  • Fukushima plant crisis could erupt if water injection stops for 38 hrs

    The reactors would then start emitting massive amounts of radioactive substances, raising the radiation level around the plant's premises above 10 millisieverts, the benchmark for prompting an order to evacuate.

    webmasters comment:

    Ok, so what we learned is that when 10mSv starts poping up all over the place, not just pipes and cracks, it's hands up and good luck? Forever.

    Or why is it that we are being fed this article a few days after reported underground tremmors?

  • Anti-nuclear rallies staged across US

    Anti-nuclear rallies have been staged across the United States amid growing concerns about the safety of the nation's more than 100 nuclear reactors.

    Demonstrations held on Saturday at 15 locations in the US were inspired by the accident at Japan's Fukushima Daiichi nuclear power plant in March.

    Americans are increasingly concerned about the safety of 104 nuclear reactors in the country. A recent tornado and an earthquake shut down over a dozen reactors on the east coast.

  • Debris incinerators up and running in Sendai

    The city cleared away about 73 percent of roughly 1.35 million tons of debris by September 22nd. The debris has been stored at 3 facilities.

    The facilities have temporary incinerators, the first of the kind introduced in Miyagi Prefecture. Two of them began operations on Sunday.

  • Kucinich joins protesters at Toledo anti-nuke rally
    We have to take a direction in Washington that is committed to [alternative energy] sustainability,

    said Mr. Kucinich, the representative from Cleveland who has been a longtime critic of nuclear power.

  • Wave power excites as next energy source

    Researchers have estimated that ocean waves could produce around the same amount of electricity for Japan as 36 nuclear reactors, but the development costs would be high and there are still many technological challenges before putting waves into practical use alongside solar power.

  • Amazing Medical, Physics and Engineering Breakthroughs

    Physics and Engineering Breakthroughs

    CERN announced that they had measured particles – neutrinos – traveling faster than the speed of light. If true, this would turn our basic physics understanding on its head.

    Many noted that the brilliant scientist Nikola Tesla predicted faster- than-light “neutrons” in 1932:

    All of my investigations seem to point to the conclusion that they are small particles, each carrying so small a charge that we are justified in calling them neutrons. They move with great velocity, exceeding that of light.

  • Anti-Nuclear Tent at METI Building

    Activists have been "camping" in front of the Ministry of Economy, Trade and Industry (METI) building since Sept, 11, to protest the Japanese government’s decision to restart existing nuclear power plants and carry on with construction of unfinished plants.

    They argue that the accident at the Fukushima Daiichi nuclear power plant has shown the grave human and ecological cost of nuclear energy and citizens now require the truth about its long-term impacts, not pro-industry reassurances.

  • Ministry maps strontium, plutonium fallout

    Levels of strontium in soil near the Fukushima No. 1 nuclear power plant are up to six times the highest concentrations deposited in Japan by pre-1980 atmospheric nuclear tests, according to the science ministry.

    Official maps of soil contamination by strontium and plutonium were published for the first time on Sept. 30 and reveal that, while concentrations are dwarfed by the radioactive cesium leaked from the stricken plant since March 11, significant quantities are present in some locations.

  • TEPCO Now Says There Was No Hydrogen Explosion at Reactor 2

    The committee reversed the company's position that there had been a hydrogen explosion in Reactor 2, and now concluded there was no such explosion. As to the tsunami that triggered the accident, the committee says "it was beyond expectations"; of the delay in initial response to the accident, the committee concludes "it couldn't be helped". Overall, the report looks full of self-justification. TEPCO plans to run the report with the verification committee made of outside experts before it publishes the report.

  • Report finds 7 cases of events staged in Japan to promote nuclear power

    TOKYO -- A panel has confirmed seven instances of the government of Japan arranging to have people attending symposiums on nuclear energy ask questions that favor nuclear power generation.

    In its final report released Friday, a third-party committee set up to investigate such questions said it had newly discovered four more cases, bringing the total to seven.

  • Radioactive water found beneath Georgia nuclear Plant Hatch

    The Atlanta-based Southern Co. learned of the leak beneath Plant Hatch in Baxley on Wednesday when it identified radioactive tritium in two test wells about 25 feet below the ground, said Dennis Madison, a utility vice president who oversees the plant.

    Workers guided by ground-penetrating radar were planning to dig Friday to identify the source of the leak.

    Exposure to tritium increases the risk of developing cancer.

  • Nuclear power plants and earthquakes

    Japanese, and most other, nuclear plants are designed to withstand earthquakes, and in the event of major earth movement, to shut down safely.

    In 1995, the closest nuclear power plants, some 110 km north of Kobe, were unaffected by the severe Kobe-Osaka earthquake, but in 2004, 2005, 2007, 2009 and 2011 Japanese reactors shut down automatically due to ground acceleration exceeding their trip settings.

    In 1999, three nuclear reactors shut down automatically during the devastating Taiwan earthquake, and were restarted two days later.

    In March 2011 eleven operating nuclear power plants shut down automatically during the major earthquake. Three of these subsequently caused an INES Level 7 Accident due to loss of power leading to loss of cooling and subsequent radioactive releases.

  • TEPCO finds own nuclear accident manual useless

    TOKYO (Kyodo) -- Tokyo Electric Power Co.'s in-house report showed Sunday the utility has found its own emergency manual was useless for handling the crisis at the Fukushima No. 1 Nuclear Power Plant

  • UPDATE 2-Tohoku Electric aims to triple wind power by 2020

    TOKYO, Sept 30 (Reuters) - Tohoku Electric Power Co said on Friday it aims to accept more than triple the capacity of wind power to its grid at 2 gigawatts by 2020 to meet needs to build wind farms in the region whose wind potential is among the highest in Japan.
