some how I got in modby dean 6/23/2011 11:35:52 PM
can't remember what RBM stands for...by Dean 6/23/2011 11:36:13 PM- I would say.. cont rod drft alarm signifies movement in the control rodsby Dean 6/23/2011 11:36:20 PM
- I see the seismic trips.. I am alittle surprised to see the time difference between them tho... and i'm not sure what logic they use for their safety system ,, Ie: 2/4 or 3/4...by Dean 6/23/2011 11:36:27 PM
- @Edano.. it says all CR full in but that seems to have occured rapidly , usually the safety rods go in quickly but the control rods have to drive in and it takes minutesl ong to do thatby dean 6/23/2011 11:39:12 PM
- and there is low water level in rpv. does it indicate a leak from earthquake ?by Edano 6/23/2011 11:40:27 PM
OPPD helicopter makes emergency landing 1.5miles from NPP www.ketv.comby lillymunster 6/23/2011 11:43:38 PM- @Edano.. I think when a typical scram occurs depending on the type of scram, automatic features kick in and the level in the vessel and supression pool go through a transient condition before stabilizing so maybe we are seeing those early built in parameters reactionsby dean 6/23/2011 11:43:46 PM
- I think that at the seismic trip there were some damages to piping etc which did result in leaks so the system would be trying to overcome that leak with adding more water to balance water levels at the same time trying to deal with increased steam pressuresby dean 6/23/2011 11:45:02 PM
@Dean - The system was reacting to the trips in 10 ms, but there was a 12 sec. gap between seismic sensor detection "C" and "B" it seems.by Rob in SF 6/23/2011 11:45:05 PM- yes Rob.. that does surprise me, they usually are all set at the same pointby dean 6/23/2011 11:48:26 PM
- where I worked they would have all (3 channels) were in close proximity and would have instanty tripped when that strong of an earthquake hitby dean 6/23/2011 11:49:05 PM
- www.ketv.com @lilly the news article.. I wish we could get the media attention to the fact that cooper is being run (for profit) by a different group and are driven to keep that money flowing inby dean 6/23/2011 11:49:55 PM
- @dean There are lots of references online, just need to somehow make it part of the issue on more people's viewby lillymunster 6/23/2011 11:52:58 PM
- yes @lilly.. perhaps quotes from the pres & ceo for CALHOUN and then COOPER.. perhaps finding some contract that cooper plant has for the performance incentives etc..by dean 6/23/2011 11:54:14 PM

RBM is the rod block monitor, an approx. 8' tall and approx.4' wide system that's supposed to be part of the recirc system. Nancy, it's in your website! LOL Look in top right hand corner. You are the bomb :) It's in the GE Mark 4 manual.

- TEPCO hopes to resume water decontamination
The operator of the crippled Fukushima Daiichi nuclear power plant hopes to resume the water decontamination process at the plant within several days.
At the nuclear power plant, a water treatment system started operation last Friday, but it ceased functioning after only 5 hours due to a sharp rise in radiation levels in US-made equipment built to absorb radioactive material.
Tokyo Electric Power Company hopes to restart the system and continue the decontamination process by pouring low levels of contaminated water into the equipment to decrease radiation levels.
The decontamination process has been halted several times due to a series of problems.

www3.nhk.or.jpby Edano 6/24/2011 12:18:40 AM - High level of radiation exposure estimated
A group of doctors has found that the estimated level of accumulated internal radiation exposure for people living in Fukushima Prefecture has exceeded 3 millisieverts.
The researchers, including doctors who have provided medical care to A-bomb survivors, conducted analysis on the food and urine of 15 residents in Iitate Village and Kawamata Town in Fukushima Prefecture. These areas are about 40 kilometers from the Fukushima Daiichi nuclear power plant.
They estimate that residents have been internally exposed to up to 3.2 millisieverts for about 2 months, measuring from the date of the accident in March until early May.
Three millisieverts is 3 times higher than the long-term annual limit for ordinary people recommended by the International Commission on Radiological Protection.
One of the researchers, Nanao Kamada, says people should refrain from eating vegetables grown in the area where high levels of radiation have been detected.

www3.nhk.or.jpby Edano 6/24/2011 12:19:38 AM - Parents concerned about children's radiation
Parents and teachers in Fukushima Prefecture are skeptical about the government-set level of exposure to radiation for children, especially in relation to outdoor activities. They fear children's health may be affected by radioactive contamination from the Fukushima Daiichi nuclear power plant.
The education ministry released a report to the Nuclear Safety Commission on Thursday concerning school yards at 55 locations where high levels of radiation had been detected. It also reported that after the top soil was removed at 41 locations, the radiation level dropped to 0.5 microsieverts per hour on average.
The report also said that all locations had radiation levels under the government-set 3.8 microsieverts per hour. The ministry has said that schools where this level is met can restart children's outdoor activities.
But many parents and teachers in the prefecture are skeptical about the standard set by the ministry.
They say exposure of 3.8 microsieverts per hour is too high compared to the long-term reference level recommended by the International Commission on Radiological Protection.
All schools continue to refrain from outdoor activities or limit them to 1 to 3 hours per day.
The Nuclear Safety Commission member Seiji Shiroya says the standard should not be set unilaterally and that it should be established at a level all, including the parents, can accept.

Hey, thaey finally got the Crane out, that felll into the reactor in FUKUIby Veenie 6/24/2011 12:27:34 AM
@Veenie unbelievable now they will start that one up ...by Elaine Kirk 6/24/2011 12:28:58 AM- @edano those numbers of exposure are significant are they not!! @veenie is it tweetie time?by Elaine Kirk 6/24/2011 12:30:36 AM

- @Veenie your empire bio still says you learning how it works -looking at your growth I think you know how it works www.empireavenue.comby Elaine Kirk 6/24/2011 12:39:53 AM
- This is from a report written in 2001: "Reactivity coefficients of MOX fuel are more negative possibly causing variations in power output, which
could result in a reduced margin for the shutdown of the reactor in an accident. These issues are likely to increase the speed with which an accident evolves and increase the severity of an accident." So some people knew what happened at 3 could happen.by lillymunster 6/24/2011 12:42:16 AM - @Elaine Kirk I haven't done a thing on it since tuesday am ?.....Remeber my AC went out.....good almost tripled without work ))by Veenie 6/24/2011 12:46:16 AM
