Evaluation from the Fukushima Task Force Review ( www.nrc.gov , p 40):“Eventually, all BWR facilities (in the US, ed.) with Mark I containment designs voluntarily installed a hardened vent. No regulatory requirement was imposed. The designs of those vents varied from plant to plant. At some facilities, the hardened vent relied on ac-operated valves, some relied on dc-operated or air-operated valves, and some incorporated passive rupture disks along with isolation valves. Each different design has different operational complexities during a prolonged SBO scenario. The updated final safety analysis report for each facility includes a description of the hardened vent, but the vent is not a required design feature for that facility.
In BWRs with a Mark II containment design, the containment volume could be approximately
25 percent larger than the volume of Mark I containments. In the resolution of GSI157,
“Containment Performance,” the staff concluded that that the need for hardened vents at
BWRs with Mark II containments should be evaluated on a plant-specific basis through the
IPE program. Eight BWR units in the United States have Mark II containment designs. Three
of these units have installed hardened vents, and the remaining five units at three sites have
not installed hardened vents.”

Good morning, Dean. Reading the task force recommendations, I had the idea that a radiological emergency fund should be created to which all nuclear power plant operators contribute. Safety upgrades are discounted such that the owners of the most improved plants pay the least. How about that idea?

greetings to you Peter,,, good seeing you

@Mona Hope your still around. If you have a smart phone you can check the scribble page on your mobile phone browser. I know it views properly on iphone and android. Just use the same web address to get to the page.

I hadn't tried checking the audio on that video of the worker. I did grab some still shots. The object he has in his hand he initially holds in two hands like it is a handheld computer. One side is white and the other dark. That made me think it was some sort of smartphone or handheld computer.

that sounds like excellent INCENTIVE @ Peter,, I'm going to start commenting so at least I can say my voice is heard.

I know the commercial NPP OWNERS and operator are alittle gun shy about pooling money due to the loss of billions over the whole YUKA mountain fiasco

did that work?
by dean 9/3/2011 12:36:23 PM

all those posts come from signing up to receive updates from the NRC. there sure are alot of new assignments of "RESIDENT INSPECTORS" at power plants
by dean 9/3/2011 12:37:09 PM

@dean nope, said I needed permission and tried to open a google doc. Is it in an email you got from NRC?
by lillymunster 9/3/2011 12:38:36 PM

yes.. through gmail.com
by dean 9/3/2011 12:40:35 PM

Dean if there is a link in the email for more information or to view it online
try opening that link in a new tab

@dean ok, it jumped to 2002 for some reason, here is the direct link to 2011. www.nrc.gov

Do you know what document listed is the one asking for public comment? Do you remember what email service you signed up for with NRC? They have Lyris and the main gov email service www.nrc.gov

@Peter "In the control room, a 1970s-era seismic detector failed to record data for a critical eight seconds when primary power went down, slowing the company’s analysis. The company has added a battery backup to the unit to prevent a recurrence."

Sounds like they are operating under the TEPCO plant upgrades plan.

peter and lilly have you seen that link I put in which showed the news article of the protests made by a group about building North Anna on a known fault line and in fact, it was reported that construction had to halt while there was some rock slides in the construction site...
by dean 9/3/2011 12:52:37 PM

@dean if you want to forward the email in question I can see if I can extract the web address if there is one in it.
by lillymunster 9/3/2011 12:52:38 PM

ok lilly
by dean 9/3/2011 12:52:53 PM

@dean Not sure if I saw the post. I went through posts right after the quake that had a bunch of congressional testimony etc about N Anna and the events around the building & licensing. I don't think I had anything on protests.
by lillymunster 9/3/2011 12:53:48 PM

done @ lilly

NRC ISSUES SECOND OF THREE TECHNICAL EVALUATION REPORTS ON
DOE’S YUCCA MOUNTAIN LICENSE APPLICATION
The Nuclear Regulatory Commission has published the second of three technical
evaluation reports (TERs) detailing the agency staff’s review of the Department of Energy’s
license application for a high-level waste repository at Yucca Mountain in Nevada.
Publication of the report provides the staff’s technical review of the pre-closure
information in the Yucca Mountain application. This TER does not include findings as to
whether NRC’s regulatory requirements have been satisfied.
“Technical Evaluation Report on the Content of the U.S. Department of Energy’s Yucca
Mountain Repository License Application; Preclosure Volume: Repository Safety Before
Permanent Closure,” is part of the agency’s orderly closeout of the Yucca Mountain license
review process and is intended as a public record of the staff’s scientific and technical work in
preparing for and reviewing the application. It was developed using the draft Volume 2 of the
staff’s Safety Evaluation Report (SER) on the application.
A TER on postclosure safety, based on what would have been Volume 3 of the SER, was
issued publicly on July 21. (Volume 1 of the SER was published in August 2010, before the
licensing review was stopped.) The TERs were prepared as part of the agency’s knowledge
management activities during the closeout of the Yucca Mountain licensing review. The
closeout, including publication of the third TER, is expected to be complete by Sept. 30.
The TER is available on the NRC website’s Yucca Mountain page.

Hay guys, here's my Unit 3 analysis, featured @ lewrockwell.com Note especially the animation in Figure 6, that is the model. Gotta head out now, but back in a few hours.
by Ian 9/3/2011 1:05:09 PM

@lillymunster , I guess that is why the inspectors are visiting. The WP gallery provides a great impression of the damage in the region. I still have difficulty believing the extent, because the magnitude was not that great: www.washingtonpost.com .
@Dean, I missed the rock slide, but the Task Force review shows that the NRC did not dig too deep on the seismic issue in the 1970s. In retrospect, they blame it on the lack of knowledge at the time. But it remains unexplained why they did not re-start review with increasing knowledge base. In addition to knowledge about geology and seismicity, the technology of sensors must have progressed and more improved automatic seismic scrams may be implementable today than were available when the NRC visited the issue last with the result that such provisions were not worth the money. The task force speaks of only one plant in the US today with automatic seismic scram capability: Diablo Canyon.

ty Ian,,, great animation
by dean 9/3/2011 1:09:57 PM

@Peter Melzer I think the rock slide is the same incident sometimes described as the excavation that collapsed. The hole due for unit 1 had one of the side walls collapse showing how unstable the earth in the area is. Nobody did anything.
