  • Here is more evaluation on ppIV-78: "After the earthquake, water injection continued through the reactor core isolation cooling system (RCIC). Around 12:00 on May 12, the RCIC stopped operation. Alternatively, water injection was made through the high-pressure coolant injection system (HPCI) but the reactor pressure decreased and thus the reactor water level is estimated to have increased. Before dawn on the morning of March 13, however, the reactor pressure dropped and HPCI stopped operation.
    The stoppage of HPCI is estimated to have triggered the reactor pressure to exceed the operation pressure of about 7 MPa. But the main steam safety relief valve (SRV) is estimated to have been activated to release the vapor to S/C to maintain the pressure at around the 7 MPa level, during which time it is estimated that the reactor water dropped and the reactor fuel was damaged.
    It is estimated that the main steam SRV opened to lower the reactor pressure, and at 9:25 on March 13 alternative injection was carried out and wet vent operation done in response to the increase in PCV pressure. It was reported that the alternative injection from fire engines was executed, but this measure could not demonstrate the required performance due to the relation with the reactor pressure, etc. as the water level has not been restored yet. More detailed investigations and analyses of the conditions/situations of equipment would be necessary in order to find out to what extent such measures worked."
    No reasons given why the pumps stopped.

  • The assessment concludes on pIV-79:"Regarding the progress of events in the accident at Unit 3, previous analyses showed that the RCIC and HPCI ceased to function, so PCV spraying using fire engines and wet vent operation were carried out. In addition, there is the possibility that, based on the water level situation following the start of fresh water injection and RPV pressure reduction operations, not enough water was injected and it is estimated that the lack of sufficient cooling led to core melt, with the melted fuel moving down to the bottom of the RPV.
    From the balance between the injected water volume and volume of steam produced, it is estimated that the water injected into the RPV is leaking.
    Based on the RPV temperature measurement results, it is considered that a considerable amount of fuel is cooling on the RPV bottom."

    Description
    Japanese lumber and household goods have begun appearing on the British Columbia coast in what many locals think is the vanguard of a wave of debris from last March’s Japanese tsunami that will eventually clog West Coast beaches with cars, boats and even waterlogged houses. “I found more debris in 10 minutes than I have in four years … and it’s all Japanese in origin,” said Perry Schmunk, Mayor of Tofino, a community of 1,600 on the west coast of Vancouver Island. In addition to Japanese drink bottles, Mr. Schmunk said he has found toothbrushes and a child’s sock. Known in Japan as the T?hoku earthquake and tsunami, the March 11 disaster killed upwards of 20,000 people and swept away an estimated 200,000 buildings. This fall, researchers at the University of Hawaii claimed that 20 million tonnes of debris had been washed to sea by the tsunami, and that, according to their models, it would not hit North America until 2013. In late September, a Russian ship reported sailing through a field of tsunami debris near the Midway Islands — about 5,000 kilometres west of the B.C. coast. Crew members described seeing furniture, appliances and a 20-foot fishing boat from Fukushima, the area hardest hit by the tsunami. hisz.rsoe.hu

  • TEPCO Press Release (Dec 22,2011)
    Plant Status of Fukushima Daiichi Nuclear Power Station (as of 3:30 pm, December 22). ---UNIT 1 (Shut down) On December 22, according to the operational record thus far, we changed
    the volume of nitrogen into PCV and that of gas emitted from PCV gas
    control system. At 10:35 am on the same day, we decreased the nitrogen
    injection amount from approx. 18Nm3/h to approx. 13Nm3/h. In addition, at
    11:45 am, we confirmed the volume of gas emitted from the gas management
    system decreased from approx. 30Nm3/h to 26.9Nm3/h. ---UNIT 2 (Shut down) On December 22, we conducted the sampling of the gas management system.
    According to our radionuclide analysis, Xe-135 at the entrance of gas
    management system was below detection limit (1.1x10-1Bq/cm3), and we
    confirmed that is below the determination criteria for recriticality such
    as 1Bq/cm3.
    ---UNIT 3 (Shut down) (From 1:30 pm to 3:15 pm on December 22, we injected hydrazine (corrosion inhibitor)) At 9:43 am on December 22, At the Alternative Cooling apparatus of Spent
    Fuel Pool Cooling and Filtering System, since the suction force of
    primary circulating pump decreased, we stopped the pump to conduct flushing of entrance-side strainer of primary circulating pump and
    stopped cooling of spent fuel pool. (The temperature of pool is approx.
    13°C when the pump stopped)
    Then, we flushed the strainer so that the suction force recovered. Thus,
    at 11:06 am on the same day, restarted the pump and began to cool the
    spent fuel pool. (The temperature of pool is approx. 13°C when the pump restarted)
    ---UNIT 4 (Shut down) (No update reported)
    by MaryW 12/22/2011 6:28:34 PM

  • (Continued) UNIT 5 (Shut down) At 10:11 am on December 22, since we finished the recovery work of
    seawater pump (System B) of equipment water cooling system, we made a
    trial run. At 11:25 am on the same day, we confirmed no abnormalities and
    restarted the operation. UNIT 6 (No update reported) OTHER-- At 10:00 am on December 22, we started to replace the transmission parts
    of monitoring post No.2 and No.8 which monitor dose rate inside the site.
    At 11:40 on the same date, we finished the replacement work. In addition,
    monitoring post No.8 data was unavailable from 11:10 am to 11:40 am, but
    we confirmed that the other monitoring posts didn't indicate unusual
    values. Monitoring post No.2 was available during the replacement work
    due to the replacement parts are different from Monitoring post No.8.

  • Fukushima N-Reactor Cooling System Stopped Manually Before Explosion
    Tokyo, Dec. 22 (Jiji Press)--A cooling system for the No. 3 reactor of the crippled nuclear power plant of Tokyo Electric Power Co. <9501> was switched off manually, leading to the reactor's explosion three days after the plant was hit by the 9.0-magnitude earthquake and ensuing tsunami on March 11, TEPCO said Thursday.
    A worker at the Fukushima No. 1 plant voluntarily stopped the high-pressure coolant injection (HPCI) system, one of emergency cooling apparatuses for the reactor's core, for fear of damage on the system and resulting radiation leaks, TEPCO said.
    Instead, the worker tried to cool the core by injecting water using a diesel-powered pump.
    But because a valve to release the air pressure inside the reactor failed to work as its battery was dead, water did not enter, and the hydrogen explosion occurred shortly past 11 a.m. on March 14 JST, the company explained.
    Previously, TEPCO told that the HPCI system stopped working because its battery ran out.

  • Some questions about the contaminated rice problem.

    1. What happens when the known bad rice? Is it destroyed (where/how)? Is it mixed with enough clean rice so it "passes" the Bq/Kg test so it can be sold? Export it to 3rd world countries that do not check for radiation?

    2. In Japan how do they handle the "rice straw". Burn it? Feed it to cattle? Plow it under in the fields? Does the Fuku province do anything special with rice straw from fields with contaminated rice?

  • Panel sees gov't evacuation order in nuclear crisis as irrational

    TOKYO, Dec. 23, Kyodo

    A government panel investigating the nuclear crisis at the Fukushima Daiichi power plant is expected to point out in its upcoming report that the government's evacuation order issued shortly after the accident was irrational, sources close to the matter said Thursday.

    The order instructed people living within 20 kilometers of the plant to evacuate. Panel members believe the order led some residents to move to areas where radiation levels were higher and caused confusion, the sources said.

    The government's nuclear safety agency and the science ministry had data that would have helped prevent people from unnecessary radiation exposure, but they did not report it to the crisis management center at the prime minister's office, thinking that the data was ''merely a hypothetical calculation result,'' according to the sources. english.kyodonews.jp

    Japan plans to relax its ban on exporting weapons to enable participation with other countries in the joint development and production of arms, and provision of equipment for humanitarian purposes, government sources said Thursday.

    It is the first time to make drastic changes to the country's long-standing arms export ban, although there have been some exceptions in the past.

    The sources said the government is making final arrangements for Chief Cabinet Secretary Osamu Fujimura to release a statement next Tuesday on reviewing the ban to be in step with the current global environment regarding weapons. english.kyodonews.jp
