Twitter from Rockhopper: The fksm worker assumes that zirconium covering fuels are still melting, this is a reason of high H in the pipes.

Referring to the new news that they are finding hydrogen in unit 1 pipes

interesting piece that Virve posted,, from the table I see higher spina bifida numbers accross the board, no major predominance to male over female, .... at this point I wonder what percentage of the initial exposures through JAPAN have risen to it's peak and now is tapering off such that it is not a chronic ongoing exposure problem
by dean 9/23/2011 2:01:07 PM

@ lilly.. there is also the possibility that the H2 in the pipes could have been there from earlier because of how the piping systems have high points etc.

ENTRAPPED HYDROGEN EXAMPLE
by dean 9/23/2011 2:06:51 PM

@dean Is this common, the hydrogen trapped in pipes? TEPCO was dodgy about exactly how much is in either the pipe or the system. They also can't keep nitrogen in the containment for obvious reasons but they keep injecting it.
by lillymunster 9/23/2011 2:11:11 PM

@ LILLY, at the fuku I would say it's very possible since so much was produced, every system should be monitored some how or flushed before cutting into piping to prevent the same thing as video

@dean, good morning. Rockhopper's mention of ongoing hydrogen production reminds me of this entry in tab. V-2-1 of the Roadmap to Restoration ( www.meti.go.jp ) : "Although most of the fuel rods in the SFPs are assumed to be undamaged, some of them might be damaged or deformed by debris and other contaminants in the pools. Also, seawater has been injected into the SFPs of Units 2 to 4."
by Peter 9/23/2011 2:23:00 PM

ty Peter and good morning, by the way I replied to your email on the google and am set up.... I look at the SFP s having a tube of those pick up sticks dropped over it and now the delicate part of retrieving every stick off without causing further nuclear incidents

A few weeks ago elaine found an accident in a Japanese npp, where hydrogen got trapped in a bend of a pipe connected to the Residual Heat Remover. An explosion was sparked by the sudden pressure change in the pipe when the operator tested the remover during a shutdown.

@dean , as to the google+ thing I am all naive about it, but thought it may be a useful tool to get in touch and perhaps have group conversations if we find it helpful. I saw lilly on it as well.
by Peter 9/23/2011 2:29:50 PM

precisely the risk of piping runs where entrapped gas can be held
by dean 9/23/2011 2:29:55 PM

yes.. agree @ Peter, I put our folks on the top 10 list
by dean 9/23/2011 2:31:54 PM

not sure how it works but I'll bet lilly and elaine can train us..
by dean 9/23/2011 2:32:14 PM

I need to take off to work .. but will come on line there..
by dean 9/23/2011 2:32:51 PM

@Peter I am still working on connecting everyone in Google +. I think they opened it up to more people this week. I need to mess with it more but I think it could be a good connection tool as it is less fluid than scribble.
by lillymunster 9/23/2011 2:37:08 PM

On the subject of recurring hydrogen explosions in commercial nuclear reactors, I cite from www.oecd-nea.org : "...,hydrogen detonations within BWR piping have been reported by several stations. In some cases the immediate consequence was loss of emergency core cooling system (ECCS) train (i.e. the high pressure injection system). The direct cause is the ignition of hydrogen following its separation from oxygen due to the radiolysis of reactor water. In another instance there was unisolable blowdown of steam to the suppression pool. Similar events had been reported as far back as 1985."
by Peter 9/23/2011 2:40:46 PM

@lillymunster , I read about it on CNN. Google+ is open to the public now. They mention a capability for group conferencing. That would be good. But as I said I am totally naive about it.
by Peter 9/23/2011 2:44:35 PM

@lillymunster, I also find it notable that tepco is still attempting to inert the PCVs despite the holes they must have. The possibility of another explosion seems very real to them.
by Peter 9/23/2011 2:50:21 PM

@Peter that was my take on it, there must be a real enough risk to justify putting nitrogen in repeatedly as it leaks out.
by lillymunster 9/23/2011 2:56:33 PM

by elainekirk 9/23/2011 2:59:49 PM

I agree about Google+. It's still under development but will eventually become a very strong tool for conferencing, possibly making use of some of the tools formerly available at the extinct Google Wave. We'll see how the platform evolves.

[OFFTOPIC]
Will this affect our understanding of the Laws of Physics?

Neutrinos may travel at speeds faster than the postulated, and so far observed,
cosmic limit of the speed of light.

@ Pedro, there is also cerenkov radiation or blue glow emitted from radioactive material in water where the particles travel faster than light in water...
by dean 9/23/2011 4:09:46 PM

equal studies need to be made on measurement of the speed of light and other fast particles in different mediums such as water or air or vacumn etc. to reconfirm assumed speeds.

Hi@all, is this the kind of magnesium Dr. Busby uses? Antitoxic features of magnesium oxide under combined radiation and thermal injury www.ncbi.nlm.nih.gov
by Liz 9/23/2011 4:23:13 PM

@Liz Busby doesn't specify the type of magnesium. I couldn't get the link to work

by Liz 9/23/2011 4:28:54 PM

@Liz Thanks! Will see if I can find the total text of that. I looked up Magnesium Oxide. It is what is used in some laxatives. If that is in Busby's supplements it should come with a commercial sized box of toilet paper. :-)

Skin contamination

Sites of contamination should be washed or scrubbed gently using warm water, soap and a soft nail brush. Do not break the surface of the skin or allow contamination to enter the blood stream. This is the significance of gentle scrubbing using nothing more abrasive than a soft nail brush. Uncontaminated cuts or sores should be covered with a waterproof dressing prior to washing. Washing can be carried out over an ordinary sink. Extensive skin contamination should be removed by washing in a shower.

Persistent skin contamination, i.e. that which cannot be removed as above, may be removed by a chemical decontamination procedure as follows: a 4% solution of potassium permanganate can be applied to the contaminated area and allowed to dry. The resultant brown staining may then be removed with a 5% solution of sodium metabisulphite.

www.nottingham.ac.uk good article from UK
by dean 9/23/2011 4:41:08 PM

@ illly I've used potassium permanganate which usually turns a purple to dark brown... then left for a few minutes followed by the sodium metabisulphite... it removes more stubborn skin contaminations
by dean 9/23/2011 4:42:30 PM

@dean Light doesn't travel at the same speed regardless of the medium. The significance of this new finding (which had been suspected by other CERN experiences since at least the early 90's) is that, if confirmed, neutrinos may travel faster than photons in the vacuum, which would pose severe problems to Einstein's theories and, therefore, all the modern understanding of physics. It would bring the necessity of a new paradigm. The repercussions are deep and dramatic.
by Pedro Jesus 9/23/2011 4:46:07 PM

this is nothing more than one measuring. there have been thousands of neutrino speed measurings before and they never travelled faster than light. maybe they measured the distance between rome and geneve wrong. :)
by Edano 9/23/2011 4:48:51 PM

@lillymunster , liz, since magnesium oxide is supposed to act as an ENTEROSORBENT, I found this info on another enterosorbent and what it exactly does: www.sbras.nsc.ru
by Peter 9/23/2011 4:50:21 PM

i used to be at the controls of the reactor and jerk.. then say.. I just got hit by a neutrino...
by dean 9/23/2011 4:50:22 PM

I've read a few article about the neutrino and speed of light finding. Most of them are more skeptical than the CERN message. I'm not a physicist but if I had to choose between 2 options. Option 1, the laws of physics understanding of the speed of light is incomplete or incorrect at some important level. Option 2, the laws of physics understanding of neutrinos is incomplete and this causes the apparent violation of the speed of light. I'd bet on #2. Time will tell. news.yahoo.com

well all.. I need to go for now... @ Peter much will remain as the new fields of physics open up... I travel on sunday for work and will be on more I hope.. will be on later today ... be well and peace to all
