Kyodo, Feb 23, 2017: Smoke emerges at TEPCO’s Niigata nuclear plant — Smoke emerged at a service building of the Kashiwazaki-Kariwa nuclear power plant in Niigata Prefecture on Thursday but it quickly halted after a firefighting effort by workers, its operator said. Tokyo Electric Power Company Holdings Inc. said there was no radiation leak in the incident. The utility has not identified the cause of the incident. The plant operator confirmed smoke coming out around 3:25 p.m. from a locker room inside the service building, located near the No. 6 and No. 7 reactors at the plant…

Xinhua, Feb 23, 2017: TEPCO unaware of cause of smoke at Niigata nuclear plant in latest blunder  — Tokyo Electric Power Company Holdings Inc. (TEPCO) on Thursday said that it had detected smoke billowing from a service room near two reactors at its Kashiwazaki-Kariwa nuclear power plant in Niigata Prefecture, located on the west coast of Honshu island. TEPCO said that there was no radiation leak as a result of the possible fire which occurred close to its Sea of Japan-facing reactors, although the utility has yet to comment on the cause of the fire. The plant operator said that it noticed smoke billowing out of a locker room inside the service building near its No. 6 and No. 7 reactors at the facility…

    Anyhow… I made another effort at pinpointing a spewing source; didn't get far, but the data lovers can stare at this for a few hours…

    • MVB you are familiar with the "speedi" that Japan has/had. Run it in reverse to find the point source.

      I know, not saying we can do this, but "they" could definitely do this.

      So they don't want to.

      • MVB MVB

        @ stock – " "speedi" […] Run it in reverse to find the point source."

        link? (many Japanese data links have gone bad and the existing ones have pathetic controls. What are the best Japanese radiation data sites?

        If you mean including Japanese data in my investigations, with data from places like http://new.atmc.jp/ yeah, I could… Might get back to it in March. It's not like this mess is going away this century, so… Got to get a couple things done that I postponed for my data crunching. After those are all done, I will most likely revisit.

      Thanks MVB, a lot of effort in your work.

      The RADNET spiking in the Dec.23 +/- timeframe is interesting.
      We had a good snow in Boise.

      Excellent sleuthing once again by MVB. Thanks MVB; your hard work is appreciated.


    2002 shut down – The reactors at the KK plant were shut down one by one after the discovery of deliberate falsification of data.

    1998 shut down – In January 1998, unit 1 was shut down after increasing radiation levels in the steam driving the turbine triggered alarms. The levels were reportedly 270 times the expected operating level.

    1997 -..smoke had been found coming from plant machinery

    1991 shutdown – unit 2 was automatically shut down following a sudden drop in oil pressure inside the steam turbine

    All reactors continue to use low-enriched uranium as the nuclear fuel; however, there have been plans drafted by TEPCO to use MOX fuel in some of the reactors by the permission of the Japanese Atomic Energy Commission (JAEC). A public referendum in the Kariwa village in 2001 voted 53% against use of the new fuel.

    After the 2002 TEPCO data fabrication scandals, the president at the time, Nobuya Minami, announced that plans to use the MOX fuel at the KK plant would be suspended indefinitely.

    It was the largest nuclear generating station in the world by net electrical power rating.


    In 2007, a 6.8-magnitude tremor caused a fire and radiation leaks that shut down TEPCO’s seven-reactor Kashiwazaki-Kariwa nuclear plant, the world’s biggest. The company later admitted that the plant had not been built to withstand such shocks.

    Or maybe not build 7 reactors near something called "Burning Mountain"?

      It's obvious to me that they do not care if these plants spew their contents into the environment. How many documented and "undocumented" cases have their been of the nuclear industry/military industrial complex "same thing" testing on innocent people. Here, there, everywhere.

      Here everyone, do sit out in this pasture and have a picnic with the misses. Don't mind that Radio iodine cloud we purposefully poisoned you with.

      Here, drink this radioactive milk, it's good for your babies.

      Now we fast forward to today and they say it's like eating potato chips. They know otherwise by killing and maiming but that's not the point.

      They simply do not care, they are insane with power. They hold in their hands the key to the destruction of everything.

      Weapon systems mean everything to those in charge. They are the ultimate power, money is nothing. It's just numbers in a computer.

      Do you guys get 'inversions'? That would be tragic.

      Utah is infamous for inversions..making the pollution deadly. Looks like UT will be the first to wear air filter masks.

    Hitachi Ltd., Mitsubishi Heavy Industries Ltd. and Toshiba Corp. have decided to delay the integration of their nuclear fuel businesses that was planned for spring due to reasons such as manufacturing hub-related problems and prolongation of a Japan Fair Trade Commission review.

    Specifically, the three Hitachi, Mitsubishi and Toshiba affiliates that are involved in these integration talks are as follows: Global Nuclear Fuel-Japan Co., Mitsubishi Nuclear Fuel Co., and Nuclear Fuel Industries Ltd. — of which U.S. company Westinghouse Electric Company LLC is a major shareholder.

    Democratic Party faces rift over advancing target to rid Japan of nuclear power…
    …But Renho has been in contact with various labor unions to win their understanding of the 2030 target. She told a news conference on Feb. 16 that she still hopes to declare an end to Japan's nuclear power in 2030 at the party convention on March 12, a day after the sixth anniversary of the 2011 Great East Japan Earthquake, tsunami and subsequent Fukushima nuclear disaster.

    …The footage shows that the deposited substances are scattered around in a wide area of the structure. TEPCO had planned to introduce a robot equipped with a camera into the reactor building possibly by the end of this month to fully probe the condition inside, but the footage has forced the utility to reconsider the plan.

    If the situation is left as it is, the time required to decommission and dismantle the power station, which is believed to take 30 to 40 years, could be prolonged and the estimated costs of decommissioning the plant, which has already been revised upward from the initial 2 trillion yen to 8 trillion yen, could further rise. TEPCO is required to foot the costs of decommissioning the Fukushima plant, but the expenses will be passed on to consumers who pay electric power charges.

    Feature: Almost six years on, Fukushima nuclear disaster still an ongoing nightmare


    …Invited by Tokyo Electric Power Company Holdings Inc. (TEPCO), Hua, along with some other foreign journalists, paid a visit to the crippled Fukushima Daiichi nuclear power plant.

    As the car he took approached the power plant, the radiation level rose quickly. Being 24 km away from the nuclear plant, the reading was about 0.114 microsieverts per hour, twice the amount of Tokyo, whereas being 15 km from the plant, the reading was 20 times higher.

    Inside the power plant and close to one of the crippled reactors, the machine showed that the radiation level there was as high as 150 microsieverts per hour.

    Dozens of workers wearing protection suits were spotted working by the No. 2 reactor, and according to a guide from TEPCO, the radiation level there was as high as 1,000 microsieverts per hour. Currently, some 6,000 staff are working in the Daiichi nuclear power plant.

      I see they are still saying it was all hydrogen explosions. Perhaps some were yes but I have no doubt in my mind that Unit 3 and it's load of plutonium mox fuel was not a hydrogen explosion.

      That thing was massive, high velocity and very dirty dark brown/black in color. Unit 3 was also shredded as well so yeah…. hydrogen explosion my ass.

  • HillbillyHoundDog HillbillyHoundDog


    …Most recently, on Feb. 15, Japan's nuclear watchdog blasted the utility for providing an extensive amount of inaccurate information related to plans to restart the two reactors in Niigata.

    TEPCO admitted that it had submitted information from three years ago that contained inaccurate information about buildings at TEPCO's Kashiwazaki-Kariwa plant in Niigata.

    The buildings were to be used as headquarters in case of an emergency.

    Japan's Nuclear Regulation Authority (NRA) heard from TEPCO officials that one of the buildings failed to meet the regulator's earthquake resistance standards in all 7 tests required to be passed by the NRA.

    The embattled utility said that the building had failed only 5 out of 7 of the NRA's tests and as a result told the regulator that was in the final stages of screening the No. 6 and 7 reactors that the building would not be used.

    TEPCO said its gaffe at that time was due to a communication problem between departments, to which the NRA slammed the error as being unacceptable and demanded further details and for TEPCO to resolve its blunder.

    The Japanese government has said it will likely continue its effective state ownership of TEPCO because the expected costs for decommissioning the Daiichi plant and paying compensation to the victims continue to escalate, with preventable oversights doing little to keep costs down or the timeframe…

    Get in there and re-tweet!

    If you don't have Twitter, open one up. It's easy and better than Fakebook, IMHO, as Fakebook seems to be censoring.

    By the way, for what reason is Fakebook allowed to ask you for your private I.D. ? There is no reason for them to have it and there is no reason for them to be allowed to ask for it. It's information-gathering. Just like Disney requires a FINGERPRINT to enter their theme parks. It's information-gathering.

    The whole story..

    First, please take a good look at this:

    Norwegien Radiation Protection Authority

    The Radiation Protection Authority currently operates five air filter stations that are part of the agency’s own air monitoring system. The stations are located in Stavanger, at the Authority’s head office at Østerås, near Oslo, at Skibotn, at Viksjøfjell and at the Radiation Authority’s preparedness unit at Svanhovd.

    The air filter stations are also equipped with a special impregnated charcoal filter that can capture the short-lived radioactive gas, iodine, that is the indicator of a new emission.

    2 pages, photo of detector [strange looking] other info..maps


    The air filter station at Svanhovd, **Russia’s Kola Peninsula, was the first to measure small amounts of the radioactive Iodine-131 in the second week of January.

    Enter..Russia's Kola Peninsula..site of 'the leak' [imo]

    The Kola Peninsula is a peninsula in the far northwest of Russia. Constituting the bulk of about 137 active and 140 decommissioned, 58 reactor units weighing 1600 tons EACH, idle naval nuclear reactors, produced by the Soviet military.

    http://www.exchangemonitor.com/publication/rwm/nrc-rejects-petition-on-post-fukushima-spent-fuel-monitoring/NRC Rejects Petition on Post-Fukushima Spent Fuel Monitoring

    The Nuclear Regulatory Commission has denied a petition from a retired Department of Energy physicist calling for the agency to mandate increased monitoring of nuclear plants’ spent nuclear fuel pools and reactors to prevent a disaster similar to the 2011 Fukushima Daiichi triple-meltdown in Japan.

    …Petition No. “PRM-50-113 provided no sufficient basis to revise the regulations as requested; therefore, the NRC is denying PRM-50-113,” Vietti-Cook wrote.

    …DeVolpi, a nuclear physicist who worked at the Argonne National Laboratory in Illinois for 41 years to 1999, said he had developed instrumentation that could provide monitoring capabilities for crucial thermodynamic parameters. Such systems for reactor water-level monitoring could have prevented or slowed one to two of the reactor meltdowns at Fukushima Daiichi, according to his petition.
