@borrrden Do you think the article is legitimate?by NHK Listener 4/13/2011 1:35:37 AM
@all, just curious, is there anything in particular that is located in Honshu ?by wtm 4/13/2011 1:36:34 AM
@NHK Listener You mean the picture? I don't see why not. It's not particularly technical. It literally says "Put cask in pool.....put fuel in cask....take cask out of pool" LOL...the only thing missing is "PROFIT!"by borrrden 4/13/2011 1:36:46 AM- @NHK, Borrden, you forgot...rool cask down side of hill into the ocean at night !! LOLby wtm 4/13/2011 1:37:54 AM
@borrrden I wonder how they will move those rods now, with buildings damaged?by FradyKat 4/13/2011 1:38:26 AM- @FradyKat, NHK Is there an article that goes along with this picture?by borrrden 4/13/2011 1:39:48 AM
@wtm - it's the biggest part island of Japan - so Tokyo?by UKVal 4/13/2011 1:40:35 AM- @FradyKat, veeeery carefully !!!!!by wtm 4/13/2011 1:40:39 AM
- @borrrden I have been trying to find out how they unload/upload the rods for 3 weeks. Still in the dark :(by FradyKat 4/13/2011 1:40:50 AM
- @wtm : ........... and make sure no earthquake is coming ......by edano 4/13/2011 1:40:58 AM
- @FradyKat I assumed they couldn't move them because the cranes are damaged....by borrrden 4/13/2011 1:41:48 AM
- @borrrden Yes, they have to repair the transport cranes first, but also ... fix concrete walls to make them water tight. It will take 2-3 years probably. But that gives them time to decay. I hope the water height is sufficient until then (for shielding).by FradyKat 4/13/2011 1:43:46 AM
- Actually the cleanup is going to be the most hazardous. If they do eventually get all the reactors under control months from now, the evacuations are lifted, and then they are moving the debris on top of those SFP's. One piece should break off and drop and hit a control rod and shatter it would be instant disaster !!by wtm 4/13/2011 1:43:57 AM
NEWS ADVISORY: Tokyo Electric president to hold news conference at 3 p.m. (10:43)by gabe 4/13/2011 1:46:03 AM
TEPCOS new super informative website is now live www.tepco.co.jpby elainekirk 4/13/2011 1:46:20 AM- @wtm Yes, many problems with the clean-up procedures. One pool has a crane in it. ANd many rods are already damaged. They may try to destroy the rods using acids or deionization or reverse osmosis.by FradyKat 4/13/2011 1:46:44 AM

- Oh I forgot that step is also listed. They are going to check the condition of the rods by using water analysis. The will grab some water with the big concrete truck arm through an opening caused by the explosion.by borrrden 4/13/2011 1:53:06 AM
Reactor pressure (Apr. 12 06:00)
(A) 0.416MPaG, (B) 0.908MPaG What's up with #1?by Salvador 4/13/2011 1:53:10 AM- @Salvador 0.908 would be a decrease from the 1.00X that I saw the other day ^^;by borrrden 4/13/2011 1:54:41 AM
- NEWS ADVISORY: Tokyo Electric president to hold news conference at 3 p.m.by NHK Listener 4/13/2011 1:54:56 AM
- @Borrrden, the 1.00x was the latest I have seen.by wtm 4/13/2011 1:55:20 AM
- Also the temp in the RPV is up too.by wtm 4/13/2011 1:55:43 AM
- Regardless, 0.9 or 1.0. it's waaay over specy. So what gives? Is the instrumentation damaged? Can't they vent? Why is the pressure inside risinf? Recriticallity?by Salvador 4/13/2011 1:56:44 AM
- @Salvador Do you know what the specs are ?by borrrden 4/13/2011 1:57:37 AM
- They are letting #1 core continue to rise a bit. Now nominally core runs at about 7000 kPa, but who knows what our can now handle. I believe drywell typical design point was order of 450 kPa, but #1 now leaks at under 200.by Markfm 4/13/2011 1:57:53 AM
- @borrden Didn't they say in the CINC conferences that specs were about 70+ atmospheres?by Salvador 4/13/2011 1:59:04 AM
- @NHK Listener, do you know if he has appeared before the press yet? Is this his first time?by bo 4/13/2011 1:59:52 AM
@Salvador I've been wondering about the venting, too. In the reports of the last venting, it sounded like they manually opened the cap on the torus to vent it.by radioguy edited by alblee 4/13/2011 1:59:53 AM- 1 MPa its not over stopped. Bwr operating core pressure is around 70 atmospheres, 1000 psi, 7000 kPa.by Markfm 4/13/2011 1:59:59 AM
- @Markfm I can confirm the 70 atm number as the amount of steam pressure sent to the turbine from the documentary I translated, I just wasn't sure about the inside of the reactor (would make sense I guess...)by borrrden 4/13/2011 2:01:02 AM
- @Salvador, you also have to remember that the entire inside of the RPV, the water nozzles and the sensors are now coated with a large coat of salt brine from the seawater injection. Per an article I saw the other day GE is estimating that there is 45 tons of salt total in all the reactors. That is causing water to not spray right, valves to not close, things to not seal correctly, and sensors to not register right !by wtm 4/13/2011 2:01:19 AM
@wtm do you happen to remember the date they started spraying sea water into #3?by Nancy 4/13/2011 2:02:07 AM- Safety margin on the design should be factor of 3 or more, but everything has been pounded by quakes and explosions, original paper design is kind of meaningless.by Markfm 4/13/2011 2:02:14 AM
- @wtm takes up a lot of space too.by radioguy 4/13/2011 2:02:16 AM
- @radioguy, holds heat also.by wtm 4/13/2011 2:02:41 AM
- @Nancy, i will pull up a JAIF and see if it is on there ?by wtm 4/13/2011 2:03:16 AM
- Multiple public references to the operating pressure, consistent.by Markfm 4/13/2011 2:03:23 AM
- the 12thby radioguy 4/13/2011 2:03:23 AM
@all i thought of something today, I said hey, this couldn't get much worse. But then I thought typhoon season is just around the corner.by Jim Carver 4/13/2011 2:03:45 AM- by radioguy 4/13/2011 2:04:07 AM
