Yule Fuel

8:30 am in Uncategorized by Gregg Levine

Yes, it’s time for that metaphor again. If you grew up near a TV during the 1960s or ’70s, you probably remember the ever-burning Yule Log that took the place of programming for a large portion of Christmas Day. The fire burned, it seemed, perpetually, never appearing to consume the log, never dimming, and never, as best the kid who stared at the television could tell, ever repeating.

Now, if you have been watching this space about as intently as I once stared at that video hearth, perhaps you are thinking that this eternal flame is about to reveal itself as a stand-in for nuclear power. You know, the theoretically bottomless, seemingly self-sustaining, present yet distant, ethereal energy source that’s clean, safe and too cheap to meter. Behold: a source of warmth and light that lasts forever!

Yeah. . . you wish! Or, at least you’d wish if you were a part of the nuclear industry or one of its purchased proxies.

But wishing does not make it so. A quick look at the US commercial reactor fleet proves there is nothing perpetual or predictable about this supposedly dependable power source.

Both reactors at San Onofre have been offline for almost a year, after a radioactive leak revealed dangerously worn heat transfer tubes. Nebraska’s Fort Calhoun plant has been shutdown since April of 2011, initially because of flooding from the Missouri River, but now because of a long list of safety issues. And it has been 39 months since Florida’s Crystal River reactor has generated even a single kilowatt, thanks to a disastrously botched repair to its containment that has still not been put right.

October’s Hurricane Sandy triggered scrams at two eastern nuclear plants, and induced an alert at New Jersey’s Oyster Creek reactor because flooding threatened spent fuel storage. Other damage discovered at Oyster Creek after the storm, kept the facility offline for five weeks more.

Another plant that scrammed during Sandy, New York’s Nine Mile Point, is offline again (for the third, or is it the fourth time since the superstorm?), this time because of a containment leak. (Yes, a containment leak!)

Other plants that have seen substantial, unplanned interruptions in power generation this year include Indian Point, Davis-Besse, Diablo Canyon, Hope Creek, Calvert Cliffs, Byron, St. Lucie, Pilgrim, Millstone, Susquehanna, Prairie Island, Palisades. . . honestly, the list can–and does–go on and on. . . and on. Atom-heads love to excuse the mammoth capital investments and decades-long lead times needed to get nuclear power plants online by saying, “yeah, but once up, they are like, 24/7/365. . . dude!”

Except, of course, as 2012–or any other year–proves, they are very, very far from anything like that. . . dude.

So, no, that forever-flame on the YuleTube is not a good metaphor for nuclear power. It is, however, a pretty good reminder of the still going, still growing problem of nuclear waste.

December saw the 70th anniversary of the first self-sustaining nuclear chain reaction, and the 30th anniversary of the first Nuclear Waste Policy Act. If the 40-year difference in those anniversaries strikes you as a bit long, well, you don’t know the half of it. (In the coming weeks, I hope to say more about this.) At present, the United States nuclear power establishment is straining to cope with a mountain of high-level radioactive waste now exceeding 70,000 tons. And with each year, the country will add approximately 2,000 more tons to the pile.

And all of this waste, sitting in spent fuel pools and above-ground dry casks– supposedly temporary storage–at nuclear facilities across the US, will remain extremely toxic for generations. . . for thousands and thousands of generations.

There is still no viable plan to dispose of any of this waste, but the nation’s creaky reactor fleet continues to make it. And with each refueling, another load is shoehorned into overcrowded onsite storage, increasing the problem, and increasing the danger of spent fuel accidents, including, believe it or not, a type of fire that cannot be extinguished with water.

So, if you want to stare at a burning log and think about something, think about how that log is not so unlike a nuclear fuel assembly exposed to air for a day or two. . . or think of how, even if it is not actually burning, the high levels of radiation tossed out from those uranium “logs” will create heat and headaches for hundreds of thousands of yuletides to come.

Oh, and, if you are still staring at the Yule log on a cathode ray tube television, don’t sit too close. . . because, you know, radiation.

Merry Christmas.

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

7:10 am in Uncategorized by Gregg Levine

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.

End-of-Summer News Puts Nuclear Renaissance on Permanent Vacation

The Nuclear Regulatory Commission cannot issue a license for the construction and operation of a new nuclear reactor in Maryland–that is the ruling of the NRC’s Atomic Safety and Licensing Board (ASLB) handed down Thursday.

In their decision, the ASLB agreed with intervenors that the Calvert Cliffs 3 reactor project planned for the shores of Chesapeake Bay violated the Atomic Energy Act’s prohibition against “foreign ownership, control, or domination.” UniStar, the parent company for the proposal, is wholly owned by French energy giant Électricité de France (EDF).

EDF had originally partnered with Constellation Energy, the operator of two existing Calvert Cliffs reactors, but Constellation pulled out of the project in 2010. At the time, Constellation balked at government requirements that Constellation put $880 million down on a federal loan guarantee of $7.6 billion (about 12 percent). Constellation wanted to risk no more than one or two percent of their own capital, terms the feds were then willing to meet if Constellation and EDF could guarantee the plant’s completion. Constellation also found that requirement too onerous.

Constellation has since been purchased by Exelon.

The ASLB decision technically gives EDF 60 days to find a new American partner, but given the history and the current state of the energy market, new suitors seem highly unlikely. It marks only the second time a license has been denied by the ASLB. (The first, for the Byron, Illinois plant in 1984 was overturned on appeal. Byron opened the next year, and Illinois’s groundwater has never been the same.) The NRC also declined to grant a license to the South Texas Project late last year when US-based NRG Energy (corporate ID courtesy of the Department of Redundancy Department) pulled out of the project, leaving Japanese-owned Toshiba as the only stakeholder.

The Calvert Cliffs intervenors were led by the Nuclear Information and Resource Service (NIRS), which has been fighting Calvert Cliffs 3 almost since its inception. NIRS was joined by Beyond Nuclear, Public Citizen and Southern Maryland CARES.

Michael Mariotte, Executive director of NIRS, called Thursday’s decision “a blow to the so-called ‘nuclear renaissance,’” noting that back in 2007, when permit requests were submitted for Calvert Cliffs 3, the project was considered the “flagship” of a coming fleet of new reactors. “Now,” said Mariotte, “it is a symbol for the deservedly failed revival of nuclear power in the US.”

A symbol, yes, but far from the only symbol. Read the rest of this entry →

San Onofre: One Leaks, the Other Doesn’t… Yet

11:30 am in Uncategorized by Gregg Levine

For those who thought that, with the new year, nuclear power had turned a page and put its “annus horribilis” behind it–as if the calendar were somehow the friend America’s aging reactors–let’s take a quick look at January 2012.

First, a glance across the Pacific, where the month began with the revelation that the Japanese government purposely downplayed their assessments of the Fukushima disaster–hiding the worst projected scenarios from the public from soon after the March earthquake by classifying the documents as personal correspondence–and ended with discovery of yet another large leak of radioactive water from one of the crippled reactors.

Closer to home, the lone reactor at Wolf Creek, Kansas, was shutdown on January 13 after the failure of a main generator breaker was followed by a still-unexplained loss of power to an electrical transformer. Diesel generators kicked in to run the safety systems until external power was restored, but the plant remains offline while a Nuclear Regulatory Commission inspection team tries to figure out what went wrong.

On the morning of January 30, a power failure caused a reactor at Exelon’s Byron Generating Station to scram, which in turn required a wee bit of venting: Read the rest of this entry →

Gregory Jaczko Has a Cold

8:30 am in Uncategorized by Gregg Levine

In April 1966, Esquire Magazine published a story by Gay Talese that is still considered one of the greatest magazine articles of all time; the article, the cover story, was titled “Frank Sinatra Has a Cold.”

The piece, still very much worth the read, says much about celebrity, journalism, and, of course, celebrity journalism, but germane here is a point Talese makes early on: for most people, having a cold is a trivial matter–after all, it’s called the “common” cold–but when a man, a cultural icon, a giant of stage and screen like Sinatra (remember, this is 1966) has a cold, well. . . .

Frank Sinatra with a cold is a big deal. It affects him, his mood, his ability to perform, and so it affects his friends, his entourage, his personal staff of 75, his audience, and perhaps a part of the greater popular culture. In other words, as Talese wants you to understand, in this case, a cold is anything but trivial.

Gregory Jaczko, the chairman of the United States Nuclear Regulatory Commission, made some comments to the press earlier this week. Jaczko, it seems, is worried. He believes, as noted in an Associated Press story, that “U.S. nuclear plant operators have become complacent, just nine months after the nuclear disaster in Japan.” The NRC head thinks that a slew of events at over a dozen domestic nuclear facilities reveal the safety of America’s reactors to be something less than optimal.

To be clear, safety concerns at any kind of plant, be it a soda bottler or a microchip manufacturer, are probably not trivial, but when the safe and secure operation of a nuclear facility comes into question–as the aftermath of Chernobyl or the ongoing crisis in Japan will tell you–it ratchets up concern to a whole different level. So, when the man who more or less serves as the chief safety officer for the entirety of the nation’s nuclear infrastructure says he’s worried, many, many other people should be worried, too.

To put it another way, Greg Jaczko has a cold.

But that’s not the scariest part. Read the rest of this entry →

NRC Chair Jaczko: Events Like Fukushima Too Rare to Require Immediate Changes

For those that think nothing has changed in United States regulation since the Japanese earthquake and tsunami started the ongoing crisis at the Fukushima Daiichi nuclear facility, think again. The pre-disaster mentality of “What could possibly go wrong?” has been replaced with reassurances that “Stuff like that hardly ever happens!”

At least that is the impression conveyed by the current chairman of the US Nuclear Regulatory Commission, Gregory Jaczko, in a pair of early October interviews. During two NRC-sponsored events, Jaczko fielded questions first from nuclear industry professionals and those considered friendly to the expansion of nuclear power, and then, in a separate session two days later, responded to representatives from public interest groups and other individuals generally seen as opposed to nuclear energy.

While the tone of the questions differed somewhat predictably in the two sessions, Chairman Jaczko’s attitude did not. Jaczko took several opportunities to praise the NRC staff and the processes and protocols used by the commission, repeating in both panels that the primary duty of his agency is ensuring the safety of nuclear facilities in the United States.

Beyond his broad assurances and patient, capable demeanor, however, many of the chairman’s assertions about both the NRC process and the progress being made toward his stated safety goals highlighted notable contradictions and troubling biases inherent in America’s nuclear regulatory regime.

To be fair, the pre-Fukushima outlook was not exactly “What could possibly go wrong?” In terms of the types of accidents and the repercussions of contamination, containment breaches, radioactive releases, meltdowns, melt-throughs, and a host of other undesirable situations, regulators and industry insiders alike were probably quite aware of what could go wrong. But as US nuclear proponents and profiteers strove to convey the impression of an informed industry, they also moved to downplay the threats to public safety and made sure to stress that, when it came to disaster scenarios, they had it covered.

The Party Line – September 23, 2011: In Post-Fukushima Reality, What is the Future, and Who is Winning It?

8:25 pm in Uncategorized by Gregg Levine

Beginning a story with a correction for what might seem a technical detail might not provide the most attention-grabbing lede, but it opens the door to a broader, and important, observation.

Last week’s column contained reference to “large nuclear power-generating nations,” and then listed Australia as part of that group. That, as pointed out by reader Dgdonovan, was incorrect:

Australia is not a large nuclear power producing nation, in fact none of Australia’s electricity is produced by nuclear power. Australia is a large uranium producing nation, however.

Indeed, while Australia may posses nearly a quarter of the world’s remaining uranium deposits, it has not commissioned a single industrial-scale nuclear reactor for electrical power generation. Read the rest of this entry →

The Party Line – September 2, 2011: Earthquakes, Hurricane Highlight Serious Flaws with Nuclear Power and Its Regulation

12:39 pm in Uncategorized by Gregg Levine

On Friday, August 26, as Hurricane Irene began its slow journey up the US central Atlantic coast, power companies operating 20 nuclear rectors in nine states made plans to deal with the storm and its potential aftermath.

North Carolina’s Brunswick reactors, operated by Progress Energy, were powered down to 70 percent of peak capacity. At New Jersey’s Oyster Creek, near Barnegat Bay, plant operator Exelon chose to shutdown its reactor completely. Dominion Resources, owner of New London, Connecticut’s Millstone plant took one reactor down to 70 percent, the other to 50 percent.

Dominion’s Surry plant in Virginia stayed at full power, as did Entergy’s Indian Point, 35 miles north of New York City, and the Pilgrim plant in Massachusetts.

The reason some plants chose to reduce output or go offline was because, if an accident caused or required the plant to scram–that is, quickly and completely shut down–the stress on the reactor increases the chance of a future safety breach. As Bob Alvarez, of the Institute for Policy Studies, explains: Read the rest of this entry →
