NRC Petition on Spent Fuel Pools

Eric:
 
My group, the Foundation for Resilient Societies, has a proposal for safety enhancements to spent fuel pools at nuclear plants. Backup cooling power would be provided by solar panels and other unattended, high reliability electric generation. This could prevent spent fuel pool fires and radiation releases.
 
Our proposal has been submitted to the Nuclear Regulatory Commission in the form of a Petition for Rulemaking. PRM-50-96 is the only Petition for Rulemaking currently on the NRC docket for 2011. On May 6, the NRC published the petition in the Federal Register for comment:
 
http://www.nrc.gov/reading-rm/doc-collections/rulemaking-ruleforum/petitions-by-year/2011/
 
A blog moderated by the NRC is covering the status of the petition. Already, there are some very interesting public comments on the blog:
 
http://public-blog.nrc-gateway.gov/2011/04/22/the-nrc-were-ready-to-respond/
 
A full copy of the petition can be downloaded from:
 
                www.resilientsocieties.org
 
If people in your group would comment on the petition, either on the NRC blog or as a formal comment for NRC rulemaking, this would further the discussion about safety enhancements for spent fuel pools. The deadline for formal comments is July 20, 2011. Comments on the NRC blog before this date would be very helpful as well.
 
A notice on your website about the petition would be ideal, if you can do this and believe it would fit with your group’s goals.
 
Many thanks for considering this. If you have questions, please email thomasp@resilientsocieties.org or call at the number below.

Fukushima News: May 16th - 22nd

In a quick review of the last week's Fukushima global coverage, there was a modest burst in  global coverage at the beginning of the week, but it quickly dropped off as only international wire services were doing any coverage, and even coverage in Japan dropped of on Sunday. There is clearly many stories still being investigated from the quake primer to on Friday where TEPCo acknowledged that it is on the brink of economic failure.

Japan's TEPCO posts record loss as president resigns

From Yahoo News:

Japan's Tokyo Electric Power on Friday posted a record $15 billion loss and its under-fire president resigned to take responsibility for the worst nuclear crisis since Chernobyl 25 years ago.

The beleaguered utility posted an annual net loss of 1.247 trillion yen ($15 billion), the biggest ever for a non-financial Japanese firm. The company did not give an earnings forecast for the current financial year.

...

Recent TEPCO updates have confirmed experts' fears that fuel rods inside reactor one had been fully exposed to the air and had melted, and that reactors two and three were likely in a similar condition.

Five steps to prevent another Fukushima

From the Bulletin of the Atomic Scientists:

The situation at the Fukushima Daiichi nuclear plant has been an ongoing disaster since the March 11 earthquake and tsunami. According to an estimate by the Federation of Electric Power Companies of Japan, by April 27 approximately 55 percent of the fuel in reactor unit 1 had melted, along with 35 percent of the fuel in unit 2, and 30 percent of the fuel in unit 3; and overheated spent fuels in the storage pools of units 3 and 4 probably were also damaged. The accident has already surpassed the 1979 Three Mile Island accident in seriousness, and is comparable to the 1986 Chernobyl accident.

To prevent this kind of nuclear disaster from happening again, both the nuclear industry and government officials worldwide must seriously consider making at least five major changes to the safety systems at nuclear power plants, as well as to security measures and international agreements.

U.S. Was Warned on Vents Before Failure at Japan’s Plant

From the New York Times:

Five years before the crucial emergency vents at the Fukushima Daiichi nuclear plant were disabled by an accident they were supposed to help handle, engineers at a reactor in Minnesota warned American regulators about that very problem.

Anthony Sarrack, one of the two engineers, notified staff members at the Nuclear Regulatory Commission that the design of venting systems was seriously flawed at his reactor and others in the United States similar to the ones in Japan. He later left the industry in frustration because managers and regulators did not agree.

Mr. Sarrack said that the vents, which are supposed to relieve pressure at crippled plants and keep containment structures intact, should not be dependent on electric power and workers’ ability to operate critical valves because power might be cut in an emergency and workers might be incapacitated. Part of the reason the venting system in Japan failed — allowing disastrous hydrogen explosions — is that power to the plant was knocke
