TEPCO backs off cause of explosion at nuclear plant2011/06/07
Contrary to what it said last week, Tokyo Electric Power Co. (TEPCO) now believes that it is unlikely that the March 12 hydrogen explosion at the No. 1 reactor building of the Fukushima No. 1 nuclear power plant was caused by the reverse flow of hydrogen gas from the containment vessel into the reactor building.

The utility said that on June 4, it found records saying that one of two valves in an exhaust pipe was designed to shut down automatically when a power source was lost, and probably did close. That would have prevented the flow of hydrogen from the containment vessel into the reactor building.

TEPCO has yet to confirm whether the valve actually shut down automatically, company officials said.

When the Great East Japan Earthquake and subsequent tsunami hit the nuclear power plant on March 11, all power was cut off.

In the No. 1 reactor building, the exhaust pipes from the reactor building and the containment vessel were joined into a single pipe that then vented all exhaust gases from both to the outer atmosphere.

On March 12, authorities attempted to release hydrogen gas that had built up inside the containment vessel to prevent an explosion. The gas was supposed to be released to the outer atmosphere.

Earlier, TEPCO officials theorized that hydrogen gas from the containment vessel had instead flowed down the pipe into the reactor building through two open valves. As a result, hydrogen would have accumulated inside the reactor building, leading to the explosion.

On June 3, the utility reported that theory to the Nuclear and Industrial Safety Agency (NISA) of the Ministry of Economy, Trade and Industry (METI).

On June 4, however, TEPCO officials rechecked their records from last year's regular inspections. They discovered then that one of the two valves was designed to seal itself automatically when power was lost.

As it is contained in a simple automatic system, officials think it likely that the valve shut down properly.

TEPCO is continuing its investigation into the cause of the explosion.

Japan to send medical officer to U.N. nuclear watchdog

TOKYO (Kyodo) -- A medical officer of Japan's Ground Self-Defense Force will be sent to the International Atomic Energy Agency to instruct doctors on how to treat radiation victims and analyze information on radiation incidents, the GSDF said.

Lt. Col. Tetsuo Yamamoto, 41, will work at the Department of Nuclear Safety and Security at the Vienna-based agency for around two years from Wednesday as the first member of the Self-Defense Forces to be dispatched to the agency.

Yamamoto was involved in the health care of SDF personnel tasked with handling the disaster at the crippled Fukushima No. 1 Nuclear Power Plant. mdn.mainichi.jp

@Angie No worries :-)

Japan seeks enhanced cooperation in response to nuclear accidents

BUDAPEST (Kyodo) -- Foreign Minister Takeaki Matsumoto has called for enhanced international cooperation in responding to nuclear accidents and strengthening nuclear safety standards at a foreign ministerial session of the Asia-Europe Meeting in Hungary.

In a speech after the opening ceremony of the meeting, Matsumoto also expressed Japan's resolve to share data regarding the accident at the Fukushima nuclear power plant, triggered by the March earthquake and tsunami disaster, with the international community in a fully transparent manner.

Hi @all. Hope all are well.

@all Bye for now!

Sometime thye results precede the reports. www.slideshare.net

@Tenzing Thank you for the YT vid! Why does 'Fukushima' sound better when Mme Kosciusko-Morizet says the word? :)

When is the G20 meeting?

Fukushima aftermath: G20 to discuss nuclear safety "G20 energy ministers are set to meet in Paris to discuss nuclear safety in the wake Japan's Fukushima disaster." www.bbc.co.uk

G20, why don't they just call it the top 1 per center? That is who they work for.

Japan's nuclear crisis: Fukushima strategy creates 'bigger mess'
Water used to cool the plant forms pools of radioactivity.

"Under normal circumstances, Areva's system can decontaminate 50 tons of water per hour. But experts admit that it is hard to predict just how efficiently the system will handle water that contains not only radioactivity but also debris, oil and salt. Water might need to be treated numerous times before it can be dumped into the ocean.
"Normally the processing is done at small volumes, and you have carefully controlled chemistry," said Barrett, the nuclear engineer. "Here you have massive volumes and a very heterogeneous chemistry."
"Honestly, it's hard to say how it will work," said Patricia Marie, an Areva spokeswoman. "We hope everything will be fine."

Japanese Government Admits "Melt-Through" in Reactors 1, 2 and 3
www.yomiuri.co.jp
"...the Japanese government will now admit in the report to IAEA that the "melt-through" may have taken place in the Reactors 1, 2 and 3 at Fukushima I Nuke Plant.

According to Yomiuri, "melt-through" happens when the melted fuel leaked from the Reactor Pressure Vessel and deposits at the bottom of the Containment Vessel, and is considered worse than "melt down".
