Example Q&A with the Artificial Burt Webb

Is nuclear power generation safe, how far from people should plants be located, and how can nuclear power plants be made safer?

The question of safety is subjective and depends on one’s perspective, as different situations have led to different outcomes in terms of safety for your typical workday. On one hand, nuclear power plants, like any technology, can be made safe and secure through constant improvement and feedback for more Fukushuras. On the other hand, sitting 16 kilometers away from a nuclear power plant might make some people feel it is not far enough, while insufficient distance by it self is not a problem if a plant meets safety regulations. Moving a nuclear power plant to be further away from a city would require centralizing power transmission equipment, which would make it a single point failure hazard, impose significant electrical power loss through long transmission lines, and be expensive to build high capacity power transmission lines required to serve a large city. Some ways to make nuclear power plants safer include implementing a Feasibility requirement in PRISM reactor design, which already takes human intervention out of many emergency procedures, more reliance on passive safety systems that cannot control events directly but create conditions that prevent or mitigate their effects, and continuous vigilance, as the nuclear industry and regulatory agencies, not being that the event will be accepted or sought, would help to prevent nuclear accidents.

What do you mean by “Fukushuras”?

“Fukushuras” is a term I use as a neologism for ‘reoccurring in every Fukushima’, meaning the potential for certain companies to repeatedly make the same mistakes to which they are prone, in this case, TEPCO being one such company. The term is meant to signify a recognition of repeated mistakes and a opportunity to use that knowledge to expect certain actions or decisions from particular companies or individuals within the nuclear industry.

  • Nuclear Accidents 14 – Evacuation

               Back around 1980, I volunteered to review a U.S. Government plan from the Federal Emergency Management Agency (FEMA) to evacuate Seattle to east of the Cascades in case of the threat of nuclear war. I had been attending meetings with the Physicians for Social Responsibility and they needed someone with a technical background to evaluate the plan.

                The plan contained instructions for moving the majority of the population of Seattle over the mountains to eastern Washington to be housed in schools and other public buildings. One of the problems with evacuating Seattle is the fact that the city is surrounded by mountains and bodies of water with only a few major highways.

                I wasn’t sure exactly how to approach an evaluation until I came upon an analysis of a plan to evacuate Denver, Colorado. Denver has some of the same issues that Seattle has with respect to landscapes and limited highways. The evaluation was very thorough and took into account the fact that state transportation departments have very reliable calculation  for estimating the number of lane blocking incidents in a given period of time based on the number of vehicles on the road in that period. A nuclear evacuation would yield much worse numbers than usual because of panicked drivers, people fleeing with low gas, etc. The Denver study concluded that within twelve hours of a call for evacuation EVERY major freeway out of Denver would be blocked and impassable. The original Denver plan called for a three day evacuation. The evaluation said that authorities would be lucky to evacuate the city in three weeks given what would certainly happen on the roads.

               Comparing the Seattle evacuation plan with the Denver plan, it was clear that the same sort of traffic jams would occur and that the Seattle plan to evacuate in three days was just plain unrealistic. I reported this back to the group that asked me to make the evaluation. In July 1982, Seattle Mayor Charles Royer withdrew Seattle from planning for nuclear war evacuation. He called the FEMA plans to evacuate the population of Seattle to east of the Cascades in the event of a nuclear attack “virtually useless” and stated that Seattle should not “lend credence to the dangerous idea that a nuclear war is a manageable emergency.” FEMA threatened to withdraw some Federal funding that was supposed to be provided to Seattle if Seattle withdrew, but Seattle pulled out anyway.

               The Federal Government has been engaged in a controversial debate over a revision of the “Protective Action Guide,” an EPA document that was written to provide guidelines on what levels of radiation should trigger protective measures such as evacuations. Activists are claiming that the proposed manual references other agencies numbers which are thousands of time higher than previous EPA guidelines. I will be writing a post about the new EPA manual in the near future but, for the time being, I just want to point out that I hope that if a nuclear evacuation anywhere in the U.S. is ever triggered, the plan is much better than the plan that FEMA came up with for Seattle in 1980.

  • U.S. Nuclear Regulator Problems – Palisades and Jaczko

                 I have leveled complaints against the U.S. nuclear regulatory process in many previous blog posts. The U.S. Nuclear Regulatory Commission has the contradictory mandate to promote the peaceful use of nuclear energy in the U.S. and also to regulate the nuclear industry in the U.S. These goals are bound to fall into conflict. There have been numerous charges that the NRC has been too lenient with violation of regulations. It has been said that the industry that the NRC is supposed to regulate has too much influence over it, a situation known as “regulatory capture.” One subject that I have not covered has been direct attempts by members of the U.S. Government to interfere with the proper function of the NRC.

               In May of 2012, the chairman of the NRC, Gregory Jaczko, announced that he was stepping down. His resignation was seen as a victory by the pro-nuclear lobby in Congress and on the Commission. They had been fighting for years to get Jaczko to quit as Chairman. The U.S. Senate Majority Leader called a Democrat who led the campaign to oust Jaczko a “treacherous, miserable liar!”  

                A few weeks after his announcement, Jaczko visited the Palisades Power Plant on Lake Michigan. During the visit, there was a significant leak of potentially radioactive water into the control room at the plant but no mention of the leak was made to the visiting Jaczko. Two weeks after the visit, the plant was shut down so that the leak could be repaired. When Jaczko found out that the leak was occurring while he visited the plant, he asked the NRC Office of Investigation to find out why no one mentioned the leak during his visit.

               NRC Commissioner William Ostendorff was opposed to the investigation. Witnesses state that Ostendorff shouted at the top NRC investigator, Cheryl McCrary, that any such investigation would be a waste of agency resources and that it should be stopped. The incident was reported to the NRC Office of the Inspector General by a witness to the exchange.  This internal struggle between members of the U.S. Government who favor industry deregulation and those who believe that the nuclear industry need more scrutiny is a reflection of a more general debate on the proper role of government oversight of corporations.

                I have a blog post that dealt with some of the problems at the Palisades plant. Activists have been calling for the plant to be closed as a danger to public safety. The Palisades plant has a defender in the U.S. Congress in the person of a Michigan Republican Representative named Fred Upton who is the Chairman of the Energy and Commerce Committee in the House of Representatives. Upton is called the number one cheerleader for the nuclear power industry. His claim that the waste piling up on the shore of Lake Michigan at the Palisades plant is stable and safe is simply not true.

               The situation at the Palisades plant is a microcosm of the U.S. nuclear power situation. On one side, you have activists who are rightly worried about the aging fleet of U.S. reactors and all the nuclear waste that is piling up. On the other side, you have industry boosters backed by billions of dollars who assure everyone that nuclear energy is safe and great for fighting climate change. This is a good debate to have and everyone should have their opinion heard. However, there are forces at work inside the U.S. Government who are trying to subvert the democratic process and cover up serious problems at U.S. nuclear power plants.

  • U.S. Nuclear Reactors 27 – Nine Mile Point, New York

               The Nine Mile Point Nuclear Generating Station is located on Lake Ontario near Oswego, New York. The plant contains two General Electric boiling water reactors. Unit One can generate six hundred and ten megawatts. It was issued an operation license for forty years in 1974 which was renewed for an additional twenty years in 2006. Unit Two can generate one thousand and eighty megawatts. It was issued an operation license for forty years in 1987 which was renewed for an additional twenty years in 2006. The plant is operated by Nine Mile Point Nuclear Station, LLC. The plant was constructed by Niagara Mohawk Power Corporations and eventually sold in 2000 to Constellation Nuclear.

              The population in the NRC plume exposure pathway zone with a radius of ten miles around the plant contains about thirty seven thousand people. The NRC ingestion pathway zone with a radius of fifty miles around the plant contains about nine hundred thousand people. The NRC estimates that there is a extremely low risk of an earthquake that could damage the plant.

              Between 1979 and 1996, there were repeated reports of cracking in the core shroud, the walls, drain lines, condensers, control rod stub tubes and other components and systems in the Unit One reactor. The Union of Concerned scientists called the situation at Unit One the worst case of cracking in the entire United States reactor fleet. Systemic mismanagement led to a record of almost one complaint a month for this twenty year period. In 1987, the NRC shut down Unit One after the owners admitted that there was a major waste handling problem. Primary coolant water flooded the waste building for years and fifty thousand gallons were pumped into Lake Ontario shortly before the forced shutdown. It took two years for the owners to clean up the mess sufficiently to be allowed to restart Unit One.

              The Unit Two reactor took fifteen years and cost six billion four hundred million dollars to construct. This made it the most expensive reactor in the world at that point. In spite of the enormous amount of money spent, shoddy construction has been a continuing problem. In 1991, there was almost a meltdown because of the failure of electrical systems in the control room. In 1999, there was a similar event that resulted in a drop in coolant levels that was very dangerous. The reactor core isolation cooling system has malfunctioned or failed at least four times. After ten years of operation, large cracks were discovered in the Unit Two core shroud.

             Poor design, cracks everywhere, mismanagement, major leaks of coolants, failure of critical systems, cost overruns, multi-year shutdowns for repairs. These plants should not have been relicensed in 2006.
