitive to any democratic checks and balances.

And all of this was created to bail out a utility destabilized by the money pit that is nuclear power.

The truth has consequences

As nighttime temperatures dip below freezing, it will be cold comfort, indeed, for those still without the power to light or heat their homes to learn that money they have personally contributed to help LIPA with its nuclear debt could have instead paid for the burying of vulnerable transmission lines and the storm-proofing of electrical transformers. But the unfortunate results of that trade-off hold a message for the entire country.

It was true (if not obvious) in 1965, it was true in 1985, and it is still true today: nuclear power, beyond being dirty and dangerous, is an absurdly expensive way to generate electricity. This is especially apropos now, in the wake of a superstorm thought to be a harbinger of things to come as the climate continues to warm.

In recent years, the nuclear industry has latched on to global warming as its latest raison d’être, claiming, quite inaccurately, that nuclear is a low-greenhouse gas answer to growing electrical needs. While the entire lifecycle of nuclear power is decidedly not climate friendly, it is perhaps equally as important to consider that nuclear plants take too long and cost too much to build. The time, as well as the federal and consumer dollars, would be better spent on efficiency, conservation, and truly renewable, truly climate-neutral energy projects.

That is not a hypothetical; that is the lesson of LIPA, and the unfortunate reality–still–for far too many New York residents.

Oyster Creek Nuclear Alert: As Floodwaters Fall, More Questions Arise

New Jersey’s Oyster Creek Nuclear Generating Station remains under an official Alert, a day-and-a-half after the US Nuclear Regulatory Commission declared the emergency classification due to flooding triggered by Hurricane Sandy. An Alert is the second category on the NRC’s four-point emergency scale. Neil Sheehan, a spokesman for the federal regulator, said that floodwaters around the plant’s water intake structure had receded to 5.7 feet at 2:15 PM EDT Tuesday, down from a high of 7.4 feet reached just after midnight.

Water above 6.5 to 7 feet was expected to compromise Oyster Creek’s capacity to cool its reactor and spent fuel pool, according to the NRC. An “Unusual Event,” the first level of emergency classification, was declared Monday afternoon when floodwaters climbed to 4.7 feet.

Though an emergency pump was brought in when water rose above 6.5 feet late Monday, the NRC and plant owner Exelon have been vague about whether it was needed. As of this writing, it is still not clear if Oyster Creek’s heat transfer system is functioning as designed.

As flooding continued and water intake pumps were threatened, plant operators also floated the idea that water levels in the spent fuel pool could be maintained with fire hoses. Outside observers, such as nuclear consultant Arnie Gundersen, suspected Oyster Creek might have accomplished this by repurposing its fire suppression system (and Reuters later reported the same), though, again, neither Exelon nor regulators have given details.

Whether the original intake system or some sort of contingency is being used, it appears the pumps are being powered by backup diesel generators. Oyster Creek, like the vast majority of southern New Jersey, lost grid power as Sandy moved inland Monday night. In the even of a site blackout, backup generators are required to provide power to cooling systems for the reactor–there is no such mandate, however, for spent fuel pools. Power for pool cooling is expected to come either from the grid or the electricity generated by the plant’s own turbines.

As the NRC likes to remind anyone who will listen, Oyster Creek’s reactor was offline for fueling and maintenance. What regulators don’t add, however, is that the reactor still needs cooling for residual decay heat, and that the fuel pool likely contains more fuel and hotter fuel as a result of this procedure, which means it is even more at risk for overheating. And, perhaps most notably, with the reactor shutdown, it is not producing the electricity that could be used to keep water circulating through the spent fuel pool.

If that sounds confusing, it is probably not by accident. Requests for more and more specific information (most notably by the nuclear watchdog site SimplyInfo) from Exelon and the NRC remain largely unanswered.

Oyster Creek was not the only nuclear power plant dealing with Sandy-related emergencies. As reported here yesterday, Nine Mile Point Unit 1 and Indian Point Unit 3–both in New York–each had to scram because of grid interruptions triggered by Monday’s superstorm. In addition, one of New Jersey’s Salem reactors shut down when four of six condenser circulators (water pumps that aid in heat transfer) failed “due to a combination of high river level and detritus from Hurricane Sandy’s transit.” Salem vented vapor from what are considered non-nuclear systems, though as noted often, that does not mean it is completely free of radioactive components. (Salem’s other reactor was offline for refueling.)

Limerick (PA) reactors 1 and 2, Millstone (CT) 3, and Vermont Yankee all reduced power output in response to Superstorm Sandy. The storm also caused large numbers of emergency warning sirens around both Oyster Creek and the Peach Bottom (PA) nuclear plant to fail.

If you thought all of these problems would cause nuclear industry representatives to lay low for a while, well, you’d be wrong:

“Our facilities’ ability to weather the strongest Atlantic tropical storm on record is due to rigorous precautions taken in advance of the storm,” Marvin Fertel, chief executive officer of the Nuclear Energy Institute, a Washington-based industry group, said yesterday in a statement.

Fertel went on to brag that of the 34 reactors it said were in Sandy’s path, 24 survived the storm without incident.

Or, to look at it another way, during a single day, the heavily populated eastern coast of the Unite States saw multiple nuclear reactors experience problems. And that’s in the estimation of the nuclear industry’s top lobbyist.

Or, should we say, the underestimation? Of the ten reactors not in Fertel’s group of 24, seven were already offline, and the industry is not counting them. So, by Fertel’s math, Oyster Creek does not figure against what he considers success. Power reductions and failed emergency warning systems are also not factored in, it appears.

This storm–and the trouble it caused for America’s nuclear fleet–comes in the context of an 18-month battle to improve nuclear plant safety in the wake of the multiple meltdowns and continuing crisis at Japan’s Fukushima Daiichi nuclear facility. Many of the rules and safety upgrades proposed by a US post-Fukushima taskforce are directly applicable to problems resulting from Superstorm Sandy. Improvements to flood preparation, backup power regimes, spent fuel storage and emergency notification were all part of the taskforce report–all of which were theoretically accepted by the Nuclear Regulatory Commission. But nuclear industry pushback, and stonewalling, politicking and outright defiance by pro-industry commissioners has severely slowed the execution of post-Fukushima lessons learned.

The acolytes of atom-splitting will no doubt point to the unprecedented nature of this massive hybrid storm, echoing the “who could have predicted” language heard from so many after the earthquake and tsunami that started the Fukushima disaster. Indeed, such language has already been used–though, granted, in a non-nuclear context–by Con Edison officials discussing massive power outages still afflicting New York City:

At a Consolidated Edison substation in Manhattan’s East Village, a gigantic wall of water defied elaborate planning and expectations, swamped underground electrical equipment, and left about 250,000 lower Manhattan customers without power.

Last year, the surge from Hurricane Irene reached 9.5 feet at the substation. ConEd figured it had that covered.

The utility also figured the infrastructure could handle a repeat of the highest surge on record for the area — 11 feet during a hurricane in 1821, according to the National Weather Service. After all, the substation was designed to withstand a surge of 12.5 feet.

With all the planning, and all the predictions, planning big was not big enough. Sandy went bigger — a surge of 14 feet.

“Nobody predicted it would be that high,” said ConEd spokesman Allan Drury.

In a decade that has seen most of the warmest years on record and some of the era’s worst storms, there needs to be some limit on such excuses. Nearly a million New York City residents (including this reporter) are expected to be without electricity through the end of the week. Residents in the outer boroughs and millions in New Jersey could be in the dark for far longer. Having a grid that simply survives a category 1 hurricane without a Fukushima-sized nuclear disaster is nothing to crow about.

The astronomical cost of restoring power to millions of consumers is real, as is the potential danger still posed by a number of crippled nuclear power plants. The price of preventing the current storm-related emergencies from getting worse is also not a trivial matter, nor are the radioactive isotopes vented with every emergency reactor scram. All of that should be part of the nuclear industry’s report card; all of that should raise eyebrows and questions the next time nuclear is touted as a clean, safe, affordable energy source for a climate change-challenged world.

UPDATE: The AP is reporting that the NRC has now lifted the emergency alert at Oyster Creek.

Superstorm Sandy Shows Nuclear Plants Who’s Boss

Once there was an ocean liner; its builders said it was unsinkable. Nature had other ideas.

On Monday evening, as Hurricane Sandy was becoming Post-Tropical Cyclone Sandy, pushing record amounts of water on to Atlantic shores from the Carolinas to Connecticut, the Nuclear Regulatory Commission issued a statement. Oyster Creek, the nation’s oldest operating nuclear reactor, was under an Alert. . . and under a good deal of water.

An Alert is the second rung on the NRC’s four-point emergency classification scale. It indicates “events are in process or have occurred which involve an actual or potential substantial degradation in the level of safety of the plant.” (By way of reference, the fourth level–a General Emergency–indicates substantial core damage and a potential loss of containment.)

As reported earlier, Oyster Creek’s coolant intake structure was surrounded by floodwaters that arrived with Sandy. Oyster Creek’s 47-year-old design requires massive amounts of external water that must be actively pumped through the plant to keep it cool. Even when the reactor is offline, as was the case on Monday, water must circulate through the spent fuel pools to keep them from overheating, risking fire and airborne radioactive contamination.

With the reactor shut down, the facility is dependant on external power to keep water circulating. But even if the grid holds up, rising waters could trigger a troubling scenario:

The water level was more than six feet above normal. At seven feet, the plant would lose the ability to cool its spent fuel pool in the normal fashion, according to Neil Sheehan, a spokesman for the Nuclear Regulatory Commission.

The plant would probably have to switch to using fire hoses to pump in extra water to make up for evaporation, Mr. Sheehan said, because it could no longer pull water out of Barnegat Bay and circulate it through a heat exchanger, to cool the water in the pool.

If hoses desperately pouring water on endangered spent fuel pools remind you of Fukushima, it should. Oyster Creek is the same model of GE boiling water reactor that failed so catastrophically in Japan.

The NRC press release (PDF) made a point–echoed in most traditional media reports–of noting that Oyster Creek’s reactor was shut down, as if to indicate that this made the situation less urgent. While not having to scram a hot reactor is usually a plus, this fact does little to lessen the potential problem here. As nuclear engineer Arnie Gundersen told Democracy Now! before the Alert was declared:

[Oyster Creek is] in a refueling outage. That means that all the nuclear fuel is not in the nuclear reactor, but it’s over in the spent fuel pool. And in that condition, there’s no backup power for the spent fuel pools. So, if Oyster Creek were to lose its offsite power—and, frankly, that’s really likely—there would be no way cool that nuclear fuel that’s in the fuel pool until they get the power reestablished. Nuclear fuel pools don’t have to be cooled by diesels per the old Nuclear Regulatory Commission regulations.

A site blackout (SBO) or a loss of coolant issue at Oyster Creek puts all of the nuclear fuel and high-level radioactive waste at risk. The plant being offline does not change that, though it does, in this case, increase the risk of an SBO.

But in the statement from the NRC, there was also another point they wanted to underscore (or one could even say “brag on”): “As of 9 p.m. EDT Monday, no plants had to shut down as a result of the storm.”

If only regulators had held on to that release just one more minute. . . .

SCRIBA, NY – On October 29 at 9 p.m., Nine Mile Point Unit 1 experienced an automatic reactor shutdown.

The shutdown was caused by an electrical grid disturbance that caused the unit’s output breakers to open. When the unit’s electrical output breakers open, there is nowhere to “push” or transmit the power and the unit is appropriately designed to shut down under these conditions.

“Our preliminary investigation identified a lighting pole in the Scriba switchyard that had fallen onto an electrical component. This is believed to have caused the grid disturbance. We continue to evaluate conditions in the switchyard,” said Jill Lyon, company spokesperson.

Nine Mile Point Nuclear Station consists of two GE boiling water reactors, one of which would be the oldest operating in the US were it not for Oyster Creek. They are located just outside Oswego, NY, on the shores of Lake Ontario. Just one week ago, Unit 1–the older reactor–declared an “unusual event” as the result of a fire in an electrical panel. Then, on Monday, the reactor scrammed because of a grid disturbance, likely caused by a lighting pole knocked over by Sandy’s high winds.

An hour and forty-five minutes later, and 250 miles southeast, another of the nation’s ancient reactors also scrammed because of an interruption in offsite power. Indian Point, the very old and very contentious nuclear facility less than an hour’s drive north of New York City, shut down because of “external grid issues.” And Superstorm Sandy has given Metropolitan New York’s grid a lot of issues.

While neither of these shutdowns is considered catastrophic, they are not as trivial as the plant operators and federal regulators would have you believe. First, emergency shutdowns–scrams–are not stress-free events, even for the most robust of reactors. As discussed here before, it is akin to slamming the breaks on a speeding locomotive. These scrams cause wear and tear aging reactors can ill afford.

Second, scrams produce pressure that usually leads to the venting of some radioactive vapor. Operators and the NRC will tell you that these releases are well within “permissible” levels–what they can’t tell you is that “permissible” is the same as “safe.”

If these plants were offline, or running at reduced power, the scrams would not have been as hard on the reactors or the environment. Hitting the breaks at 25 mph is easier on a car than slamming them while going 65. But the NRC does not have a policy of ordering shutdowns or reductions in capacity in advance of a massive storm. In fact, the NRC has no blanket protocol for these situations, period. By Monday morning, regulators agreed to dispatch extra inspectors to nuclear plants in harm’s way (and they gave them sat phones, too!), but they left it to private nuclear utility operators to decide what would be done in advance to prepare for the predicted natural disaster.

Operators and the Nuclear Regulatory Commission spokes-folks like to remind all who will listen (or, at least, all who will transcribe) that nuclear reactors are the proverbial house of bricks–a hurricane might huff and puff, but the reinforced concrete that makes up a typical containment building will not blow in. But that’s not the issue, and the NRC, at least, should know it.

Loss of power (SBOs) and loss of coolant accidents (LOCAs) are what nuclear watchdogs were warning about in advance of Sandy, and they are exactly the problems that presented themselves in New York and New Jersey when the storm hit.

The engineers of the Titanic claimed that they had built the unsinkable ship, but human error, corners cut on construction, and a big chunk of ice cast such hubris asunder. Nuclear engineers, regulators and operators love to talk of four-inch thick walls and “defense-in-depth” backup systems, but the planet is literally littered with the fallout of their folly. Nuclear power systems are too complex and too dangerous for the best of times and the best laid plans. How are they supposed to survive the worst of times and no plans at all?

Alert Declared at Oyster Creek Nuclear Plant

Oyster Creek Nuclear Generating Station (photo courtesy of NRC)

The US Nuclear Regulatory Commission is reporting that an “alert” has been declared at the Oyster Creek Nuclear Generating Station in Ocean County, New Jersey. An alert is the second level on the four-point scale, a step above an “unusual event.”

The NRC declared the alert at 8:45 PM local time, as a combination of rising tides, wind and the storm surge from Hurricane Sandy caused water to rise above safe levels in the plant’s water intake structure. Sandy, which made landfall at around 8 PM in southern New Jersey with 90 mph winds, has caused power outages and widespread flooding along the Atlantic coast from Maryland to New York.

Oyster Creek is the oldest operating commercial reactor in the US. It is a GE boiling water reactor of similar design to the ones that failed in Fukushima, Japan during 2011’s Tohoku earthquake, though Oyster Creek is actually older. As Sandy moved up the coast, fears were raised about several nuclear facilities in the storm’s path. The NRC had issued no specific directives in advance of the hurricane, though extra inspectors were dispatched to threatened plants early on Monday.

Particular concerns were raised about Oyster Creek. The reactor is currently offline for maintenance, which means all the reactor fuel, along with generations of used fuel, is in the plant’s spent fuel pools. The plant itself is not generating any electricity, and so is dependent on external power. If the power were to fail, there would be no way to circulate cooling water through the pools.

Backup diesel generators typical to this design power the heat transfer from the reactor, but the so-called “defense in depth” backups for the spent fuel pools are the plant’s own electrical output and power from an external grid.

Flooding of the coolant intake structure further complicates matters. Oyster Creek does not have a cooling tower (like those seen in classic pictures of Three Mile Island). Safe temperatures are maintained by taking in massive amounts of water from a nearby source (in this case, Barnegat Bay). Water must continue to circulate in and out of the facility to keep temperatures at safe levels.

Another question would be whether floodwaters would carry additional radioactive contamination into Barnegat Bay as they recede.

In the NRC press release on Oyster Creek (PDF), the regulator also noted (with apparent pride) that no reactors had been shut down because of Hurricane Sandy. However, at least one reactor, Millstone 3 in Connecticut, had reduced output in anticipation of the storm. Several other reactors in the region are currently offline for refueling or maintenance.

Hurricane Sandy Brings Wind, Rain and Irony to US Nuclear Plants

Hurricane Sandy’s projected path as of 9 AM, Monday. (map courtesy of NOAA)

With Hurricane Sandy projected to make landfall hundreds of miles to the south and the predicted storm surge still over 24 hours away, New York City completely shuttered its mass transit system early Sunday evening. By 7 PM, all subway service was halted for only the second time in history. The fear, according to state authorities, is that heavy rainfall or the expected six-to-eleven-foot increase in tide levels would flood subway tunnels, stranding trains at various points across the 842 miles of track.

Fearing similar flooding, the Washington, DC, Metro is also expected to suspend service for all of Monday.

Twelve hours after NYC shut down its subways, at 7 AM Monday, with Hurricane Sandy lashing the Mid-Atlantic coast with heavy rain and 85 mph winds, at least a half-dozen commercial nuclear reactors lie in the storm’s projected path–and the US Nuclear Regulatory Commission has yet to issue any specific orders to the facilities it supposedly oversees. In fact, check out the NRC’s twitter feed or look at its website, and the only reference you will find to what has been dubbed “Frankenstorm” is the recently posted cancellation notice for a public hearing that was supposed to convene on Tuesday, October 30.

The subject of that meeting? The Fort Calhoun Nuclear Generating Station.

The Fort Calhoun plant sits on the Missouri River, on the eastern edge of Nebraska, near the town of Blair. Fort Calhoun’s single pressurized water reactor was shutdown for refueling in April of last year, but floods during the summer of 2011 encircled the facility and caused a series of dangerous incidents. A breach in water berms surrounded transformers and auxiliary containment buildings with two feet of water. Around that same time, a fire shut down power to Fort Calhoun’s spent fuel pools, stopping the circulation of cooling water for 90 minutes and triggering a “red event,” the second most severe classification. Outside of its reactor, the Nebraska facility is home to approximately 800,000 pounds of high-level radioactive waste. To this day, Fort Calhoun is offline and awaiting further evaluation by the NRC.

That a hearing on a flooded plant has been postponed because of the threat of flooding near NRC offices seems like the height of irony, but it pales next to the comparison of safety preparedness measures taken by New York’s Metropolitan Transit Authority for a subway and the federal government’s approach to a fleet of nuclear reactors.

That is not to say that the NRC is doing nothing. . . not exactly. Before the weekend, regulators let it be known that they were considering sending extra inspectors to some nuclear facilities in Sandy’s path. Additionally, regional officials stressed that plant operators were doing walk downs to secure any outside equipment that might become a sort of missile in the event of high winds. It is roughly the equivalent of telling homeowners to tie down their lawn furniture.

And it seems to be understood, at least at the nuclear plants in southern New Jersey, that reactors should be shutdown at least two hours before winds reach 74 mph.

To all that, the NRC made a point of assuring the public that reactor containment buildings could withstand hurricane-force winds, or any odd piece of “lawn furniture” that might be hurled at them.

That’s nice, but hardly the point.

Containment breech is always a concern, but it is not the main issue today. A bigger worry are SBOs–Station Black Outs–loss-of-power incidents that could impede a plant’s capacity to cool its reactors or spent fuel pools, or could interfere with operators’ ability to monitor everything that is going on inside those areas.

As reported last year, Hurricane Irene caused an emergency shutdown at Maryland’s Calvert Cliffs nuclear plant when aluminum siding torn off by high winds shorted out the main transformer and caused an explosion, damaging structures and equipment. Calvert Cliffs was one of the facilities that had chosen not to reduce output or shutdown in advance of Irene–especially alarming because just days before that storm, plant operators had reported trouble with its diesel backup generators.

Irene caused other problems, beyond loss of electricity to millions of consumers, public notification sirens in two emergency preparedness zones were disabled by the storm.

In sum, storm damage triggered a scram at a plant with faulty backup generators. If power had not been restored, backup would have failed, and the rising temperatures in the reactors and fuel pools would have necessitated an evacuation of the area–only evacuation would have been hampered because of widespread power outages and absent sirens.

The worst did not happen last year at Calvert Cliffs, but the damage sustained there was substantial, and the incident should serve as a cautionary tale. Shutting down a nuclear reactor doesn’t prevent every problem that could result from a severe storm, but it narrows the possibilities, reduces some dangers, and prevents the excessive wear and tear an emergency shutdown inflicts on an aging facility.

Calvert Cliffs is again in the line of fire–as are numerous other plants. Hurricane Sandy will likely bring high winds, heavy rain and the threat of flooding to nuclear facilities in Virginia, Maryland, New Jersey, New York and Connecticut. Given last year’s experiences–and given the high likelihood that climate change will bring more such events in years to come–it might have been expected that the NRC would have a more developed policy.

Instead, as with last year’s Atlantic hurricane, federal regulators have left the final decisions to private sector nuclear operators–operators that have a rather poor track record in evaluating threats to public safety when actions might affect their bottom line.

At the time of this writing, the rain in New York City is little more than a drizzle, winds are gusting far below hurricane strength, and high tide is still over ten hours away. Hurricane Sandy is over 300 miles to the south.

But Gotham is a relative ghost town. The subway turnstiles are locked; city busses are nowhere to be seen.

At the region’s nuclear facilities, however–at North Anna, Hope Creek, Salem and Oyster Creek, at Calvert Cliffs, Indian Point and Millstone–there is no such singular sense of better-safe-than-sorry mission.

In New York, it can be argued that the likes of Governor Andrew Cuomo and Mayor Michael Bloomberg have gone overboard, that they have made decisions based not just on safety, but on fears of political fallout and employee overtime. But in the Nuclear Regulatory Commission’s northeast region, there is no chance of that kind of criticism–one might even say there is no one to criticize, because it would appear that there is no one in charge.
