Quick Hits – The NRC, NYT and NRC Again

By

The Nuclear Regulatory Commission has posted an extremely useful FAQ about the Japan earthquake. The very first question answers a big one:

1) Can an earthquake and tsunami as large as happened in Japan also happen here?

This earthquake occurred on a “subduction zone”, which is the type of tectonic region that produces earthquakes of the largest magnitude. A subduction zone is a tectonic plate boundary where one tectonic plate is pushed under another plate. Subduction zone earthquakes are also required to produce the kind of massive tsunami seen in Japan. In the continental US, the only subduction zone is the Cascadia subduction zone which lies off the coast of northern California, Oregon and Washington. So, a continental earthquake and tsunami as large as in Japan could only happen there.

It goes on to note that only one nuclear power plant is in this area, the Columbia Generating Station in Washington, and it’s 255 miles from the coast (thus even further from the zone). That means the potent one-two punch suffered by Fukushima Daiichi cannot happen to a nuclear plant in the United States. That doesn’t absolve the industry from taking the lessons from this event, but it is mightily reassuring still.

And that’s just question 1. By all means, read the rest.

The New York Times has put up an interactive 3-D graphic showing how fuel is stored at boiling water reactors such as Fukushima Daiichi. Interesting presentation and a good explanation of why keeping the used fuel pools filled with water is so important.

The NRC is having a meeting. And you’re invited.

The U.S. Nuclear Regulatory Commission will be briefed by its staff on the NRC’s response to the ongoing nuclear event in Japan in a public meeting on March 21 at 9 a.m. at NRC Headquarters, 11555 Rockville Pike, Rockville, Md. The commission meeting will be open to public observation and will be webcast at: http://www.nrc.gov/public-involve/public-meetings/webcast-live.html.

This is what they’d call on Broadway a hard ticket, as you’d imagine, so the best bet, even if you live in the area, is to watch the hearing on the web or on C-Span, which will carry it.  It doesn’t look like there will be a q-and-a session, but it should be quite interesting.

Wednesday Update

By
From NEI’s Japan micro-site: NRC, Industry Concur on Many Post-Fukushima Actions Industry/Regulatory/Political Issues • There is a “great deal of alignment” between the U.S. Nuclear Regulatory Commission and the industry on initial steps to take at America’s nuclear energy facilities in response to the nuclear accident in Japan, Charles Pardee, the chief operating officer of Exelon Generation Co., said at an agency briefing today. The briefing gave stakeholders an opportunity to discuss staff recommendations for near-term actions the agency may take at U.S. facilities. PowerPoint slides from the meeting are on the NRC website. • The International Atomic Energy Agency board has approved a plan that calls for inspectors to evaluate reactor safety at nuclear energy facilities every three years. Governments may opt out of having their country’s facilities inspected. Also approved were plans to maintain a rapid response team of experts ready to assist facility operators recoverin...

Fluor Invests in NuScale

By
You know, it’s kind of sad that no one is willing to invest in nuclear energy anymore. Wait, what? NuScale Power celebrated the news of its company-saving $30 million investment from Fluor Corp. Thursday morning with a press conference in Washington, D.C. Fluor is a design, engineering and construction company involved with some 20 plants in the 70s and 80s, but it has not held interest in a nuclear energy company until now. Fluor, which has deep roots in the nuclear industry, is betting big on small-scale nuclear energy with its NuScale investment. "It's become a serious contender in the last decade or so," John Hopkins, [Fluor’s group president in charge of new ventures], said. And that brings us to NuScale, which had run into some dark days – maybe not as dark as, say, Solyndra, but dire enough : Earlier this year, the Securities Exchange Commission filed an action against NuScale's lead investor, The Michael Kenwood Group. The firm "misap...

Activists' Claims Distort Facts about Advanced Reactor Design

By
Below is from our rapid response team . Yesterday, regional anti-nuclear organizations asked federal nuclear energy regulators to launch an investigation into what it claims are “newly identified flaws” in Westinghouse’s advanced reactor design, the AP1000. During a teleconference releasing a report on the subject, participants urged the Nuclear Regulatory Commission to suspend license reviews of proposed AP1000 reactors. In its news release, even the groups making these allegations provide conflicting information on its findings. In one instance, the groups cite “dozens of corrosion holes” at reactor vessels and in another says that eight holes have been documented. In all cases, there is another containment mechanism that would provide a barrier to radiation release. Below, we examine why these claims are unwarranted and why the AP1000 design certification process should continue as designated by the NRC. Myth: In the AP1000 reactor design, the gap between the shield bu...
