  • Japan: New Smoke At Nuclear Plant
    Tokyo Electric Power Company (TEPCO), Nuclear and Industrial Safety Agency (NISA), and the Japanese government gave a joint press conference on Sunday and explained that an unusual amount of smoke that billowed from the Fukushima Daiichi nuclear power reactor on Saturday night was nothing to be concerned about.
  • Massive Fire Breaks Out At Fukushima Daiichi Nuclear Power Plant May 8th 2011
    A fire has broken out near the roof of Reactor 3

    Also some sort of object has been placed into the hole on the side of Reactor 4. It could be some sort of emergency draining equipment, or a spraying apparatus. More to follow

  • Accelerated Aging Effects of Radiation on Materials At Fukushima Daiichi
    There has been widespread criticism of TEPCO’s decision to dump radioactive materials into the Pacific Ocean, however little attention has been brought on the effects of radiation on materials at Fukushima Daiichi.

    Wet storage facilities are one of the most common technologies used for the management of irradiated fuel assemblies from power reactors.

    Some of the most controversial decisions made by plant operators involve the ageing of materials in ageing nuclear plants. Construction on Fukushima Daiichi began on July 25th, 1967, and it was first commissioned on March 26th, 1971.

  • Shut down being considered for Fukushima Power Station No. 2
    The govenrment is thinking of decommissioning the Fukushima No. 2 nuclear power plant in deference to those who have taken the brunt of the ongoing nuclear crisis, a government source said Saturday.

    Fukushima No. 2, which is situated on the Pacific coast about 10 km south of its crippled sister facility, Fukushima No. 1, successfully completed a cold shutdown after being hit by the March 11 quake and tsunami, which temporarily disabled its cooling systems.

  • Late expert gave forewarning of Fukushima nuke plant disaster draws attention on Net
    A short paper penned 16 years ago by an antinuclear scientist is drawing attention on the Internet for having warned about the dangers posed by the Fukushima No. 1 Nuclear Power Station and other old atomic plants.

    Jinzaburo Takagi, the late former director of the Citizens' Nuclear Information Center, also cautioned the government and utilities about their policy of not assessing the safety risks for nuclear power stations beyond their assumed scenarios.

  • Decision to suspend Hamaoka power plant delayed
    Chubu Electric Power Co. held an inconclusive board meeting Saturday over whether to suspend the Hamaoka nuclear power plant in Shizuoka Prefecture, as requested by Prime Minister Naoto Kan, participants said.

    The utility serving central Japan, including Nagoya, was to continue its discussions Sunday or later, they said.

  • U.S.-Japan joint survey reveals high radiation beyond evacuation zone
    The first map of ground surface contamination within 80 kilometers of the crippled Fukushima No. 1 nuclear power plant shows radiation levels higher in some municipalities than those in the mandatory relocation zone around the Chernobyl plant.
