Ross, RE: Did you ever get a clear insight into how/why they got 1 or 2 EDG’s back but not the others? (e.g. Insights on essential cooling / alternate EDG cooling)

No… there is very little that is truly clear with these events… I heard (rumors) that the service water/UHS -cooling to EDGs and various pumps was knocked out by the tsunami. But no real “facts” or absolute confirmation. Looking at the over head photos perhaps units 5 & 6 did not lose SW or they could get it back… but again speculation why one of their EDGs continued to work. Also heard that they had above ground EDG fuel tanks, some which were washed away. Electrical buses getting flooded/ wetted with seawater…. But again.., no facts… rumors.

Sorry. You will just have to be patient. The information will come.

Dave Garmon is our IOEB point of contact for the IFR / OpE COMM updates related to the Japan event. His cubicle is right across from your office Ross… please give him your questions/ any follow-up concerns as he has the follow-up tasking on the Japan events. The NRC is committing to a 90 day review and a longer term by year end review, and I’m sure some very long term studies of these events, not doubt.

From today’s daily news summary –

NRC To Launch Two-Step Review Of US Nuclear Reactors. On the heels of the nuclear crisis in Japan, the AP (3/24, Daly) reports the Nuclear Regulatory Commission voted Wednesday to launch a “twostep review” of the US nuclear plant fleet. The NRC will select a “task force, made up of senior staff and former NRC experts,” to conduct “short-term and long-term analyses of lessons learned from Japan.,” and how those lessons can be applied to the US nuclear industry. The short-term review is to be completed “within three months,” while the longer review should be wrapped up by the end of the year.

USA Today (3/23, Winter, 1.83M) noted briefly the NRC’s news release on the “task force” to analyze “the lessons that can be learned from the situation in Japan.” NRC Chairman Gregory Jaczko said, ‘We will perform a systematic and methodical review to see if there are changes that should be made to our programs and regulations to ensure protection of public health and safety.”

AFP (3/24) notes Chairman Jaczko said, “Examining all the available information from Japan is essential to understanding the event’s implications for the United States.” NRC Executive Director for Operations Bill Borchardt said the work will “help determine if any additional NRC responses, such as orders requiring immediate action by US plants, are called for.”

CNN (3/24) said the “review will supplement existing programs to ensure plant safety,” while Reuters (3/24, Rascoe, Rampton) reports that Jaczko said in a memo to Borchardt that the task force efforts “should be informed by some stakeholder input but should be independent of industry efforts.” NPR (3/24, Peralta) also covered the announcement briefly.

WKRG-TVi Mobile, AL (3/23, 10:15 p.m. CT, 46,956) broadcast that “the Nuclear Regulatory Commission has launched a two-step review of the 104 plants across the country.” WKRG adds that “a short-term review is to be completed within three months, with updates after 30 days and 60 days. The longer review should be completed by the end of the year.”
