    US_NPS Watta Bar 2 (TN) @ 100 % CONTAINMENT AIRLOCK FUNCTION LOST DUE TO EQUALIZING VALVE NOT CLOSING https://www.nrc.gov/reading-rm/doc-collections/event-status/event/2017/20170320en.html#en52618

    "On March 9, 2017 at 0120 EST, the equalizing valve for the Watts Bar Nuclear Plant (WBN) Unit 2 upper containment airlock inboard door was found not closed while the outboard airlock door was open.

    This created a containment bypass with leakage potentially greater than allowed by the design.

    The operator immediately identified, after opening the outer door of the elevation 757 Air Lock, the pressure equalizing valve for the inner door was not fully closed.

    The outer door was promptly shut to isolate the airlock. The inner door was then cycled which closed the equalizing valve.

    The total time that a containment bypass was present is estimated at five minutes.

    "This condition was initially recognized as being potentially reportable. However, the assessment performed at the time, based on operator control of the outer airlock door, concluded there was a reasonable assurance of meeting the safety function. A subsequent independent review of this condition identified that this should have been reported under 10 CFR 50.72(b)(3)(v)(C) within eight hours of the event.

    "The NRC Resident Inspector has been informed of this event."

    The licensee is planning on replacing the equalizing valve in the near future.

      [ the Event Date is Mar 17, Refueling Outage day 10 ]

      "At approximately 1517 [EDT], while restoring protective relay power to the 1B Reserve Auxiliary Transformer, a valid undervoltage actuation signal was sent to the 1B Emergency Diesel Generator (EDG).

      The 1B EDG automatically started and tied to the safety bus (1BA03).

      The 1BA03 bus was loaded by the automatic load sequencer.

      This actuation was identified by the Control Room Operators and the 1B EDG was locally monitored while in service.

      "This actuation is reportable due to the automatic actuation of a system listed in 10 CFR 50.72(b)(3)(iv)(B).

      "The reactor was not critical at the time of the event and not challenged throughout the event.

    Some trivia from the past. Remember Radioactive Boy Scout?

    Tried to build a breeder reactor in 1998. Sores all over his body.

    He died at 39 last November. Some controversy as to why he died at 39.

    Here is the belated explanation from his dad…

    Man who tried to build a homemade nuclear reactor didn’t die of radiation poisoning

    "I’m proud of my son and I’m very sad that he’s gone," says Radioactive Boy Scout's dad.

    On Tuesday, David’s father, Kenneth Hahn, called Ars to confirm that his son died of alcohol poisoning and that his previous nuclear experiments played no role in his passing. He said that he came upon our months-old request for comment while cleaning out old e-mails.

    Citing a toxicology and autopsy report, Kenneth Hahn said his son was found with a dangerous level of blood alcohol content, 0.404, late in the evening on September 26, 2016. The "radiation injury," he explained, refers to a small burn on David's wrist dating back to his experiments.

    "Dave was shopping at Walmart to get some food. It was around 10:30pm at night, and I guess he went to get some groceries," Kenneth Hahn said. "They found him in the restroom about 20 minutes later, deceased. There was no way to revive him."

    Kenneth Hahn added that he didn’t learn of his son’s death until the Shelby Charter Township police arrived at about 2am the following morning to inform him of the news.

    While looking for any video on the latest robot entry into Unit 1 with radioactive readings, found a selection of TEPCO videos. The link shows the current situation as of Jan '16 at Daiichi and you will be glad to know that the cafeteria feeds workers food grown in Fukushima.

    You will also see the contraption being built for Unit 3's spent fuel removal among other things like bolted tanks being swapped out for more secure ones and the site being mostly paved or concreted over to contain the fallout from the explosions.

    Soviet cover-up of nuclear fallout worse than Chernobyl
    More nuclear bomb tests were conducted at Semipalatinsk than anywhere else in the world during the 1950s and early 1960s. Western journalists have reported since the breakup of the Soviet Union on the apparent health effects on villagers downwind of the tests. And some recent studies have estimated radiation doses using proxies such as radioactivity in tooth enamel.

    Substantial contribution of extrinsic risk factors to cancer development

    Recent research has highlighted a strong correlation between tissue-specific cancer risk and the lifetime number of tissue-specific stem-cell divisions. Whether such correlation implies a high unavoidable intrinsic cancer risk has become a key public health debate with the dissemination of the ‘bad luck’ hypothesis. Here we provide evidence that intrinsic risk factors contribute only modestly (less than ~10–30% of lifetime risk) to cancer development. First, we demonstrate that the correlation between stem-cell division and cancer risk does not distinguish between the effects of intrinsic and extrinsic factors. We then show that intrinsic risk is better estimated by the lower bound risk controlling for total stem-cell divisions. Finally, we show that the rates of endogenous mutation accumulation by intrinsic processes are not sufficient to account for the observed cancer risks. Collectively, we conclude that cancer risk is heavily influenced by extrinsic factors. These results are important for strategizing cancer prevention, research and public health.

        A Friend Dies As Scientists Ponder: Just How Preventable Are Most Cancers?

        A dear friend died of lung cancer this week.

        She didn’t smoke and she had no other risk factors. A retired nurse and avid cook, she ate an exemplary diet, maintained a lithe figure, and got an impressive amount of exercise climbing mountains and clearing trails.

        Her death has left her many friends wondering “why her?” Her example undercuts the notion that any of us can ultimately do much to avoid an ugly death from cancer.

        So after living the healthiest life you can imagine, she spent her last days coping valiantly with the debilitating effects of the best cancer therapy her doctors could offer. It wasn't enough.

    • Dazy Dazy

      The new John Hopkins (cancer research institute) study is being misinterpreted on standard media, of course. The last sentence or two in the study states that dna mutations during replication that go cancerous are a direct result of hazardous contaminants in our environment or unhealthy lifestyle choices (which mean contamination as well).

      The solution is the cure, eliminate environmental toxins of the man made variety from our environment. That is the only cure for cancer.

      My condolences for you beautiful friend, Jebus.

      Fatal Fallout…its great to have a whole documentary on this. Too bad they got the 9-11 WTC thing wrong from the start.

      Unless the science world embraces the findings of Bandazhevsky and other researches which form the basis for the ECRR dose coefficients, its all for naught. The realization that man made nuclear radiation is orders of magnitude more toxic per becquerel than background radiation is something that very few realize. The simple equation of radiation quantity = toxicity quantity is an unfortunate belief that undermines the entire anti nuclear effort

  • SadieDog

    "STRICKLER — Work began this month to assess the level of radioactivity remaining at the heart of a shuttered nuclear reactor test site in rural Washington County.
    The findings will determine the waste classification for the site's reactor vessel. But actually removing the vessel will take another $16 million in federal funding, said Mike Johnson, associate vice chancellor for facilities at the University of Arkansas, Fayetteville, which owns the site.
    "I'm very optimistic we'll get those additional funds," said Johnson, adding that an announcement could be made in late spring or early summer.
    He said a fully funded cleanup would allow the site to return to "green field" status next year, but a lack of additional funds would cause cleanup to stop at the end of September after a partial demolition.
    Ongoing cleanup began about three months ago after a $10.5 million grant announced in September by the U.S. Department of Energy."

    "While performing a purification subsystem alignment on the Unit-2 Refueling Water Tank, an inadvertent transfer of Refueling Water Tank level to the common Spent Fuel Pool occurred.

    This transfer resulted in lowering Unit-2 Refueling Water Tank level below the Technical Specification [TS] required limit for the current mode of operation at 0142 [EDT] on 3/25/17.

    Upon recognition of the inadvertent transfer, Operations secured the lineup and restored Unit-2 Refueling Water Tank level to its normal operating band at 0225 on 3/25/17.

    "This event is reportable under 10 CFR 50.72(b)(3)(v)(D) '…any event or condition that at the time of discovery could have prevented the fulfillment of the safety function structures or systems that are needed to mitigate the consequences of an accident.'

    With less than the required Technical Specification volume in the Refueling Water Tank, insufficient volume existed in the Refueling Water Tank to maintain 30 minutes of full flow Safety Injection, and subsequent continued pump operation after transition to recirculation mode of operation."

    This level is required by Technical Specification 3.5.4.B and has a one hour action statement to restore level.

        "On February 3, 2017, Prairie Island staff performed maintenance on the transom above Battery Room Door 225.

        This activity resulted in the transom being unlatched for approximately five minutes. On February 6, 2017, a question from the NRC Resident Inspector resulted in an evaluation of this condition for past operability. [ NRC insp. aware of this activity ]

        On March 20, 2017, the past operability evaluation of Door 225 concluded that, in the event of a postulated HELB [High Energy Line Break], the transom being unlatched during the five minute maintenance period resulted in the inoperability of multiple systems in the Unit 1 and Unit 2 battery, auxiliary feedwater, and Unit 1 safeguards bus rooms that would be required to mitigate the postulated HELB.

        "The loss of safety functions required to mitigate the postulated HELB make the condition reportable under 50.72(b)(3)(ii) for an unanalyzed condition that significantly degrades plant safety.

        "Unlatching the transom above the Battery Room Door creates an opening not accounted for in design bases documents.

    Nuclear Radiated Japanese Food Removed From Shops in China

    Food in Muji was tagged with Chinese labels. The country of origin on the label was Japan. Market and Quality Supervision Commission of Shenzhen Municipality found that after removing the Chinese label on the package, it showed that the food was produced in Tokyo, which is in the list of Import Forbidden Countries published by General Administration of Quality Supervision, Inspection and Quarantine (GAQSIQ).

    AEON Supermarket in Shenzhen was also found selling rice produced in Niigata-ken. Another company of Shenzhen also admitted selling Calbee cereal which was produced in nuclear radiated area. Over 20,000 bags of Calbee cereal were found in the warehouse in Tianjin.

    After the earthquake and tsunami on 11 March 2011 damaged the Fukushima Dai-ichi Nuclear Power Plant (FDNPP), an accidental release of a large amount of radioactive isotopes into both the air and the ocean occurred. Measurements provided by the Japanese agencies over the past 5 years show that elevated concentrations of 137Cs still remain in sediments, benthic organisms, and demersal fishes in the coastal zone around the FDNPP. These observations indicate that there are 137Cs transfer pathways from bottom sediments to the marine organisms. To describe the transfer quantitatively, the dynamic food chain biological uptake model of radionuclides (BURN) has been extended to include benthic marine organisms. The extended model takes into account both pelagic and benthic marine organisms grouped into several classes based on their trophic level and type of species: phytoplankton, zooplankton, and fishes (two types: piscivorous and non-piscivorous) for the pelagic food chain; deposit-feeding invertebrates, demersal fishes fed by benthic invertebrates, and bottom omnivorous predators for the benthic food chain; crustaceans, mollusks, and coastal predators feeding on both pelagic and benthic organisms. Bottom invertebrates ingest organic parts of bottom sediments with adsorbed radionuclides which then migrate up through the food chain. All organisms take radionuclides directly from water as well as food.

    The return of Yucca Mountain should be the clarion call that unites Nevada in demanding that the federal government give us back our land.

    As the Nevada Land Management Task Force noted in 2014, the federal government owns 87 percent of the land in Nevada. That’s by far the highest of any state. Since Nevadans are less than 1 percent of the U.S. population, politicians in Washington D.C. face little electoral risk for putting nuclear waste in our basement. After all, they own it and most of the rest of Nevada.

    Federal land ownership isn’t just a Nevada problem. In the 12 Western states, the federal government owns an average of 50 percent of the land. Average federal land ownership in states east of the Rockies is less than 5 percent.

      Kevin Blanch…its unfortunate; he NEEDS the ECRR, Busby and the VITAL information that low level nuclear fallout is 300 to 1000x worse than assumed by the ICRP LNT standards. That raising of safety standards by the EPA is interesting but its not the way to fight the real problem. Its not enough

      Blanch is very confident he can argue against that article about the Livermore group etc, but in fact its the same story we ALWAYS get. What story? That the LEVELS of radiation or LOW, much less than BACKGROUND radiation and scientifically agreed harmless.

      The arguing point is that the nuclear fallout is not the same as background…cesium-137 is not potassium-40, plutonium is not radon, strontium is not a cosmic ray. They LOOK similar on paper, as measured and defined…alpha, beta, gamma etc, but they arent the same at all, most conspicuously the element, its atomic number and the specific activity. This is where the anti nukers fail. Everybody buys into the radiation quantity = danger trap. The result is they lose against the scientific status quo.

    Fukushima Daiichi Status Updates

    On 3 April 2017, Japan provided the IAEA with a copy of a report on the discharge record and the seawater monitoring results at the Fukushima Daiichi Nuclear Power Station during March, which the Ministry of Foreign Affairs has sent to all international Missions in Japan.

    The report contains information on discharges from the subdrain and groundwater drain systems, as well as on groundwater bypassing conducted during the month of March. In both cases, in advance of the action, TEPCO analyzes the quality of the groundwater to be discharged and announces the results. These results confirm that the radiation level of sampled water are substantially below the operational targets set by TEPCO.
    https://www.iaea.org/sites/default/files/mfa-information-170403.pdf

    • HillbillyHoundDog HillbillyHoundDog

      "…operational targets set by TEPCO (these operational targets are well below the density limit specified by the Reactor Regulation). The results of these analyses were also confirmed by third-party organization (Mitsubishi Nuclear Fuel Co., Ltd, Kaken Co., Ltd and Tohoku Ryokka Kankyohozen Co.).
      In addition, TEPCO and Japan Atomic Energy Agency (JAEA), at the request of the Government of Japan, regularly conduct more detailed analyses on the purified groundwater. The results of JAEA’s latest analyses confirmed that TEPCO’s analyses were accurate and verified that the radiation levels of sampled groundwater is substantially below the operational target (see Appendix 2). …"

      Targets set by Tepco. Confirmed by the nuclear mafia.

      Nowhere in the "report", was there any information on the volume of the discharges.

      …Tepco has been advertising "ND" in port samples for quite some time now. I don't buy it. They lie and how is that even possible??

      • freebywill

        I read that report also HHD and found it to be unbelievable for several reasons.

        In the report it states:
        ND represents a value below the detection limit; values in ( ) represent the detection limit.

        I would think the detection limit would be stable but it varies.

        Mitsubishi Nuclear Fuel Co., Ltd is one of the third party analyzers.

        Disparity between WHO limts and Reactor Regulation.

    "Ikeda’s work at the plant was as varied as it was hazardous. At one point he helped construct a facility to dispose of workers’ TyVek suits, the ubiquitous white hooded jumpsuits that after exposure to radiation were discarded onto mountainous piles inside the plant’s evacuation zone.

    Later he was involved in the construction of a temporary elevator at shattered reactor 3 and a 50-meter-tall heavy-duty steel structure to surround reactor 4 and support a huge overhead crane that was needed to remove the smoldering fuel assemblies in the fuel pool. These had been exposed to the elements following an explosion that blew away the reactor roof and the original crane.

    Long ways to go, but stick a fork in this chapter.

    The company contracted to build Scana Corp.’s two nuclear reactors in South Carolina went bankrupt. Scana’s credits ratings are, as a result, at risk of downgrades. Its shares have plunged.

    And now some of the people hired to help finish the reactors aren’t showing up for work.

    In a meeting Wednesday, Scana executives assured South Carolina regulators that work continues on the two reactors being installed at its V.C. Summer plant, despite Toshiba Corp.’s Westinghouse Electric unit filing for Chapter 11 last month. But the Cayce, South Carolina-based utility owner also said Westinghouse is cutting weekend and overtime work and that contractor Fluor Corp. has seen a “high incidence” of new hires failing to show up for training since Westinghouse went bankrupt.

    Nuclear Giants Limp Towards Extinction | http://www.ecowatch.com/nuclear-energy-collapse-2360633461.html

    [ excerpted ]

    Any lingering hope that a worldwide nuclear power renaissance would contribute to combating climate change appears to have been dashed by U.S. company Westinghouse, the largest provider of nuclear technology in the world, filing for bankruptcy, and the severe financial difficulties of its Japanese parent company, Toshiba.

    Toshiba and Westinghouse are in deep trouble because the reactors they are currently building—the same design as the ones planned for Cumbria—are years late and billions of dollars over budget. Even if the companies can be refinanced, it seems extremely unlikely they would risk taking on new reactor projects.

    Despite the fact that there are more than 430 nuclear reactors in operation worldwide and the industry still has great economic and political clout, it is beginning to look like a dinosaur—too big and cumbersome to adapt to new conditions.

    Nuclear power now produces about 10 percent of the world's electricity, while 40 percent is from coal and 23 percent from renewables. The rest is mainly from natural gas. [ 27 percent ]
