  • The temblor cut off external power supply to the pumping machines for the three reactors at around 5:16 p.m. Tokyo Electric Power Co. revived the power supply and resumed water injections at 6:05 p.m., according to Nuclear and Industrial Safety Agency.

    If the water injection is stopped for hours, coolant water would be lost again... search.japantimes.co.jp

  • TEPCO president apologizes, one month later Shimizu apologized to people in and outside Fukushima Prefecture, saying his company has added to their physical and mental burdens with the nuclear crisis.

    He also said he regrets not meeting local residents first of all to offer an apology. He said he failed to do so because he was overwhelmed by handing the accident from Tokyo.
    He also said he was sorry that Fukushima Governor Yuhei Sato had refused his request to meet and receive an apology directly. www3.nhk.or.jp

  • @Sinthia Domina Prior to the 9.0 quake off the Japanese coast, 7.0 was the STATED maximum magnitude of an earthquake all nuclear plants were designed to withstand. A 7.0 quake was believed to be a rarity at the time the faclities were being designed and built. If you ask them now, the "experts" will tell you that the nuclear plants are designed to withstand earthquakes based on the average largest recorded quake in that locality...a good way to avoid answering with a direct response.

  • The 20-km evacuation zone around the crisis-hit Fukushima No. 1 nuclear power plant will soon be turned into a legally binding off-limits zone, senior officials said Sunday. The step is aimed at increasing government control over the area. Desperate residents have been braving radiation fears for quick return trips to pick up essential belongings. Officials suggested Sunday that they will now be able to force anyone out of the evacuation zone who refuses to leave. search.japantimes.co.jp

  • When asked what is most troubling to them now, 55 percent of respondents said they are frustrated with the lack of accurate information about the nuclear plant, and their future housing prospects. This was followed by 36 percent who said they have to stay at shelters without privacy and 11 percent who said they cannot move easily without their own cars or gasoline. www3.nhk.or.jp

  • Governor Shirakawa said the economy faces downward pressure on the production side due to damaged facilities, disrupted supply chains and power cuts.

    He also noted that some mainly mid- to small-sized companies are facing difficulty in raising funds despite emergency measures taken by the central bank. www3.nhk.or.jp

  • @Bobby1 Here's the remaining part of that quote from the article you posted that I found particularly disturbing: "Data for the west coast of the United States, which received the Fukushima radioactive fallout 6-10 days before France, reveals that levels of radioactive iodine-131 concentration are 8-10 times higher there, the institute says."

  • @borrrden could you please translate the "TITLE section" of the elevation drawing on #1 reator for me.....
    by fitter 4/11/2011 1:31:56 PM

  • @James Ward - They're still below the safety standards intentionally set low for long term considerations. This is, of course, subject to change along with the condition of the reactors.
    by Hank Scorpio 4/11/2011 1:37:21 PM

  • @James Ward Thanks, pregnant women & nursing infants on the west coast should either evacuate or take major steps to limit their exposure... Cesium is a problem there now too.

  • @fitter Where?
    by borrrden 4/11/2011 1:42:06 PM

  • @Hank Scorpio Went back and checked, I misread the way they expressed the cooling water injections as nitrogen, not enough coffee and the Nos. threw me. Need more coffee....
