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.

  • Radioactive Waste 51 – August Update on the Magnuson Park Cleanup

               Following the last meeting in July on the radium contamination at Magnuson Park, I was given to understand by the Washington State Department of Ecology (WSDOE) that the period for public comments was being extended to August 31st. However, I found out last Saturday that the Navy’s period for public comments had quietly ended the day before on July 26th. The WSDOE has shown reluctance to challenge the Navy and it looks like the Navy may just proceed with its original plan.

               There has been a lot of confusion over the past few months about who has the ultimate authority at Magnuson Park. It appears from Federal and State laws that WSDOE has to sign off on the cleanup. From what I have been told at the meetings I attended, WSDOE does not have the ability or maybe just the will to prevent the Navy from proceeding with their original plan absent environmental impact statements and other documents required by law or regulation. After the current cleanup is executed, WSDOE can go to the Navy and say that they have not done enough. Whether or not the Navy would respond with further work, only the future knows.

                The Navy has not investigated the gravel and soil around the drain pipe from the radium room. They have checked the pipe to the point where it enters other pipes that are in use and they claim to have found no radioactive contamination. However, it turns out that there are Navy records of tests on the drain pipe that do show radioactive contamination. They say that they couldn’t investigate the rest of the pipe out to Lake Washington because it was still in use and full of water. The drain pipes are surrounded by gravel to allow drainage at flanges between the sections of pipes. Water flowing through the pipes would carry most contamination away but contaminated water that leaked into the gravel would not move quickly through the soil so it should concentrate any contaminants near the pipe.  There has also been no testing of the soil at the bottom of Lake Washington where the pipe system drains into the lake at the boat dock and swimming area. The excuse given was that rocks had been dumped on the bottom and that made it very difficult to suck up silt for testing. There is also the problem of hot spots of strontium and cesium at the park. The Navy has no idea of where they came from and I have not heard of a plan to clean them up.

               The Navy has made reference to the US Department of Energy (USDOE) and the Environmental Protection Agency (EPA) cleaning up of part of the Hanford Nuclear Reservation to a level of fifteen milliRems in justifying its plan to clean up Magnuson Park to 15 milliRems. That could result in almost one extra cancer per one thousand park users from long term exposure. Apparently the Navy is not aware that the public was told in the recent Hanford 300 Area briefing in Seattle that the USDOE and EPA no longer considered the fifteen milliRems level to be safe for public use areas. The Federal standard is one cancer per ten thousand people and the WSDOE standard is one cancer per one hundred thousand people.

               The Navy has been displaying arrogance, a reluctance to share important information and a distinct lack of concern for Federal and State laws and regulations concerning such cleanups. Let us hope that the WSDOE holds the Navy to a higher standard in the cleanup of Magnuson Park than the Navy hold itself.

  • Radioactive Waste 50 – USDOE Hanford 300 Area – Part 4 of 4

    Notes on public meeting held at the Seattle University Heights Center on July 31, 2013 by the United States Department of Energy (USDOE) at Hanford to explain planned cleanup of Hanford 300 Area and solicit public comment.

    Part 4 of 4

              I mentioned that I had worked with the Yakima Indian Nation around 1980 on finding a nuclear contractor to help them monitor the Hanford cleanup and that USDOE were still fumbling around trying to clean up the mess thirty years later. I said that the USDOE at Hanford had been dishonest, incompetent and had repeatedly broken the law. I mentioned the mess with the leaking tanks of waste and the vitrification plant project that had to be halted because of poor design. I pointed out that after all these years they are still not sure of exactly what is buried under Hanford and what other surprises like the rising uranium levels might be waiting for us down the road. I insisted that five years was too long to wait to see if their wonderful solution worked and that the situation needed to be monitored constantly. There were echoes of the Magnuson Park arguments with respect to the safe levels to leave in the soil. I suggested that the USDOE and the EPA should have a chat with the Navy and point out that they didn’t believe that the level the Navy wants to leave at Magnuson Park was safe for human beings. I finally said that I had no confidence in their planning, their execution and their honesty with respect to this cleanup plan.

              Representative Gerry Pollet was the last person who had signed up to comment. He went over some of the important issues such as the safe level of radiation after a cleanup. While the Hanford rep insisted that they were working at the one cancer in ten thousand level, Gerry pointed out that their published documents still had the eight cancers in ten thousand level. He said that the state planned to permanently raise the level of Columbia and that there was no mention of the problem of more uranium being released by the higher level. There are rules about having industrial levels closer than two hundred feet from a recreation use riverbank and yet the designated industrial area in the 300 Area was much closer than that. He also took issue with the idea that the only way to control the dust and insure the safety of the workers would be to spay large amounts of water on the ground. He said that there were other ways of controlling dust that would not result in washing more uranium into the soil and he asked why none of them had been mentioned or explored. He also complained that the definition of the industrial area was much too broad and covered parts of the 300 Area that were not eligible.  He asked about a consultation with state officials that the Hanford people were not able to provide. He remarked that the EPA had made earlier statements with respect their authority to override USDOE plans at Hanford and that he was disappointed that the EPA had apparently abandoned their position and accepted the USDOE plans.  In closing, he insisted that this plan was not well-thought out and that it should be seriously reconsidered and revised before implementation. He lamented the fact that the Washington State Department of Ecology was not participating in the meeting other than as moderator and expressed the hope that the WSDOE would step in and exert their legal authority with respect to the clean up. He also said that the Hanford USDOE plan failed to meet state legal standards as required by Federal law.

            I got a real sense of déjà vu all over again as I watched the meeting proceed. Just as at the Magnuson Park meeting, a department of the Federal Government failed to publicize a meeting well, failed to allow adequate time for their presentation and public questions and comments, failed to answer pointed and relevant questions adequately, left important information out of their presentation, failed to explain why they were not following the state and Federal laws with respect to such cleanups and really seemed to be conducting the meeting more to reassure the public that all was well as opposed to sincerely wanting public input to their process.

  • Radioactive Waste 49 – USDOE Hanford 300 Area – Part 3 of 4

    Notes on public meeting held at the Seattle University Heights Center on July 31, 2013 by the United States Department of Energy (USDOE) at Hanford to explain planned cleanup of Hanford 300 Area and solicit public comment.

     Part 3 of 4

            The question and answer period came next. A rep from Hanford Challenge, a non-profit group, brought up the question of thorium. He said that he had found high levels of thorium while exploring the 300 Area and that there was a legend on the map that said thoria trench. The geologist said that they found no significant levels of thorium on the site but did not explain about the trench.

            Someone questioned the ability of the DOE to maintain fences and guards over a period of decades and asked about the possibility of changes to the industrial zoning. They were assured that DOE would be able to do it safely.

            Washington State Representative Gerry Pollet who is also with Heart of America Northwest raised the issue of the acceptable contamination level. He had an argument with one of the Hanford reps who insisted that they were going for the one in ten thousand cancers and not the eight in ten thousand cancers that had been in one of the Hanford documents about the project.

             Following the Q & A, came the time for formal comments. I always find it strange at this type of meeting that the formal comments are on the record but the Q and A section is not on the formal record. If I were cynical, I would think that the people answering the questions were reluctant to have their answers on the record.

             A man with the Washington Physicians for Social Responsibility brought up the fact that there was no mention of the possibility of biological reconcentration of the uranium by plants and animals downriver from Hanford.

             The man from Hanford Challenge brought up the thorium again and pointed out that there was definitely high levels of thorium in the 300 Area that needed attention.

             The Native Americans in the area were brought up. Commenters complained that the Indians had treaty rights to use that land and fish the river and they were engaged in those activities right now while the uranium level was unsafe.

              Current recreational use of the riverbank by boaters, fishermen, families with children, windsurfers, kayakers and hikers was mentioned. The Columbia River periodically rises and resoaks the soil with containing the uranium. The river then drops back to a low level and the groundwater flows out of springs on the riverbank. This groundwater would carry unsafe levels of uranium, exposing the recreational users.

               Another man with the Washington Physicians for Social Responsibility brought up the fact that over eight trillion dollars had been spent creating nuclear weapons at Hanford. The billion dollars that was tossed around as a figure for the cleanup was far too little to do the job quickly and properly but was a tiny fraction of the money spent by the DoD on weapons. A woman said that would seem that the Defense Department could spare a few billion out of the five hundred billion defense budget to clean up their mess at Hanford.

               There were several comments from Heart of America members questioning the ability of DOE to maintain control of the fenced of industrial areas in the 300 Area for decades. One member insisted that the cleanup should be done thoroughly and quickly. Another complained about the publicity and low attendance.

  • Radioactive Waste 48 – USDOE Hanford 300 Area – Part 2 of 4

    Notes on public meeting held at the Seattle University Heights Center on July 31, 2013 by the United States Department of Energy (USDOE) at Hanford to explain planned cleanup of Hanford 300 Area and solicit public comment.

    Part 2 of 4

    A Hanford rep started off the official presentation with a few slides of the site and a very general overview. Apparently six alternatives were being considered. They were

    1. Do nothing
    2. Watch closely
    3. Dig up and dispose of some dirt and phase in use phosphates to bind the uranium in the soil in above the groundwater, watch closely

    3a. Dig up dirt and use phosphates to bind the uranium in the soil over entire area of concern, watch closely

    1. Dig down to level of the top of groundwater when the river is lowest in some areas and dispose of dirt in, watch closely
    2.  Dig down to level of the top of groundwater when the river is lowest in broad areas and dispose of dirt in watch closely

            Following that intro, a Hanford geologist came on and gave a very detailed technical presentation with lots of dense slides and technical jargon. He went over details of different problems on the site, the way that uranium moves underground, groundwater levels and flows, remediation methods, problems with dust in digging up and carting off the dirt, details of the phosphate soil binding and so on. On the question of why they didn’t just dig up the contaminated soil down to thirty feet, he said that the amount of water that they would have to spray on the site to keep the dust down would wind up causing even more uranium to leach into the ground water than if they left it alone.

             According to the geologist’s explanation, there was no danger to the people using the area and Hanford authorities had a good plan that should work. There seemed to be some confusion about the timeline. The plan said that the uranium levels should be safe for drinking water in about thirty years. However, the geologist said that he felt more confident with a number like fifty years. That is quite a difference! They were going to do a review in five years and see if it was working. Unfortunately, if it was not working in five years, they had no alternative plan.

            There were a number of other pollutants that had been identified in the 300 Area soil such as tritium, radioisotopes of cesium, strontium, and cobalt as well as chemicals such as polychlorinated biphenyls and trichloroethylene which are very dangerous. While these are going to being monitored, there were no plans for cleaning them up. The presentation and cleanup plan were strictly for uranium.

            There was too much technical detail and jargon in the geologist’s presentation for anyone who was not a nuclear engineer. He was supposed to present his part in about twenty five minutes but it took more like fifty minutes putting the meeting way beyond schedule. When it was time for Q & A, there as discussion of going on to the formal comment section first but it was decided to have a short Q & A. The management of this meeting reminded me of the recent Magnuson Park meetings on radioactive contamination there.
