This "ROV" (a Remote Operating Vehicle is a 'child diary' or liveblog coverage of major breaking news stories. The term was borrowed from the Gulf Watchers coverage of the Deep Water Horizon crisis)

This is another clearinghouse diary for discussion and commentary about the ongoing nuclear disaster(s) in Japan. Previous diaries are saved in the group page.

  • CNN reports that the two workers who were in #2 escaped without harm. A Japanese industry trade group suspects damage in the containment vessel as well as the core. However, they think the pressure in vessel is stable even though actual pressure and temperature readings are unknown.

    The level of contamination is about 1,000 times that of the leaked water already found in the basements of the Number 1 and 3 reactor turbine buildings.

    The company says the latest reading is 10-million times the usual radioactivity of water circulating within a normally operating reactor.
    TEPCO says the radioactive materials include 2.9-billion becquerels of iodine-134, 13-million becquerels of iodine-131, and 2.3-million becquerels each for cesium 134 and 137.

    These substances are emitted during nuclear fission inside a reactor core.

    The company says the extremely contaminated water may stem from a damaged reactor core, and are trying to determine how the leakage occurred.

    University of Tokyo graduate school professor Naoto Sekimura says the leak may come from the suppression chamber of the Number 2 reactor, which is known to be damaged. The chamber is designed to contain overflows of radioactive substances from the reactor.

  • Update BBC reports workers pulled from plant
    Leaking water at reactor 2 has been measured at 1,000 millisieverts/hour - 10 million times higher than when the plant is operating normally.

    Correction from AP approximately 3:18am EDT
    The millisevert measurement is for air rather than water. Presumably this is incorrect as well in the BBC story below.

    The air in Unit 2, meanwhile, measured 1,000 millisieverts per hour — four times the limit of 250 millisieverts deemed safe by the government, Tokyo Electric Power Co. spokesman Takashi Kurita told reporters.

    Workers trying to cool the reactor core to avoid a meltdown have been evacuated, Reuters news agency says.

    Earlier, Japan's nuclear agency that levels of radioactive iodine in the sea near the plant have risen to 1,850 times the usual level.

    The UN's nuclear agency has warned the crisis could go on for months.

    It is believed the radiation at Fukushima is coming from one of the reactors, but a specific leak has not been identified.

  • Update From NHK:
    Radioactive iodine in sea-water off Japan's crippled Fukushima Daiichi nuclear power plant rose to 1,850 times the usual level from 1,250 times measured on Saturday, Japan's nuclear safety agency said on Sunday.
    Separately, senior agency official Hidehiko Nishiyama said leakage from reactor vessels was likely to have been the cause for high levels of radiation found in water that has accumulated in turbine buildings.
    The article also states that
    TEPCO plans to drain the basement of the Number 2 reactor turbine building on Sunday, and is studying ways to drain the basement of the Number 3 turbine building.

    Radiation  levels soar in seawater near nuke plant

    Sendai, Japan • Radioactivity levels have soared in the seawater outside the troubled Fukushima Dai-ichi nuclear plant, safety officials reported Saturday, igniting fresh concerns about the spread of highly radioactive material and the risks involved in completing an already dangerous job.

    Samples taken 360 yards offshore from the plant Friday showed radioactive iodine levels 1,250 times the legal safety limit. Earlier in the week, the levels of iodine-131 in the water had been closer to 100 times the limit.

    And Japan’s government revealed a series of missteps by the operator of a radiation-leaking nuclear plant on Saturday, including sending workers in without protective footwear in its faltering efforts to control a monumental crisis.
    ::
    The world’s chief nuclear inspector said Saturday that Japan was “still far from the end of the accident” that has stricken its Fukushima nuclear complex and continues to spew radiation into the atmosphere and the sea. Yukiya Amano, the director general of the International Atomic Energy Agency, acknowledged that the authorities were still unsure whether the nuclear cores and spent fuel were covered with the water needed to cool them and end the crisis.

    He cautioned that the nuclear emergency could go on for weeks, if not months, given the enormous damage to the plants.

    In this case -- with the ocean contamination -- it is very bad for all of us. Ships that go in -- even in the Bay of Tokyo will likely become radioactive. The ocean in the area will become a decades-long environmental catatrophe -- affecting food availablity for Japan and Japanese food exports.

  • From SF Gate:
    Japan's government revealed a series of missteps by the operator of a radiation-leaking nuclear plant on Saturday, including sending workers in without protective footwear in its faltering efforts to control a monumental crisis...

    ...Government spokesman Yukio Edano urged Tokyo Electric Power Co. to be more transparent, two days after two workers at the tsunami-damaged Fukushima Dai-ichi plant suffered skin burns when they stepped in water that was 10,000 times more radioactive than levels normally found near the reactors.

    "We strongly urge TEPCO to provide information to the government more promptly," Edano said.

  • From NewScientist:
    Austrian researchers have used a worldwide network of radiation detectors – designed to spot clandestine nuclear bomb tests – to show that iodine-131 is being released at daily levels 73 per cent of those seen after the 1986 disaster. The daily amount of caesium-137 released from Fukushima Daiichi is around 60 per cent of the amount released from Chernobyl.

Rules of the Road

Please be kind to kossacks with bandwidth issues. Please do not post images or videos. Again, many thanks for this.

Both the Mothership and the ROVs are for reporting and discussing the developing news. Neither space is for opinions or editorializing on the subject of nuclear energy.

Remember when posting to the thread:  STICK TO THE FACTS. Source and link all new information.  (This includes insuring authenticity of twitter sources.)

CURRENT TIME IN JAPAN is just a click away for those who want to time/date stamp entries.

Please post news items to the ROV.

*ROV (Remote Operating Vehicle) is a term coined from the Gulf Watchers ongoing coverage of the Deep Water Horizon crisis in the Gulf of Mexico. It is used in place of the term 'child diary' and refers to a diary(s) running concurrently with the Mothership where ongoing discussion and updates to developing news stories occur.
* Please list any diary from the past two days which is not in above list in comments and we will pick it up for posting.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
