Not all inspection has been done on unit 2 yet. Leak tests were 5 years ago for both units. #2 refueling they will leak test.

NRC asks if fans and gas treatment being inspected? Dominion claims other systems will detect problems.

Dominion - concluded we exceeded DBE. Getting systems back operable is goal. Schedule where we feel the plant will be. 9-16 final engineering evaluation done, 9-19 to 20 safeguard and tests not required and complete post event testing, startup assessment. Unit 2, 9-12 plan to have systems tested and inspected. 9-12 to 15 reactor dissasembly for refueling. 9-16 offload core and do visual inspections. 9-16 final technical evaluations to committee. 10-1 reload and 10-6 engineered testing and post even testing. Containment closeout. 10-13 ready for restart. NRC - unit 2 evaluations on 16th does that include fuel inspections. Dominion, no inspections would follow it. Engineering evaluations do not include fuel inspections.

NRC - were any core components declared inoperable? Dominion - did not declare any of those but plan on inspecting during refueling. All declared inoperable because of design basis.
NRC - refueling outage are you going to put new fuel in? Dominion - yes new fuel is on site, did visual inspection of it.
NRC - after #2 inspection findings would have to get put into refueling restart and new fuel.

Remembering "3/11": Six Months After the Fukushima Reactor Disaster, Key Lessons Appear To Be Going Unlearned. Regulatory, scientific and health experts agree: The "3/11" Fukushima reactor disaster is still ongoing six month later … and some major lessons are in danger of going unheeded.
Sunday marks the six-month anniversary of the Fukushima nuclear reactor crisis. In anticipation of that milestone, three leading U.S. experts held a news conference today to outline both what is now known in the wake of the Fukushima and where things stand for the nuclear power industry in the United States.
The news event speakers were: Peter Bradford, former member of the United States Nuclear Regulatory Commission, former chair of the New York and Maine utility regulatory commissions, and currently adjunct professor at Vermont Law School on "Nuclear Power and Public Policy"; Edwin Lyman, Ph.D., senior scientist, Global Security Program, Union of Concerned Scientists; and Dr. Andrew Kanter, national board president elect (2012), Physicians for Social Responsibility, and director of Medical Informatics/Health Info Services, Millennium Villages Project, Earth Institute, Columbia University.
The following eight concerns and lessons were among those outlined by the speakers: www.prnewswire.com

NRR engineer - asking about pipe testing spectral development. Dominion - evaluation would be long term only.
by lillymunster 9/8/2011 7:07:03 PM

NRC - do you plan to test pipe spectra analysis before restarting? Raising concerns about un-analyized incidents. Debate between dominion and engineer between visual vs. other inspections

by lillymunster 9/8/2011 7:08:15 PM

Dominion claims - no damage to more vulnerable items means entire plant is in good shape. Visual inspections are sufficient. Past design basis but plant can handle more (my synopsis of longer statement). Dominion wants to delay in depth piping inspections. Claims they are positively proving no damage. NRC questions this.
by lillymunster 9/8/2011 7:14:18 PM

Dominion Says installing field seismic and a battery back up to one recording system proves improvement at plant.
by lillymunster 9/8/2011 7:15:06 PM

Dominion claims reactors ready for restart and will ask for such.
by lillymunster 9/8/2011 7:15:51 PM

NRC - design basis accident should be infrequent, unique situation at NA. Not clear what we need from Dominion. Thorough evaluation will be done, a summary will not do. Just due to all the questions a series of meetings will be needed on this issue. The meetings will develop expectations for a document. Restart date same day as AIT exit, NRC will not be ready and dominion will not be ready by then either.

by lillymunster 9/8/2011 7:17:41 PM

Question public - wanting to know difference between safety and non safety side of the plant. Portions of plant only to standard building code such as water systems in non safety areas. - not answered, deferred question.

Question public - reluctance to do inspections of systems with less margin. Are you going to do those? Dominion - those are going to get done those are listed components to do.
by lillymunster 9/8/2011 7:19:54 PM

Question - long term actions installing monitors, instruments with power back up, site more confidence in kinemetrics rather than ingdal system,. IF no confidence in Ingdal system will you replace?
Dominion - the UPS power back up solves that. Will still rely on scratch plates
Question - equipment only in unit 1 - no equip in unit 2 so you rely on unit 1 for all seismic alarm.
Dominion - at higher elevations, hard to say if DBE or OBE is exceeded in other buildings. Will look at our seismic monitoring and maybe modern equipment. Systems with scratch plates are old.
by lillymunster 9/8/2011 7:22:58 PM

Question - license renewal, nothing about the licensee will consider during long term evaluations, the degraded cross section of properties will be considered for end of license period. Cross sections of properties of for example a pipe cross section and rates of what it would be like at end of license period. Wear rates for equipment and component thicknesses. How this will impact seismic rates, standards. You can't just walk through the plant, 90% will be "nice looking" but areas such as cross sections of things are important.
by lillymunster 9/8/2011 7:28:01 PM

Question - New equipment, what kind of spectrum analysis will you look for future equipment?
no answer, NRC closing statements. Lots of work going forward. Need to continue to dialogue and regulatory space and licensing documents. Lack of experience in this area. Figure out way through this correctly. Will have to do it in public forum. NRC will be sending people down to site.
Closing of the meeting!

@lillmunster Yes, thanks! I think Dominion should be applauded for being TRANSPARENT as much as they allowed anyway. (what do I know?) Encourage other power companies around the world to follow their behavior. Compare with TEPCO so that we can see the differences. Keep it light reading for the public (on SimplyInfo that is). My opinion. PR Newwire article was really good. Thx Majj www.prnewswire.com

@Cryptococcus it is good that both parties seemed to be trying to communicate. This is good and I hope in light of events in Fukushima this kind of openness becomes the norm. My impression after listening to the meeting was that Dominion thought they were going to get away with doing visual inspections and going right back to operating as is. The NRC and some of the public that attended made it clear where more inspection is needed and that the level of inspection Dominion has done so far isn't sufficient to know the true damage possible in the plant. I think the NRC set enough of a plan at the meeting that the process will be forced to be thorough as long as the NRC doesn't cave. They also brought up that this is an unusual event and should have much investigation and study right now so more people can learn about what happened. As in NRC and engineers. My thought was what would Dominion do if there was no oversight? I think they would have already restarted.

@lillymunster , I could watch only the first hour. I must say you did a fantastic job in keeping us abreast with this meeting. In respect, to the seismic issue I found it frightening that the operators did not have any idea how strong the quake shook the containment when they needed it most because at precisely that moment the seismic recorder had lost power. Even the alarms that would have indicated to the operators in the control room whether the magnitude of the shakes warranted a shutdown did not work. I believe this calamity could have been avoided, had an automatic trip been installed to begin with. In that case, the discussions about seismic design, strength and thresholds would have been had earlier, the seismic recorder would have required DC backup like at Fukushima, and a trip point would have been set accordingly. No need for second guessing on behalf of the guys in the control room.
by Peter 9/8/2011 10:13:24 PM

I meant an automatic seismic trip, of course.
by Peter 9/8/2011 10:16:45 PM

@Peter that was what I thought also, they need a seismic scram and some newer seismic equipment and in both reactors.
by lillymunster 9/8/2011 10:16:59 PM

@lillymunster , exactly. Furthermore, since, I could not watch that part, but it seems the operator mentions that they inspected the lake. Did anyone ask why its level fell by possibly two feet? Back later.
by Peter 9/8/2011 10:21:36 PM

@Peter no details on dam or lake inspection beyond they inspected the dam, no data.

Be back in a bit.
by lillymunster 9/8/2011 10:24:11 PM

@lillymunster was the North Anna Unit 2 shutdown for refuel planned before the quake? I thought the discussion about examining the Unit 2 fuel rods to check for quake related damage was interesting.

@all Weird question ...Am I the only one seeing this sight in German?
by smoss 9/8/2011 11:07:35 PM

@smoss yes. how odd

looks like the last bar on teppycam...
by Edano 9/8/2011 11:16:28 PM

Back to English now ....Very odd indeed
by smoss 9/8/2011 11:23:18 PM

lots of odd things this afternoon. My system locked up right after I saw that.

Hi all! Massive Southern California power outage..all of San Diego County, out into the desert, up to LA and down to the border. Freaky! I'm on my cell.
by Display Name:LM 9/8/2011 11:53:52 PM

@Display Name:LM the caiso webpage shows a big drop in power at about 3:40 pm www.caiso.com
by RonD 9/8/2011 11:59:49 PM

@RonD That's when everything went down. Still nothing.
by Display Name:LM 9/9/2011 12:06:56 AM

@Display Name:LM Was there a quake or just a massive blackout for no reason?
by lillymunster 9/9/2011 12:07:35 AM

@Lilly No quake as far as I know. Whole grid just went down. Power company is saying they don't know the cause.
by Display Name:LM 9/9/2011 12:09:30 AM

@lillymunster the radio news mentioned the power outage extends into arizona, don't think EQs are part of problem
by RonD 9/9/2011 12:10:05 AM

@RonD Wow! It's been warm today but less so than the last 2. Weird.
by Display Name:LM 9/9/2011 12:11:35 AM

@Display Name:LM suspect something in power grid had a glitch, but yep cooler today in SF area so I would not suspect power grid overload
