Japanese Simulation Studies Insufficient For Nuclear Radiation Risks: Greenpeace


  • Japanese Simulation Studies Insufficient For Nuclear Radiation Risks: Greenpeace

    AsianScientist (Dec. 2, 2011) – Greenpeace this week renewed its call for the Japanese government to keep its nuclear reactors offline as simulation maps of potential accidents at Japan’s nuclear plants have not been updated since the Fukushima disaster.

    Following a Greenpeace freedom of information request on November 25, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) released SPEEDI simulations of the radioactive contamination spread from all nuclear plants in Japan.

    The SPEEDI maps, which stands for “System for Prediction of Environment Emergency Dose Information,” were made to support emergency preparedness drills of local and central government authorities, calculate the concentration of radioactivity in the air, contamination on the ground, and dose to the population within a range of 10 kilometers. Based on these maps, drills on evacuation or sheltering of the population, or distribution of iodine pills are organized.

Meteorological Agency to announce more detailed information on tsunami


  • Meteorological Agency to announce more detailed information on tsunami

    Following the March 11 Great East Japan Earthquake, the agency observed tsunami waves in offshore areas before they actually hit the coastal areas, but was unable to make full use of the information to minimize damage.

    For example, a satellite observed about 6.5-meter-high tsunami waves around a GPS buoy some 20 kilometers off Kamaishi, Iwate Prefecture, about 10 minutes before the massive tsunami hit the coastal area of the city, according to the municipal government.

    The municipal government intended to warn local residents of the tsunami, but was unable to do so because of a power blackout.

Xenon 400,000 times normal found in Chiba air immediately after Fukushima nuke accident


  • Xenon 400,000 times normal found in Chiba air immediately after Fukushima nuke accident

    CHIBA -- Radioactive xenon-133 some 400,000 times normal levels was detected in the atmosphere here immediately after the outbreak of the crisis at the Fukushima No. 1 Nuclear Power Plant, a radiation survey organization said.

    It took three months before the volume of radioactive substances returned to normal levels. The Chiba-based Japan Chemical Analysis Center made the announcement during a radiation research session in Tokyo on Dec. 1, organized by the Education, Culture, Sports, Science and Technology Ministry.

Wholesaler handling Fukushima rice goes bankrupt


  • Wholesaler handling Fukushima rice goes bankrupt

    A Tokyo wholesaler that was handling rice from Fukushima Prefecture is set to become the nation's first rice wholesaler to go under due apparently to harmful rumors of radioactive contamination in connection with the crisis at the Fukushima No. 1 Nuclear Power Plant.

    Tokyo Shoko Research Ltd. said Dec. 1 that Watanabe Shoji K. K. based in Tokyo's Shibuya Ward was notified by the Tokyo District Court on Nov. 24 of the start of bankruptcy proceedings

Hunting registrations plunge in Fukushima amid nuclear crisis


  • Hunting registrations plunge in Fukushima amid nuclear crisis

    Hunting can be carried out in non-protected areas by registering with the prefectural government. The hunting season opened this year on Nov. 15. A prefectural hunting club survey found that about 400 club members, mainly from areas around the stricken nuclear plant, had evacuated to other areas, and the number of hunting club members, which stood at 3,542 last fiscal year, was expected to drop by about 1,000 this year.

    At the same time, meat taken from a wild boar and Asian black bear in the prefecture was contaminated with a radioactive cesium level of 14,600 becquerels per kilogram, some 30 times the government's provisional limit of 500 becquerels per kilogram.

Fukushima Earthquake Moved Seafloor Half a Football Field


  • Fukushima Earthquake Moved Seafloor Half a Football Field

    The March 2011 Tohoku-Oki earthquake that decimated Japan and its Fukushima nuclear reactors with a monster tsunami altered the seafloor off the country’s eastern coast much more than scientists had thought. Analysis released today in the journal Science indicates the ocean bed moved as much as 50 meters laterally and 16 meters vertically. The magnitude 9.0 quake occurred close to the nearby Japan Trench that runs north to south in the Pacific Ocean (dark blue line on the map below).

7 Nuclear Weapon Screw-Ups You Won't Believe We Survived


  • 7 Nuclear Weapon Screw-Ups You Won't Believe We Survived

    From the 1950s up through the early 1990s, the specter of nuclear war cast a shadow over the world like a giant, gloomy mushroom tattoo. Hollywood and our own morbid imaginations came up with any number of scenarios that would wipe out humanity in a series of blinding flashes: robots, Russian and American policies of mutually assured destruction. But Kubrick was probably closest when he imagined the nuclear era as a game of poker between cocky, absent-minded lunatics. Only he probably didn't go far enough. After all, he could have never imagined ...

Japan nuclear meltdown ?maybe worse than thought?


  • Japan nuclear meltdown ?maybe worse than thought?

    TOKYO — Molten nuclear fuel at Japan's Fukushima plant might have eaten two thirds of the way through a concrete containment base, its operator said, citing a new simulation of the extent of the March disaster.

    Tokyo Electric Power (TEPCO) said their latest calculations showed the fuel inside the No. 1 reactor at the tsunami-hit plant could have melted entirely, dropping through its inner casing and eroding a concrete base.

    In the worst-case scenario, the molten fuel could have reached as far as 65 centimetres (2 feet) through the concrete, leaving it only 37 centimetres short of the outer steel casing, the report, released Wednesday, said.

    Until now, TEPCO had said some fuel melted through the inner pressure vessel and dropped to the containment vessel, without saying how much and what it did to the concrete, citing a lack of data.

    "Almost no fuel remains at its original position," TEPCO said in the report.

Japan Govt Mulls Public Fund Injection into TEPCO


  • Japan Govt Mulls Public Fund Injection into TEPCO

    Tokyo, Dec. 8 (Jiji Press)--The government is considering injecting public funds into Tokyo Electric Power Co. in an effective move to nationalize the troubled power utility, in order to help the firm better cope with the ongoing nuclear crisis and ensure speedy compensation payments over the accident, it was learned Thursday.

    Through the recapitalization, the government aims to prevent TEPCO from falling into negative net worth, a situation that could stall the work to deal with the accident and nuclear compensation, informed sources said.
