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.
