The Senate Committee on the Environment and Public Works held a briefing on the “Nuclear Plant Crisis in Japan and Implications for the United States” on March 16th. Dr. Edwin Lyman, Senior Scientist of the Global Security Program at the Union of Concerned Scientists, was a witness. Here’s what he said (minus the introductory politeness:)
While the ongoing situation in Japan should be a main focus of U.S attention, we should not hesitate to ask ourselves whether we are doing all that we can do to prevent a Fukushima-like nuclear disaster from happening here.
Before proceeding, I would like to say that the Union of Concerned Scientists is neither pro nor anti-nuclear power, but has served as a nuclear power safety and security watchdog for over 40 years.
In the aftermath of the 1979 Three Mile Island accident, the NRC undertook a major overhaul of its rules to correct many of the regulatory weaknesses that the accident revealed. In contrast, seven years later, the Commission and the industry avoided learning any lessons from the far more severe Chernobyl accident because of the misleading claim that such an extreme release of radioactivity could never happen at a plant of Western design.
“It can’t happen here” is not a policy
However, the NRC and the industry cannot hide this time behind the “it can’t happen here” excuse. We have 23 plants of the same design. We have plants that are just as old. We have had station blackouts.
We have a regulatory system that is not clearly superior to that of the Japanese. We have had extreme weather events that exceeded our expectations and defeated our emergency planning measures (Katrina).
We have had close calls (e.g. Davis-Besse) that were only one additional failure away from becoming disasters. We have had full-blown disasters in other industries (e.g. BP). We have suffered a devastating terrorist air attack against our infrastructure for which we were completely unprepared.
What if Fukushima were happening here?
I would ask the Committee to imagine for a moment that the crisis unfolding at Fukushima is taking place in their home states, and to consider whether this is something that Americans should ever have to endure under any circumstances.
If the answer is no — the right answer, in our opinion — then it is incumbent on you to thoroughly investigate whether the risk of an American Fukushima is really as low as the NRC and the industry claim.
But even though it will be a long time before we learn all the lessons from the still-evolving disaster in Japan, it is not premature to immediately take steps to reduce vulnerabilities that have long been known by regulators but have not been addressed.
US has 31 plants similar to Fukushima
Safety margins eroded
There are many other areas where we believe the NRC has allowed safety margins to decrease too far. Now, not after an accident, is the time to reconsider whether the NRC’s position on “how safe is safe” is truly adequate to protect public health and safety.
Thank you for your attention, and I would be happy to answer any questions you may have.
