@lillymunster I'm thinking along the same line as you are! How could they function/work anywhere near the SFP holding these 32 MOX fuel rods, let alone safely load them into the reactor core w/o getting a lethal dose of gamma?

Antinuclear group to hold 1st of annual meetings in Fukushima mdn.mainichi.jp

"The Fukushima meeting will be attended by Matashichi Oishi, a former crew member of the Japanese trawler Fukuryu Maru No. 5, which was exposed to radiation from an American hydrogen bomb test at Bikini Atoll in 1954, a survivor of the 1986 Chernobyl accident and an antinuclear journalist, Satoshi Kamata."

Bo: note that word again, Fuku, in the name of the Japanese trawler exposed to the Bravo Test in 1954.

@smoss If the water provided enough shielding they are underwater the entire loading and unloading process. It seems odd that if it was giving off that much it wouldn't be setting things off. Still need to finish the cladding research. I have to wonder if the amounts of americium do anything to make the rods more unstable. Do you know anything so far about the properties of it? Would it increase any sort of reaction?

I excerpt verbatim from "Containment Structures" by M. Ragheb (04/19/2011) netfiles.uiuc.edu : “Several utilities and plant operators considered suing GE in the late 1980s after the disclosure of internal company documents dating to 1975 that suggested the containment designs were either insufficiently tested or had flaws that could compromise safety. The key concern was that the containment structure was undersized, and that a potential accident could overwhelm and rupture it.”

I forgot "suing GE". The first post attempt can be deleted.

@lillymunster Radiation dose to fuel handling workers is a greater consideration for transuranicbearing
fuels. Photon dose rates from unirradiated MOX fuel assemblies fabricated with
plutonium are significantly higher than those from UO2, but are manageable without
altering fuel handling equipment at the reactor site. Indeed, the fuel cladding provides
significant shielding against the lower-energy photons emitted by Pu-238 and, to a lesser
extent, those emitted by Am-241. Because of the higher photon energy source from Am-
241, it can be expected that a limit will be placed on the Am-241 concentration in the
MOX material at the fabrication facility. For example, the Am-241 concentration at the
French MELOX plant is limited to <3% Am-241/Pu to prevent excess radiation exposure
to workers.

OK, this article is just bizarre. Dozens of workers from Fukushima nuclear plant 'cannot be found': www.theaustralian.com.au

OK, more coherent information on this here: nuclearstreet.com

Lilly, I forgot to put a blank after the url. This time it should work.

I noticed something else in the scheme below of the Mark I containment provided in M. Ragheb's article ( netfiles.uiuc.edu ) i1214.photobucket.com . The layer of concrete under the wet well (torus) is much thinner than that under the dry well. If corium reached the wet well and melted through it, the distance to ground water is much reduced.

Radioactive suits improperly disposed

The Yomiuri Shimbun

FUKUSHIMA--Twelve protective suits and masks--including one suit on which a slight amount of radioactivity was detected--were found to have been improperly disposed of in Tamura, Fukushima Prefecture, which is located near the 30-kilometer exclusion zone of the Fukushima No. 1 nuclear power plant.

The Tamura city government received a report from a citizen on April 6 that the suits were abandoned at a site along National Highway Route 288.

Government officials found 10 suits, masks and gloves discarded on the ground that day. Two more suits were found disposed of April 12 and on Friday, respectively, at the same location. The government checked the amount of radioactivity and detected radioactive emissions at a level of about 4,000 counts per minute from one of the suits.

The NRC says it has upped its around the clock coverage at Fort Calhoun which is operated by the Omaha Public Power District. In addition to the two resident inspectors “three more inspectors and a branch chief” are now at the plant along with satellite phones for key workers and extra food and water.
by radioguy 6/23/2011 6:43:03 AM

So is that encouraging or discouraging?
by bo 6/23/2011 6:43:50 AM

@Bo, makes sense to me. Unable to locate workers and missing suits. Two months later we connect the dots. Seems to be the TEPCO way!
by Lurking 6/23/2011 6:44:48 AM

Pretty hard to tell. I think the revelation was supposed to indicate they're taking it seriously and "Oh, it's all under control. Perfectly safe."
by radioguy 6/23/2011 6:45:29 AM

@Lurking Every time they let some little devastating piece of info slip out, the mind always goes to, "oh dear, that's August's "deep regret"

If you don't mind I will probably be here a little more often. My other forum (at GLP) has been closed. The person moderating got tired of the onslaught of whackos and racists. It's nice to have people from around the world but with that comes the truly mentally ill!
by Lurking 6/23/2011 6:51:52 AM

@Lurking welcome in your new expanded form!
by bo 6/23/2011 6:53:56 AM

Thanks, I've been "lurking" for quite some time. I love the new group site. You guys have been quite active. I will miss my old "work group" but understand why the moderator found it was too much to keep up with. GLP does not allow anyone to "pass the torch".
by Lurking 6/23/2011 6:55:40 AM

I can offer data with backup links and have several "friends" with geigers around the country that take readings so we will at least notice spikes. My area (Southern Oregon) is .09-.11 uSv/hr) and lately readings are .13 - .17 uSv/hr.

@Lurking register? What do you mean?

Hi elaine, caffinate!!
by bo 6/23/2011 7:02:41 AM

@ Bo, sorry, I'm used to GLP and there you have to register or be just one of the herd.
by Lurking 6/23/2011 7:04:02 AM

@Lurking no prob. Post the data as it seems pertinent.
by bo 6/23/2011 7:04:36 AM

@Bo thanks, will keep doing what I have been doing then.
by Lurking 6/23/2011 7:06:24 AM

@bo missing workers.. Used to happen in US nuke industry 20+ years ago. Some of the best paying jobs were relatively short term and relatively high exposure. ID wasn't a big deal back then and changing name and company allowed the worker to Zero their exposure record.
