@Deidre yes ty. Read 3 times and went back read again- just got more confused.

@Alblee more confusion/conflicting info- But more radiation headaches are arising from the spent fuel containment pool at Fukushima Daiichi’s reactor unit No. 4.

TEPCO said the water level in the pool storing the spent fuel rods at the Fukushima Daiichi's nuclear plant's No. 4 reactor may have dropped, exposing the rods.

The firm said it has not yet confirmed the current water level or water temperature in the pool and will try to pour water into the facility from Wednesday through holes that were created following an explosion earlier Tuesday in the walls of the building that houses the reactor.

Unless the spent fuel rods are cooled down, they could be damaged and emit radioactive substances. The government's Nuclear and Industrial Safety Agency urged TEPCO to inject water into the pool soon to prevent heating of the fuel rods.

“This is very serious because the fuel is outside of any kind of containment,” said Bellona’s Bøhmer. “This will lead to excessive radiation and have a severe environmental consequences and put further radiation out into the atmosphere.”

Bøhmer pointed out that the boiling spent fuel ponds ratchet up the danger to humans.

“Particularly, this increases radiation to which people could be subjected,” he said. The burning radioactive elements would release caesium, strontium, uranim and perhaps plutonium

@Alblee Meanwhile TEPCO also said water in a pool storing spent nuclear fuel rods may be boiling, an ominous sign for the release of high-level radioactive materials from the fuel, which was confirmed by the International Atomic Energy Agency (IAEA), with reference to reports from Japanese authorities.(not sure which pool??)

Hydrogen leaking from the pond caused yet another explosion this morning at reactor unit No. 4, TEPCO said, according to the Epoch Times, which led to a fire.

Looks like #1 is in bad shape too: As a result, the temperature at the top of the reactor was 107.3 degrees Celsius Thursday morning, down 24.7 degrees from before the water increase. The temperature at the bottom of the reactor had dropped 12 degrees to 98.5 degrees Celsius. www3.nhk.or.jp

Now they say water is not leaking from #4 "Tokyo Electric Power Company now says it is unlikely that water is leaking from the spent fuel rod pool of the Fukushima Daiichi power plant's No.4 reactor. www3.nhk.or.jp

@ch thanks for that Radiation Comparison chart, that is a good timeline. But I read only one explosion for #4 unit, at 6.00. The explosion at 6.14 would be #2.

there is confliciting data about this #4 reactor out there, and it is good to have that on record. For instance, this is from Wikipedia. Just the one fire is mentioned.

Thanks and respect @all for keeping up this labour of truth finding.

Did we see this either Wednesday or Tuesday? (Sorry if redundant)

Radioactive Strontium Found in Hilo, Hawaii Milk
Jeff McMahon April 27, 2011 blog in Forbes.Com: THE INGENUITY OF THE COMMONS

"A radioactive isotope of strontium has been detected in American milk for the first time since Japan’s nuclear disaster—in a sample from Hilo, Hawaii—the Environmental Protection Agency revealed yesterday..."

And here, below is the EPA April 26 PDF:

Good morning @elainekirk.
Sorry, have to step off this desk for about three hours ... Be back later, thanks.
@alblee Have a good day . I will draw the strontium to the attention of others .

In Minamisoma, spring has arrived. Birds chirp from the roof of a traditional house in Kobama ward by a hill where a cherry tree is in full bloom.

Police officers in protective suits walk along a cracked road as they search for bodies at a destroyed area about 18 kilometers from the damaged Fukushima nuclear plant in Minamisoma, Fukushima Prefecture April 10.

But the picture-postcard setting is just 19 kilometers from the crippled Fukushima Daiichi nuclear plant, and 500 meters from the shoreline. It’s completely abandoned.

When Minamisoma resident Shun Ishikawa turns around from viewing the house, he sees the plain of devastation brought by the March 11 tsunami. The levee that once protected the coastal town is destroyed, and the bridge over the Ohta river that leads to the sea is in ruin. Bare foundations of houses and soaked futons are the remnants that show people once lived there.

@Nancy : the question is, how do they think to prevent them from monitoring ?

@Nancy : they won't try to do that.

Something weird. There is a post on physicsforums that is talking about a unit 4 sfp theory. It links to an article that I can't get to coming down through the English version of the online news. Plus the date in the link is 20110316. Looks very weird to me. Post 5268. www.physicsforums.com

@Scilla That is odd. I wonder where they got that info and if it is accurate. Part of the work being done was the shroud replacement that requires the reactor to be drained. There were also mentions of reactor parts being in the SFP. I don't know why the reactor would still be full of water at that point. Translation of the article: When the explosion caused a fire that occurred March 15 in the No. 4 nuclear power plant Fukushima Daiichi TEPCO, the storage pool at a spent nuclear fuel flows into accidental water from the adjacent area by the impact of the explosion there in the pool could be overheating 食I止Meta or nuclear fuel, TEPCO's survey found.

If the melting continues heating fuel, has also got the worst radioactive material is released substantially more than the status quo.

The nuclear power plant, east of the earthquake tsunami attacked on March 11, an external power supply disruptions. ４号機の燃料 Also stopped to fuel pool cooling water injection in Unit 4. 東電は現 TEPCO is now suspect that about 70 tons of water evaporates from the pool one day, but ready-mixed concrete pumping machine for injection, water level rise is not as calculated. 東電はInvestigated as a suspect but there TEPCO is leaking water from the pool to the lower leakage of the reactor building has not been confirmed.

爆発は原子炉建屋の側壁が崩落するほど激しく、水素爆発が起きたとみられる。 The more intense the explosion collapsed walls of the reactor building, believed to be hydrogen explosion. 水の漏出先として東電が有力視しているのは、可動式のゲートを挟んでプールに隣接する「原子炉ウェル」。 TEPCO has been a strong candidate for a water leak which is adjacent to the pool of movable gates across the well "reactor. The explosion damaged the gate, it is likely that water is leaking into the reactor well.

aaaaand now we are back to admitting the SFP in 4 is leaking newsonjapan.com

Reporter I am in contact w/ is working on a followup article to the initial article where officials are blaming the iodine 131 in Philadelphia drinking water on patient excretion. Several things don't add up there as far as I'm concerned. Levels have been in the range of 3-4 picocuries 4 different times in the last 3 years or so. Recently levels are 2.2 piC/L, and they made the statement that "last Aug levels were nearly twice as high" for 131 in drinking water. What they didn't mention is that levels exceeded 3 pi/C in January 09 and also in Oct 07. That info has not made the press yet. RAINwater at Limerick (an hour outside of Philly) has had some of the highest levels of iodine 131 in the nation at 100 pCi/L, as well as the rainwater at TMI. Reporter is currently writing a follow up and I've been contacting other press about covering this issue. Should I take it to the unmod board, since it isn't directly related to Japan, or address it here since the reports are "technical" in nature and may relate to releases in other parts of the country?
