PARIS (AFP) - A pool containing spent fuel rods at Fukushima's No. 4 reactor "is the major concern" in Japan's nuclear crisis, presenting the risk of radioactivity being released directly into the air, a French safety agency said on Wednesday.
The deep tank at the reactor unit contains used fuel rods which are extremely radioactive and normally are kept immersed in cooling water.
Unlike the fuel rods that are used in the reactor vessel, the spent rods are not surrounded by a steel-and-concrete containment vessel, which is designed to confine leaks of radioactive gas and particles.
Instead, they are housed in the overall building covering the No. 4 unit, which has been "badly damaged," the Nuclear Safety Authority (ASN) said in a statement.
Fires broke out on Tuesday and again early Wednesday in the area of the fuel-rod pool before being extinguished, the agency said.
"The state of the fuel rods stored in this pool, which have been potentially affected by the fire, is not known," it said.
"The evaporation of water in the pool is continuing," the ASN said.
If the tanks run dry, the rods can overheat and the metal sheaths that surround the fuel can be ruptured, the ASN said.
"The Japanese authorities have consequently indicated there is the possibility of releases of radioactivity directly into the atmosphere."

^^ LOL I don't really beleive it.
I only wish people from Vancouver will act like the people in Japan now. Man even when you go slower in a line up the behind you is bitching at you ><
This is supposed to be a photo of the downed statue. I'm personally not too sure, as the cloud pattern in the upper left corner looks cloned, and something weird with the colours just above the severed legs.

The Godzilla taking a bath image is a little poor taste, but some of the images are beautiful, others have a strange misunderstanding of Asian culture...

Although the organization has told its member countries that the first indication of radiation would hit on Friday, the plume from a North Korean nuclear test in 2006 took about two weeks to travel to North America, U.N. officials said.

US: no water in spent fuel pool at Japan plant
Japanese government denies it
The Associated Press Mar 16, 2011 13:27:53 PM
WASHINGTON (NEWS1130) - The chief of the US Nuclear Regulatory Commission said Wednesday that all the water is gone from one of the spent fuel pools at Japan's most troubled nuclear plant, but Japanese officials denied it.
If NRC Chairman Gregory Jaczko is correct, this would mean there's nothing to stop the fuel rods from getting hotter and ultimately melting down. The outer shell of the rods could also ignite with enough force to propel the radioactive fuel inside over a wide area.
Jaczko did not say Wednesday how the information was obtained, but the NRC and US Department of Energy both have experts on site at the Fukushima Daiichi complex of six reactors. He said the spent fuel pool of the complex's Unit 4 reactor has lost water.
Jaczko said officials believe radiation levels are extremely high, and that could affect workers' ability to stop temperatures from escalating.
Japan's nuclear safety agency and Tokyo Electric Power Co., which operates the complex, deny water is gone from the pool. Utility spokesman Hajime Motojuku said the "condition is stable'' at Unit 4.
^^ part of the reason why the paramedic team from BC left Japan and came back, they said they werent equipped to work in a radioactive environment
also why the military wasnt able to air drop acid/water onto reactor 4 due to radiation etc
but this was all news from yesterday morning so things have likely changed
Status of quake-stricken reactors at Fukushima nuclear power plants
TOKYO, March 17, Kyodo
The following is the known status as of Thursday evening of each of the six reactors at the Fukushima No. 1 nuclear power plant and the four reactors at the Fukushima No. 2 plant, both in Fukushima Prefecture, which were crippled by Friday's magnitude 9.0 earthquake and the ensuing tsunami.
Fukushima No. 1 plant
-- Reactor No. 1 - Suspended after quake, cooling failure, partial melting of core, vapor vented, building damaged Saturday by hydrogen explosion, seawater being pumped in.
-- Reactor No. 2 - Suspended after quake, cooling failure, seawater being pumped in, fuel rods fully exposed temporarily, vapor vented, building housing reactor damaged Monday by blast at reactor No. 3, damage to containment vessel on Tuesday, potential meltdown feared.
-- Reactor No. 3 - Suspended after quake, cooling failure, partial melting of core feared, vapor vented, seawater being pumped in, building housing reactor damaged Monday by hydrogen explosion, high-level radiation measured nearby on Tuesday, plume of smoke observed Wednesday and presumed to have come from spent-fuel storage pool, severe damage to containment vessel unlikely, seawater dumped over pool by helicopter on Thursday, spraying water at it begun from ground.
-- Reactor No. 4 - Under maintenance when quake struck, fire Tuesday possibly caused by hydrogen explosion at pool holding spent fuel rods, abnormal temperature rise in spent-fuel storage pool, fire observed Wednesday at building housing reactor, pool water level feared receding, renewed nuclear chain reaction feared.
-- Reactors Nos. 5, 6 - Under maintenance when quake struck, temperatures slightly rising in spent-fuel storage pools.
-- Spent-fuel storage pools at all reactors -- Cooling functions lost, water temperature or level unobservable at reactors No. 1 to 4.
Fukushima No. 2 plant
-- Reactors No. 1, No. 2, No. 4 - Suspended after quake, cooling failure, then cold shutdown.
-- Reactor No. 3 - Suspended after quake, cold shutdown.
Although the organization has told its member countries that the first indication of radiation would hit on Friday, the plume from a North Korean nuclear test in 2006 took about two weeks to travel to North America, U.N. officials said.
seems to me that guy is just doing it for the cash right now. You go to his camera and adds pop up right away. I'm sure he's getting paid large money for that. With 2000 viewers right now I'm sure he's laughing all the way to the bank.
i would love to see more rebuild pictures with a kind of b4 and after like what it looked like when tsunami/earthquake hit to what it look like after rebuilding
^Probably pretty fast with today's technology, experience and wealth. Not sure but I believe it took them about 10 years to rebuild Hiroshima--69% of the city was flatten by the nuke from Americans on August 1945 and then it was hit hit again with a typhoon a month later.
Thierry Charles, a safety official at France's Institute for Radiological Protection and Nuclear Safety, [IRSN] said: "The next 48 hours will be decisive. I am pessimistic, because since Sunday I have seen that almost none of the solutions has worked." He described the situation as "a major risk", but added: "All is not lost, and I hope that the Japanese can find a way."
Asked about the maximum possible amount of radioactive release, he said "it would be in the same range as Chernobyl".
Francois Baroin, a French government spokesman, went further, saying: "In the worst of cases, it could have an impact worse than Chernobyl." He added: "Let's not beat about the bush. They have visibly lost the essential of control. That is our analysis, in any case, it's not what they are saying." http://www.vancouversun.com/news/Jap...464/story.html
In situations like this you have to look at what the worst case scenario could be, its an instinct that smart people have used to survive through out human existence.
I dont know about everyone else, but I have more confidence in a French radiological protection and nuclear safety official then the all knowing forum members here that release wads into tissue paper in their spare time.

Arash I just wanted to say goodbye. It was fun having you around but in actual fact... No one is going to miss you on RS. Be sure to make a new account down the road some time when you have your kits final production done and show RS your accomplishments.
