  • nancy.. I'll bet if we approached the physics forum there would be a fine fit.. they are tryiing to figu
    re out just what we've done so they can do it

  • @fitter Nope. And I imagine it is. I'm a bit concerned about the working conditions, though. My skin doesn't react well to extreme heat and humidity, so I assume adding rads into it isn't going to help any. ;)

  • @Markfm Propaganda. "There's so much radiation that we are exposed to anyway, what's a little more?" As if adding to it doesn't make it worse.

  • @Markfm Way to reassure us, NYT...
    by radioguy 5/3/2011 3:30:04 PM

  • @dean Not like that one.... I only did it once for fun and we didn't go up more than 30 feet, but the ironworkers used to ride it all the time... you always knew the guys not to mess with by the ones that would ride the ball... OSHA takes all the fun out of the buisness.... but they would let torist Bungie jump off them... haven't seen any for awhile...would guess some of those when like your video....badly

  • @radioguy I would check the background of the author or who wrote it for them to post at NYT. :-) Sounds like a follow the money thing.

  • @radioguy you defently arenot an ironworker... someone has to hook the beams to hang off.. its actually very complex and requires a lot of skill to climb the steel... my guess thats were the saying "hanging by your balls" comes from

  • www.nytimes.com interesting link
    by dean 5/3/2011 3:34:07 PM

  • Well,any credibility the NYT had in this went out the window when they took the HUGE news, that Daiichi was now an INES Level 7, and rather than a 72pt headline reading "Worse than Chernobyl" theirs said something like "Japan Upgrades Nuclear Plant Status"... UNDER a story about Japan being so happy baseball is back. Epic fail.
    by radioguy 5/3/2011 3:36:07 PM

  • www.mext.go.jp another good link
    by dean 5/3/2011 3:36:43 PM

  • @Markfm, that is one dumb and callous article and certainly not according to what I expect from the NYT. One sin does not justify another. That about 10,000 people, equivalent of a small town, may have died of cancer because of above ground nuclear tests is regretable to say the least and no justification for deaths that may incur from ionizing radiation in the future however few they may be. The possibility of contaminated food is not even mentioned.
    by Peter Melzer 5/3/2011 3:39:04 PM

  • @radioguy, it is a shame They did not allow comments on this article. Who is behind this propaganda piece is a valid question.
    by Peter Melzer 5/3/2011 3:42:58 PM

  • @fitter Heh... my grandfather was a union steward in the Pittsburgh steel mills during their heyday, so I spent some time in the mills there during summers as a kid. Wildly exciting, but not something I aspired to. Though, in radio, I've always been the guy to climb up on the tower on top of a 27 story building to change the light bulbs, because I never felt that just the fact of height added any danger unless you let it. Of course, swaying in a light breeze hundreds of feet off the ground is a thrill too.

  • well all.. I better get to gym .. nice time today.. will be back later
    by dean 5/3/2011 3:43:44 PM

  • @all this is the flaw I mentioned about the RPV jumping up in a pressure issue. www.cnbc.com

    The Mark 1 reactors in the United States have undergone a variety of modifications since the initial concerns were raised. Among these, according to Mr. Lochbaum, were changes to the torus — a water-filled vessel encircling the primary containment vessel that is used to reduce pressure in the reactor. In early iterations, steam rushing from the primary vessel into the torus under high pressure could cause the vessel to jump off the floor.
    by Nancy 5/3/2011 3:45:08 PM

  • @radioguy I am sure your grandfather knows what "one hand for me and one hand for the company" means....
    by fitter 5/3/2011 3:45:36 PM

  • Does anyone know if a rush of pressure into the torus could twist or bow the torus piping? I have seen theories of pressure rush while the torus is too full of water could act like a water hammer.
    by Nancy 5/3/2011 3:46:03 PM

  • @Peter Melzer I've been mentioning the food, and said something like "OK, off to pick up a couple of cases of shelf-stable milk and a case of THIS year's California raisins. See you later" and someone said "o,h don't listen to him... he'll have you believing this thing is something else you have to worry about. They'd tell us if we should worry." I almost blew a gasket on the spot.
    by radioguy 5/3/2011 3:47:30 PM

  • @dean @radioguy what local did he belong to ..... you have to give those guys a lot of respect.... people think this shit just goes there and no big deal.... outside in mills in PGH the first hting you do in the winter is "not the ice off your stuff... have a freind up in PGH he alomst got killed when a ice chunk came down... he was OK after he changed, but his Pickup did't fair as while..
    by fitter 5/3/2011 3:49:00 PM

  • @Nancy Steam has a extremly high expansion rate.... it can do a tremendous amout of damage..... there is some speculation that was the Vapor cloud at 3 and I have a tendece to belive it was at least a contributing factor untill proven other wise
    by fitter 5/3/2011 3:51:54 PM

  • @fitter I don't know if I ever even knew that. It was years ago. OK...decades ago. He immigrated from Hungary and worked the mills till his death.
    by radioguy 5/3/2011 3:52:02 PM

  • @Nancy, think of the recoil owing to the upward-thrust explosion!
    by Peter Melzer 5/3/2011 4:01:36 PM

  • @radioguy the old timers have some great stories and they are true!!!!
    by fitter 5/3/2011 4:01:42 PM

  • I still keep thinking about that initial contraction in the R3 explosion. Hydrogen/Oxygen blended in the reactor building due to the venting, apparently in a volume robust enough to purge enough ambient air (~80% mitigating nitrogen) from the building so that the chemical combination into H20 created a vacuum enough to begin collapsing the building. What does that vacuum do to the pressurized and compromised containment? Add some negative pressure into the mix so the internal pressure on those pressurized structures inside (that are barely holding on) is even higher?
    by radioguy 5/3/2011 4:03:33 PM

  • @ALL Been away and catching up:

    1. The air filtration will not greatly reduce radiation levels inside the building, but will bring the airborne radioactivity down to a level where respirators can efficiently filter the air for the user. full face being 1000x www.google.com

    2. On 29 April, didn't wind change direction, not my area, but would change the levels in different directions (bo). This beast is still releaseing radioactivity.

    3. Dust masks do not provide any (significant) protection for radioactivity. Only well sealed HEPA provide the particulate protection needed. Combine with Charcoal filter for gasseous fission products.

    4. Marie, @1:59 this AM you said "I have to admit I didn't expect the numbers to be so...substantial", can you give me that link? or are you just talking about the new Limit 20 mSv?

    5. Crops (of different type, maybe weed) should continue in stricken areas. These can consume and concentrate radioactivity, including Cesium. And then be disposed of, not consumed.

    6. FHM is a Fuel Handling Machine. Crane operated service module for drawing in and discharging fuel.

    7. Fans with scrubbers means sucking air through HEPA filters that remove 99.97% of radioactive particulate.

  • Eventually, I keep coming back to Occam's Razor. The simplest, least convoluted explanation for both the rush of venting and the force of the explosion always comes down to some kind of flash criticality.
    by radioguy 5/3/2011 4:05:32 PM

  • @radioguy also have been working a little with dean on the cleaning systems and "only one article " that i could not link said the residule hear in the sludge will foster "hydrogen gas and nitous oside (explosive and flammable) the equipment sit on the nort side of the blding a floor above the invert of the reactor .... the tank is drawn as a flat top (not pressuere vessel) and the article states it requires venting.... we know venting has not been good for them Do not know how much sludge may have been in tank...

  • @RBean "2. On 29 April, didn't wind change direction, not my area, but would change the levels in different directions (bo). This beast is still releaseing radioactivity."


    There's a complete list of hourly wind changes that I posted just vbefore Panserbjorne9's stickied link last night.

  • @Ralph Unger, I like the sunflower idea, :).
    by Peter Melzer 5/3/2011 4:09:45 PM

  • @Peter Melzer Oh, where's that cute sunflower graphic from TEPCO when you need it?
    by radioguy 5/3/2011 4:10:32 PM

  • Pretty! But it is still just a way of moving the contamination, not removing it.
    by Ralph Unger 5/3/2011 4:10:36 PM

  • @RBean The link is posted above (NSC). It is the rad fallout models that they didn't want to release, but changed mind about. fwiw, marijuana is also an excellent soil cleaner ;-)

  • @Nancy I heard some discussion earlier about searchability of this scribble. I really appreciate this site, the work that you and everyone else has put into it, BUT, I feel like wer'e passing yellow stickies to one another, and sometimes pictures videos and charts. These all get stuck on the wall and are basically obliterated after 24 hrs or so. I admit, I am not very computer organized, but I am tired of saying to myself, "I know I read x, now where was it?" There was a posting that showed sample radioactivity (soil) at the same place as a 1 cm and 1 meter reading in Fuku, can you help me?
    by RBean 5/3/2011 4:11:05 PM

  • @marie rich And grows like a ...well...weed.

  • @radioguy "why is everyone fixated on the only "spark" can be criticality... there are many things that casuse sparkes.... and with an explosive invioment thats all you need to start a chain reaction... there is a lot of equipment and electric in the drywell....

    by Jim Carver 5/3/2011 4:13:07 PM

  • I'm not fixated on the "spark": that place had been destroyed. There were sparks everywhere. I'm fixated on the violence of that explosion vs the comparative foop of R1.
