TEPCO removing information from their website (translated) translate.google.com

Conflicting Stories Surround Fukushima Fuel Pool #4 :
" On the one hand, Union of Concerned Scientists and the Nuclear Regulatory Commission claim that fuel pool #4 is dry and that zirconium fires have taken place, releasing cesium and iodine to the environment. On the other hand, TEPCO says the #4 fuel pool has water. Who's right? The NRC is right, if the fuel pool had a leak and water drained out. But if the steel liner and concrete walls remained intact, TEPCO is right and there is time to bring the #4 pool situation under control. " www.huffingtonpost.com

@Reed marie rich posted this tonight, and while it answered some questions, it left more unanswered.
by radioguy 4/18/2011 12:54:04 AM

@radioguy hmm. why did 4 have so many unirradiated rods? I thought new rods didn't have to be in a pool unless they were mox? 3 also had a well documented fuel change in Aug. 2010 where they put mox in. Shouldn't that have generated new "old" rods for the SFP in Aug 2010. Things are not adding up.
by Nancy 4/18/2011 1:00:00 AM

Why does 4 have such a big stockpile?
by Nancy 4/18/2011 1:00:29 AM

@Nancy because the core was emptied for maintenance, leaving all the fuel in the SFP
by Sims 4/18/2011 1:01:29 AM

@Nancy That's been my question since the first JAIF report, along with the light load in the R1 SFP.

R4 had been unloaded, 546 assemblies, added to the 548 in the pool cooling is 1196. There are a couple hundred spare. Now we see it's because of the 200 unirradiated assemblies being stored there.
by radioguy 4/18/2011 1:02:25 AM

Why aren't TEPCO pumping the radioactive brew into a tanker as a temporary reservoir? It would be able to take huge amounts. Via large RO units, the water could be largely decontaminated (filters even solubles, except for Tritium). So even if this takes time, it could be done that way and pumped back into the ocean. Why does the Japanes government allow TEPCO to contaminate at this level, while fining small businesses for polluting as much as one cubic foot of waste water?
by T&M 4/18/2011 1:02:59 AM

@radioguy They don't swap out all the fuel rods when yhey refuel. It's done in the states roughly in thirds
by marie rich 4/18/2011 1:03:31 AM

R1, had been reported as 200 cooling rods in SFP, and 400 in R1. So they had emptied 200 from the SFP to make room for a tradeout the very month of the disaster.
by radioguy 4/18/2011 1:03:38 AM

hence the unirradiated rods
by radioguy 4/18/2011 1:04:09 AM

They were trading out 100
by radioguy 4/18/2011 1:04:23 AM

leaving empty space to take the 100 our of the reactor, and the unirradiated ones to replace.
by radioguy 4/18/2011 1:04:56 AM

think so. Then the question becomes why? right before it was to be retired?
by marie rich 4/18/2011 1:04:59 AM

So, um... what to make of the R3 numbers??
by radioguy 4/18/2011 1:05:13 AM

Maybe they expected to get an extension....
by marie rich 4/18/2011 1:05:25 AM

Waht arte those 52 unirradiated assemblies in R3 SFP?
by radioguy 4/18/2011 1:05:39 AM

What kind of fuel?
by radioguy 4/18/2011 1:05:58 AM

If mox, they have to be stored in water. If regular uranium (is that an oxymoron?) they were getting <can't remember the real ter> aclimated for use
by marie rich 4/18/2011 1:07:28 AM

It was explained to me ny a guy who was once in charge of preparing the bundles (note: in USA), Fuel rods are delivered to the fuel handling bldg. They aren't hot so are stored in one half of facility in racks. Nearing refuel time, they are moved into SFP to *whatever it's called* and be ready to be fissile. Then moved into reactor at refueling outage
by marie rich 4/18/2011 1:10:40 AM

@marie rich : in japan they use to swap the entire fuel load. in the u.s. only a third.
by Edano 4/18/2011 1:15:34 AM

@radioguy If I had my info right there were two shipments of MOX 32 and 64 to Fukushima. I don't know where they all are at, if they are in the reactor or some in the SFP.
by Nancy 4/18/2011 1:18:23 AM

@Nancy : 32 are in rpv #3.
by Edano 4/18/2011 1:21:49 AM

I didn't realize the sheer number in the reactor. They are counting rods not assemblies though, that would make more sense. #1 still bugs me. Too many things don't seem right.
by Nancy 4/18/2011 1:21:58 AM

@Edano so if the numbers I had were right then the 64 are still somewhere.
by Nancy 4/18/2011 1:22:24 AM

@Nancy : wikipedia says 32 out of the 548 in rpv #3 are mox. no word of the other 64.
by Edano 4/18/2011 1:24:00 AM

@Nancy No, those are assemblies.
by radioguy 4/18/2011 1:27:49 AM

@you Unless it's a translation error, it's been consistent in the JAIF reports.
by radioguy 4/18/2011 1:28:27 AM

7 hours without eq in japan.
by Edano 4/18/2011 1:31:09 AM

@Edano That's scary, actually. They'd been getting faster.

[Ditto... Just imagine if another 8+ hits one more time at this stage when everybody is working frantically and in apparent disarray at Ground Zero and another beyond design tsunami repeats... ugh... - Alblee]

@Alblee At this point the quake would be worrisome enough...

[Yeah, @radioguy, all those loose thingamajigs getting rejiggled and other thingamagloogs at snapping point finally snapping off... - Alblee]

they had a 5 hour break yesterday as well.
by Edano 4/18/2011 1:34:34 AM

@Edano They must hold their breaths during the lulls by this time.
by radioguy 4/18/2011 1:36:19 AM

We had an EG within the last hours.
by NiteSpawn 4/18/2011 1:37:50 AM

half an hour after the big 9er one they had an 8+ so now there should be only some 7+ to be expected.
by Edano 4/18/2011 1:39:12 AM

@Edano If it's an aftershock, that's true, but these continuous quakes in Japan are pushing the definition of aftershock.

In the dearth of news at the moment, some leaks out of North Korea, as reported by Kyodo:

"North Korea's state television has reported the seriousness of continued radioactive leakages at a Japanese nuclear power plant hit by the March 11 earthquake and tsunami that devastated northeastern Japan.

In a Korean Central Television Station program broadcast Sunday night, experts voiced concern about the situation at the Fukushima Daiichi power plant.

''What is most serious is that even a month after the accident, we see no prospects of getting radioactive leakages under control,'' an expert said.
