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.

TEPCO is the Japanese company that owns and operated the Fukushima nuclear power plant that suffered the devastating accident in March of 2011 following an earthquake and tsunami. As might be expected, this accident and the aftermath delivered a serious blow to the reputation of TEPCO. Reputation is important for any company anywhere in the world but especially so for a Japanese company. In order to help the company recover from the damage inflicted by the nuclear disaster at Fukushima, TEPCO enlisted a British-American lawyer named Barbara Judge who was once the chairperson of the United Kingdom Atomic Energy Authority. Beyond TEPCO, Abe, the new Japanese Prime Minister wants to export nuclear technology and it is hoped that Barbara Judge will be able to help restore confidence in the whole Japanese nuclear industry.
Mz. Judge is going to be the safety tsar for TEPCO. She is deputy chairperson of the company’s nuclear reform monitoring committee and head of several new safety commissions. She says that her mission is to make TEPCO a leader in nuclear safety. Her comments on the nuclear accident acknowledge that there were not clear lines of communication between the various players after the disaster and that this situation interfered with a proper response.
Fear of radiation is one of the big problems that Mz. Judge emphasizes. She says that there is more radiation exposure flying in an airplane that there would be walking through a nuclear plant. So her point seems to be that fear of radiation is overblown and that people need to be realistic. Then she turns to stoking fear of power black outs, dependence on outside sources of energy and sky high energy prices if Japan does not turn all its nuclear reactors back on and build new reactors. Apparently fear of not using nuclear power is just fine with Mz. Judge.
My problem with TEPCO’s plan for rebirth is that we have already seen this movie several times. TEPCO has been caught in the past seriously violating safety regulations. After criticism from the government, they have promised to clean up their act and be a model company with excellent safety culture and public transparency. Years go by and they are caught again. Once again they swear that this time they are really going to make positive changes. After going through this cycle several times, they knew of the danger of a tsumami and yet refused to move a critical backup generator above the level of a possible flood before the accident at Fukushima. Following the accident, there have been serious charges of unsafe practices and lack of transparency during the recovery from the disaster.
My great fear is that once again TEPCO will make promises it can’t or won’t keep despite the importation of Mz. Judge and that another accident will happen due to their negligence. This threatens not only Japan but also other countries who are buying Japanese nuclear technology from companies that cannot be trusted to fulfill their promises of safety and competence.

It has now been more than two years since the nuclear disaster at Fukushima, Japan triggered by a huge earthquake and tsunami. A great deal of time, money and energy has been expended by TEPCO which owns and operates the Fukushima nuclear power plant and agencies of the Japanese government such as the Nuclear Regulatory Agency in trying to understand exactly what caused the disaster and what has happened since the disaster. There are still unanswered questions about the situation such as what has happened to the cores of the reactors which melted down and how radioactivity is migrating underground with water being pumped into the damaged reactors.
The Nuclear Regulatory Agency of Japan is the agency directly responsible for regulating the nuclear industry in Japan. Although it has been accused of being too lenient and friendly with the Japanese nuclear industry, the NRA has repeatedly cited violation of regulations by TEPCO for decades at the nuclear plants they own and operate. Investigations have shown that the Fukushima disaster did not need to happen. TEPCO knew about problems at the power plant and ignored warnings and demands for changes. Following accidents there have been many criticisms of TEPCO for not taking proper action and for not honestly reporting on the situation at the plant.
One of the biggest concerns at Fukushima is that the cores of Unit One, Unit Two and Unit Three melted down and sank into the earth. It is unknown exactly where these hot melted cores are now. Water is being pumped into the ruins of the reactors to try to keep these cores as cool as possible where ever they are underground. The is a big problem with what is going to be done with all the water being pumped underground, partly because of how close the plant is to the ocean. There is already radioactive contamination of ocean water near Fukushima that is interfering with the fishing industry.
TEPCO has drafted a new report on the situation at the Fukushima plant and modified a plan for moving forward with decommissioning the damaged reactors. When TEPCO met with the NRA on June 28th, they proudly announced that they were actually ahead of the original schedule for dealing with the corium (melted core materials.) The NRA expressed extreme skepticism that the announcement of being ahead of schedule from TEPCO was meaningless because TEPCO didn’t even know where the corium was now and exactly what they would have to do to recover and/or neutralize it. Members of the NRA used a Japanese idiomatic expression that translates to “Drawing a picture of a sweet rice cake may look nice but you cannot eat it.”
I have returned to the Fukushima disaster and its aftermath again and again on this blog because I want the people in the United States to have some vague idea of just how damaging a nuclear accident can be in many ways to a nation. Two years after the Fukushima disaster, the situation continues to deteriorate and no one is sure exactly what to do.

A couple of days ago, I blogged about problems at Handford with the handling of two glove boxes by a Department of Energy contractor named Permafix. The boxes were moved from Hanford to Permafix through Richland with parade permits which were not appropriate for such a shipment. When the two glove boxes reached Permafix, there was radiation found on the outside of the plastic wrapped boxes and they were not handled properly when they were moved off the truck.
Coincidentally, the next day I heard a report on the radio that the Environmental Protection Agency was fining the DOE because the DOE and its contractors mishandled radioactive Hanford lab waste by transporting it without proper permits and dumping some of it into a landfill without proper processing. The EPA looked at records between the 1980s and 2011 and concluded that there was a consistent pattern of misbehavior. They levied a fine of $136,000 against the DOE. They admitted that the fine was small considering the severity of the problem but explained that if they raised the fine and/or the DOE contested the fine in court, it would take money away from the amount available to DOE to clean up the mess. I almost drove off the road! This would be like a prosecutor deciding not to fine a bank too much because the bank had to give money back to the people they had cheated and a big fine or expensive lawsuit would reduce the money available to pay back to the victims.
The idea of one department of the U.S. Executive Branch fining another department of the Executive Branch is a little odd. The issue of possible law suits between the EPA and the DOE was also raised. That also is a little odd. That would be like fines and lawsuits between departments of a corporation. It doesn’t really make sense to me. It would seem that if there were problems in the Executive Branch, there would be investigations and then some sort of action might be taken such as firing people and/or changing procedures. Any expenses that resulted from the problems should be taken care of in the budget for the department that is cleaning up the mess.
One of the reasons given for the small fine was that the DOE promised to deal with the problem and the EPA though that that was sufficient. Well, excuse me, but the incident that I blogged about two days ago where there were not proper permits and the contractor mishandled the glove boxes suggests to me that DOE and its contractors didn’t really take their promise to fix things very seriously. A slap on the wrist like the small fine is obviously not sufficient. People need to lose their jobs and the whole mess needs to be publicized. There are serious problems with the way that DOE and its contractors are handling the Hanford cleanup and something needs to be done to impress upon them the need for real change.
