if they do that underground wall they will have even more groundwater problems, because it will rise.

@Thunder hi and rest well

@ lilly.. I was thinking.. "if" we dig deep enough into North Anna with our research we may dig right into an active fault line... OOPS..

@dean LOL! :-) Elaine found this spiffy page at NRC last night. All event reports groups by NPP.

NRC has a huge data base if one looks around ,,, nice fine @ elaine

@ lilly ... read the first report listed for North Anna... interesting stuff

Procedurally required equipment consisting of a site dump truck specifically owned
and controlled by the licensee was not available and a portable generator was not
functional when tested.
by dean 9/4/2011 1:56:10 PM

The following CR’s were initiated during the first phase of the assessment:
• CR417940, IER L1-11-1, Fukushima Daiichi Nuclear Station Fuel Damage Caused
by Earthquake
• CR418070, SAMG Refresher Training Not Complete
• CR418115, Equipment required for B-5-B not available on site (88kW portable
generator failed)
• CR418290, Manual chain to open roll up door for warehouse does not work
• CR418339, Unit 2 penetration junction boxes not labeled
• CR418458, Identified during the B.5.b the following requirements for SEGTSC, “TSC
Response - Security Event Severe Accident Mitigation,” attachment 3, “Alternate
Instrumentation Methods”
• CR418515, Update procedures 0-PT-171.5 and SEGTSC
• CR418528, Deficiencies discovered during I&C B.5.b Walkdown of 0-PT-171.5,
“SEGOPS/SEGTSC Equipment Inspection,” Attachment 2, “Instrument and Controls
Equipment,”

The licensee identified the following vulnerabilities:
• Portions of the water and gaseous suppression systems and hose stations are not
seismically designed.
• B.5.b fire pump storage area is non-seismic.
• Potential leakage can occur through penetrations following seismic event.
• Seismically designed floodwalls are located in the non-seismic Turbine Building.
• Various isolation valves which would be used to isolate a flood source are located in
potentially flooded areas.
The licensee will evaluate the issues above in order to determine if additional mitigation
strategies are required.

This is the NRC letter discussed yesterday about public input on seismic reviews at US NPP
NRC SEEKS PUBLIC INPUT ON DRAFT GENERIC LETTER REGARDING
UPDATED SEISMIC ANALYSES FOR U.S. NUCLEAR REACTORS
The Nuclear Regulatory Commission staff is seeking public comments on a draft Generic
Letter that would require U.S. nuclear power plants to re-examine their sites’ seismic risk and
provide that information to the NRC.
Comments on the draft letter, published today in the Federal Register and available on
regulations.gov, will be accepted until Oct. 31. The draft letter will soon be available in the
agency’s electronic document database, ADAMS, by entering ML111710783 in the database’s
search engine. The staff expects to hold a public meeting on the draft letter in mid-October to
gather comments; meeting details will be announced separately in the next several weeks.
The letter represents the next step in the staff’s ongoing multi-year examination of
updated seismic hazard information for the eastern and central United States, through the NRC’s
Generic Issues program. This effort, labeled GI-199, began long before the events at the
Fukushima Dai-ichi nuclear plant in Japan and the recent Virginia earthquake. GI-199 was
prompted by the seismic analyses included in applications from 2003 related to new reactor
activity. The NRC issued an Information Notice in September 2010 regarding GI-199, including
the agency’s conclusion that existing plant designs safely account for possible earthquakes. The
notice is available in ADAMS by entering ML101970221 in the database’s search engine. More
information on GI-199 is available on the NRC website.
Interested parties can submit comments on the draft letter through regulations.gov, using
docket number NRC-2011-0201. Comments can also be submitted, referencing NRC-2011-
0201, by mail to Cindy Bladey, Chief, Rules, Announcements, and Directives Branch (RADB),
Division of Administrative Services, Office of Administration, Mail Stop: TWB-05-B01M, U.S.
Nuclear Regulatory Commission, Washington, DC 20555-0001. Comments via fax can be sent
to RADB at 301-492-3446.
The NRC staff will consider the comments before finalizing the Generic Letter, which the
staff expects to issue near the end of the year. The draft letter’s approach would have U.S.
nuclear power plants perform their analyses within either one or two years, depending on the
analysis method used, and deliver their results to the NRC. The agency will then determine
whether additional actions are necessary

I had stated earlier that safe shutdown equipment is naturally included in the seismic boundary however, equipment related to safety or important to safety are not as can be seen from these finding. That is the push I believe needs to be embraced and hopefully some of the efforts to switch to a deterministic approach will say that not only the safety system but all the supporting systems need to be included in being seismically qualified

I asked rockhopper about a tweet link and thisis her reply the link was
translate.google.com@ikrockhopper
@ElaineKirk The first box is about the news I tweeted tonight. Hosono said that the final disposal site should be outside of FKSM.
@ElaineKirk in order to 'share' the pain of FKSM. Many angry Ty about the comment now, like Why not TEPCO& gov share the pain w/ FKSM first!
@ElaineKirk The 2nd box is related to it, but a news one week ago. gov decided to allow debris and ash up to 100,000Bq to landfill
@ElaineKirk Before that debris &ash >8000 had to be stored, but no space for storage, and gov make the stupid decision.
by elainekirk 9/4/2011 2:03:44 PM

@ lily.. one thing that keeps getting missed.. they are not consistent in stating what the seismic requirement(s) are which must be followed and applied in the analyses and, the NRC leaves it up to the utility company to talk about what they did and how they did it... so there is lack of consistency... Seismic analyses approach runs accross the spectrum on how the analysis is done, what assumptions are made, ,which set of USGS seismic zone data is used etc..... unless they get consistent uniform requirements which must be analyzed using the same model etc,,, there will always be the subjectivity. .

The agency will then determine whether additional actions are necessary. "Their analyses".. opens it up to many many options.. and in my opinion the one used for specific plants will be close to what's been used in the past and what has seemed ok for NRC to stamp approval
by dean 9/4/2011 2:16:11 PM

This link posted further down really is scandalous. The PM's office had a report from NISA hours after the quake that showed exactly when and that fukushima reactors would melt down. So all the denials that anything was wrong were not incompetence.

@dean would a standardized review format help? What about having a 3rd party perform an additional review for the NRC?
by lillymunster 9/4/2011 2:17:33 PM

@ lilly, first off I think they need to define what method will be applied, there are many methods such as probabilistic, deterministic etc, each with varied approaches to complex analyses results... most of the time, if your the NPP owner you would want to drive the analyses based on the results which would determine how much money you need to put out to fix things. On the other hand we would want them to perform the most conservative seismic analysis which would most likely end up with many results that the NPP owner would challenging and say are not able to be done with out lots of cost or that don't apply to their facility. So there starts the game of negotiating and determining the minimum of what has to be done... a time line to do a graded approach (which lets the owner stretch things out over a long time) and finally a document which essentially
says we understand the risks but we will allow operation.
