    US_NPS Vogtle 3;4 (GA) under construction FITNESS-FOR-DUTY REPORT

    "On May 17, 2017, at 1852 [EDT], Southern Nuclear Operating Company (SNC) contractor informed SNC that a contractor Fitness-for-Duty (FFD) collector failed to follow the process defined in both NRC Regulation 10 CFR 26.105(b) and contractor FFD procedures.

    The collector was fully trained, qualified, and knowledgeable of the process requirements.

    This determination was made based on initial department investigations and corroborated via independent investigations performed by the contractor.

    SNC has determined that this is reportable under 10 CFR 26.719(b)(3)."

        * * * RETRACTION FROM DAVID ALLEN TO S. SANDIN ON 5/18/17 AT 1459 EDT * * *

        "Event Notification EN 52669, made on 4/06/2017, is being retracted because additional reviews have been performed supporting that a loss of safety function did not occur.

        "Watts Bar Unit 2 has concluded that there was no loss of safety function, because when the door was found open it was capable of being closed and able to support the control room envelope function. A simulation performed on 04/07/17 also showed that with the door in question opened 1-2 inches that the control room pressure would have remained above the TS required positive pressure of 0.125 inches of water.

        "The control room envelope is designed such that the door is expected to be opened to allow personnel entry and exit, and thus positive pressures in the control room will fluctuate. The event that occurred is similar to a number of individuals entering and exiting the control room in series. Since the control room envelope function was not lost, this event is not reportable and NRC Event Number 52669 is being retracted. The basis for this conclusion will be provided to the NRC Resident Inspector."

    Sample pic of the speadsheet I developed to track reactor activity

    Data sources are the daily NRC Event Notice reports and Reactor Status reports.

    This dataset is for commercial nuclear poison spewers (NPS).

    There are a bunch of research and test reactors at colleges and other gov't locations but info on daily operations are non existent.

    • free– just an idea, and of course I am sure you have many hours into developing that spreadsheet.

    Public Trails on Radioactive Land Called a Bad Idea

    EMMA GANNON May 19, 2017

    DENVER (CN) — The Rocky Flats Wildlife Refuge, with public trails on nearly 5,000 acres of some of the radioactively polluted land in the nation, at an old nuclear weapons plant, should not open until the secretary of the interior can certify it is safe, five environmental groups say in a federal lawsuit.

    “Rocky Flats is among the nation’s most polluted places,” the complaint states. “Its name is synonymous with plutonium, a laboratory-developed, radioactive chemical element that was used at the facility to produce nuclear triggers for almost 40 years during the Cold War. After the FBI raided Rocky Flats and the operators’ mismanagement and misconduct was exposed, a federal jury in Cook v. Rockwell found that Rocky Flats plutonium had migrated onto neighboring properties, where it will remain ‘indefinitely,’ causing an ‘increased risk of health problems.’ The case concluded in 2016 with a settlement of $375 million to Rocky Flats’ original neighbors.”

    "… 15,000 homeowners near the site, 27 miles northwest of downtown Denver, were awarded an average of $25,000 apiece …"

    The Fish and Wildlife Service does not comment on pending litigation.

    Cleanup at Idaho nuclear landfill on hold after pit collapse

    UPDATED: Thu., May 18, 2017, 10:57 p.m.

    “Our crews had been exhuming waste for about 30 minutes when a portion of the pit wall where the excavator was operating sloughed off and the excavator slid into the pit,” said Simpson. “We’re working on a path to remove the excavator from the edge of the pit and basically make some additional enhancements to protect the operators and the excavators from this point forward.”

    The excavator was digging inside a large building at the 97-acre Subsurface Disposal Area when the side of the pit collapsed. The pit is about 21 feet deep, and the operator remained inside his protective cab for about 90 minutes afterward while crews worked to make sure it was safe for him to leave.

    Conservative election manifesto signals the end of new nuclear power

    Oliver Tickell & Ian Fairlie

    18th May 2017

    After years of pro-nuclear bombast from the Conservative Party, its 2017 manifesto hasn't got a single word to say about nuclear power, write Oliver Tickell & Ian Fairlie. Instead it announces a renewed focus on cutting energy costs, and a big boost for increasingly low-cost wind power; while both Labour and Libdems offer only weak, highly qualified support for new nuclear build. And so the great British 'nuclear renaissance' reaches its timely end.

    By Christine Legere

    PLYMOUTH — Pilgrim Nuclear Power Station continues to fall short, according to the quarterly inspection report published by the Nuclear Regulatory Commission this week.

    Issues range from failure to comply with federal requirements for reporting incidents to lack of a long-term solution for disintegrating panels whose job is to prevent a nuclear reaction from occurring in the spent fuel pool.

    “If Pilgrim was a horse, it would have been shot and put down by now,” David Lochbaum, director of the Nuclear Safety Program for the Union of Concerned Scientists, wrote in reaction to this latest report.

    More than 1K metric tons of spent uranium fuel still in temporary storage in Nebraska

    NICHOLAS BERGIN Lincoln Journal Star May 18, 2017

    Fort Calhoun Nuclear Station powered kitchen blenders, cash registers and televisions in eastern Nebraska for more than four decades by harnessing the energy released by splitting uranium atoms.

    Deemed too expensive to keep running, the power station’s generators ceased spinning Oct. 24. Yet a highly radioactive legacy remains.

    Spent fuel rods — nuclear waste potent for thousands of years — will remain along the Missouri River’s west bank for the foreseeable future.

    Fort Calhoun and the larger still-operating Cooper Nuclear Station, south of Brownville, had 1,010 metric tons of used uranium fuel in temporary storage as of February, according to the Nuclear Energy Institute.

      Anyone know how many kilowatts are used to keep a spent fool pool operating ?

      • Down The River Down The River

        Good question freebywill. It’s probably in the megawatt range.

        I have always wondered how much electricity an NPP complex uses when it’s not generating power. The lighting alone must use several megawatts.

        I have tried looking into this, but no luck finding anything. This information is not readily available.

      • free– BTW loved that spreadsheet screen cap on how you pull data into the spreadsheet on Nuke reactor operations and problems. I assume it is mostly automated, like just an F9 is needed?

        RE cooling pool and other energy to store spent fuel…you could try asking the NRC directly at their blog. Somehow they took me off their email list, imagine that.

        Here is the open forum

        • Down The River Down The River

          Might be a good idea stock, but I’m a bit apprehensive about asking technical questions on the NRC blog, I may not like who shows up at my front door.

    “It’s just a very sad thing, and I think it’s not only going to affect us economically, but socially the town will change as well,” he said. “Since it’s going to be pretty much summer home owners and summer rentals. And we’re going to miss that neighborhood and that community feel.”

    Other residents are happy to see the plant go. Palisades is one of the oldest nuclear plants in the country and has had several emergency shutdowns."

    Didn't happen. It's been more than five years now. Does no one in media do follow ups? I guess they just say what they are told. Calms the masses. Yeah. They are doing all they can. Now they are going to dump 920,000 tons of radioactive water in the ocean. This proves it, they DO care.

      Forest fires in Fukushima Forests. Monkeys used the smoke as a cover, broke into Fukushima University and stole radiation monitors. Hacked in and uploaded the readings. Police are investigating. Monkeys are now crowded in with Julian Assange making life in the embassy very crowded. USA seeks extradition.

    • FaunaLord Farthington MacMananus

      In more important news, tame mutated degenerate monkeys don't even have to be fitted with radiation monitors. A cost analysis has deemed the radiation monitors to be unprofitable when a clearer assessment could be done by studying epidemoliogical damage and correlating it observed and predicted models in more localized trials.

      A recent study shows:

      In some cases, the recently propagated GMO variety of degenerate monkeys (homo-socioincorporatem) even promote nuclear radiation, while being subjects for testing and validating effects, adding to the overall worth and value added benefits of the nuclear industry and cancer racketeering as the industries are closely related with significant support from agriculture, "national interests" in the form of government, psychiatry, big pharma, the military industrial complex, the popularized entertainment industry, by fully utilizing these simple, disposable assets.

      For more information, each asset is accordingly assigned a UUID so as to not produce ambiguity in our optimized databasing and you could access this information given sufficient clearance and a suitable fee.

        Funny they said they were going to use the monkeys in 2011, but in 2013:

        "In the eastern part of Fukushima Prefecture, including the restricted areas, about 3,000 Japanese monkeys have been identified [12]. However, scientists are not currently permitted to enter the restricted areas for animal research. "

      • unincredulous unincredulous

        Monkeys only live to about 20 years old the article says. We should see generational mutations more easily with the species. You would think "scientists" would be trampling each other to gather data in the restricted zone. After all, they say there are a thousand or so workers at the FDNPP working all the time. And they announced that full protective gear is no longer required in many areas at the power plant.

        • unincredulous unincredulous

          …and they ARE gathering the shit out of data on the monkeys. The health of the monkeys, but the radiation readings at various levels in the canopy, and on the ground in the forests and mountains is what the articles said they would be providing.

          And I bet they have the data but we don't see any articles with those results. Maybe somewhere behind a pay wall.

            It would help us to be rational if they would stop lying and hiding data all the time. So "irrational" I will be

      • unincredulous unincredulous

        The monkeys "don't have to be fitted"

        No, but the stated purpose of using the monkeys was to measure radioactivity in various levels of the canopy of trees.

        I bet they just don't want to get into the embarrassing situation of showing how many of the monkeys die. We know they have high levels of radioshit in their bodies. Higher than 100 bq/kg. Eating the monkeys would not be within safe limits, so we know they are suffering

    What the hell is this? A possible close call at Columbia in Dec 2016 revealed in yesterdays retraction.

    Original EN
    "On December 18, 2016 at 2320 [PST], a leak was discovered on the High Pressure Core Spray (HPCS) system minimum flow line.
    The leak is located at a bolted flange downstream of the manual isolation valve HPCS-V-53.
    The location of the leak is not isolable from the suppression pool.
    This provides a direct path from inside the Primary Containment to the Reactor Building.



    "Engineering evaluations indicate that there was neither a High Pressure Core Spray (HPCS) system inoperability nor a condition that resulted in a significantly degraded principal safety barrier (Primary Containment). Therefore, this event does not meet the reporting criteria in 10 CFR 50.72(b)(3)(v)(D) and 10 CFR 50.72(b)(3)(ii)(A), and Event Notification# 52443 is being retracted.

    "Bases [sic] [Basis] for the retraction are:

      (2) the consequences of the HPCS Minimum Flow Line leak into the Reactor Building were within the dose limits and did not have a significant effect on Primary Containment integrity;

    My pizza is done. I could not turn the oven off. Firefighters were called. They pumped 80 tons of water per second into the oven three days later. They are still pumping. I can't find my pizza. The oven blew up. I looked and the pizza is not in there. Must be down in the broiler. I'm sure of it. Pepperonis all over the yard. Cheese on the neighbors' window. The neighborhood was evacuated. Strong odor of pizza and the firetrucks out on the lawn. Heat waves coming out of my apartment. The lawn is flooded. I keep telling the neighbors they should come back. They won't be mad at me will they? It wasn't my fault. I will send them a bill for their trouble. I gave one neighbor a Coke. Keep waiting but the asshole hasn't returned the favor.

    So, what's new? Can I come over and cook you a pizza?

    US nuclear regulators greatly underestimate potential for nuclear disaster

    The US Nuclear Regulatory Commission relied on faulty analysis to justify its refusal to adopt a critical measure for protecting Americans from nuclear-waste fires at dozens of reactor sites around the country, according to a recent article. Radioactivity from such a fire could force approximately 8 million people to relocate and result in $2 trillion in damages.

    This image captures the spread of radioactivity from a hypothetical fire in a high-density spent-fuel pool at the Peach Bottom Nuclear Power Plant in Pennsylvania.

    In this scenario, which is based on real weather patterns that occurred in July 2015, four major cities would be contaminated (New York City, Philadelphia, Baltimore and Washington, D.C.), resulting in the displacement of millions of people.

    Published by researchers from Princeton University and the Union of Concerned Scientists, the article argues that NRC inaction leaves the public at high risk from fires in spent-nuclear-fuel cooling pools at reactor sites.

    Nuclear power is so expensive even some conservatives are turning on it

    Nuclear power is so expensive even some conservatives are turning on it The nuclear industry is so uncompetitive that half of U.S. nuclear power plants are no longer profitable. And if existing nukes are uneconomic, it’s no surprise that new nuclear plants are wildly unaffordable.

    New York and Illinois have already agreed to more than $700 million a year in subsidies, and if all northeast and mid-Atlantic nukes got similar subsidies, it would cost U.S. consumers $3.9 billion a year. Things are so bad for the nuclear industry that, recently, even conservatives have started to publicly oppose the subsidies the industry needs to survive.

    “Ever since the completion of the first wave of nuclear reactors in 1970, and continuing with the ongoing construction of new reactors in Europe, nuclear power seems to be doomed with the curse of cost escalation,” explained one 2015 journal article, “Revisiting the Cost Escalation Curse of Nuclear Power.”

    Deconstructing Pilgrim: The will of the people

    By Diane Turco

    Cape Codders take the lead once again. Last week, votes tallied in all Cape towns (except for Barnstable due to fall elections) showed citizens overwhelmingly support a call for public safety. This ballot initiative called on Governor Charlie Baker to speak out as chief safety officer to ensure that high level nuclear waste now stored in the vulnerable spent fuel pool at Pilgrim be moved to safer dry cask storage. Understanding the dangers, citizens demand our government protect us.

    Back in 2013, every Cape Cod town voted for then-Governor Deval Patrick to call for immediate shutdown of Pilgrim. These townspeople understood the serious threat Pilgrim presents to our communities. But Patrick did not respond for months. After much public pressure, a State House rally and sit-in at the governor’s office, Patrick finally sent notice to the Nuclear Regulatory Commission. Even with the citizen vote, it took direct action to move Patrick in the right direction.

      Cape Downwinders Promote Voter Initiative to Move Nuclear Waste

      PLYMOUTH –The Cape Downwinders initiated a Non-Binding Public Advisory Question Campaign this spring that passed in 14 Cape Cod towns.

      The question is expected to be brought to Barnstable voters at fall election.

      The effort is meant to be a citizen’s petition to Governor Charlie Baker to speak up for public safety.

      According to the group, the campaign is aimed at alerting citizens of the ongoing dangers presented by the Pilgrim Nuclear Power Station in Plymouth.

      The Downwinders are also encouraging the newly formed Nuclear Decommissioning Citizens Advisory Panel to take on the challenge as a first step to safer and secure on-site waste storage.

      The panel’s first meeting is Wednesday night in Plymouth.

    EBR-I museum opens Friday

    Idaho National Laboratory’s historic Experimental Breeder Reactor-I Atomic Museum opens Friday.

    The EBR-I museum, located 50 miles west of Idaho Falls off U.S. Highway 20, is open from Memorial Day weekend through Labor Day weekend. Guided and self-guided tours are available. It is open from 9 a.m. to 5 p.m. seven days a week.

    EBR-I was completed in 1951 and was the first nuclear reactor to produce a usable amount of electricity. It was operated until 1963. President Lyndon Johnson dedicated the reactor as a Registered National Historic Landmark in 1966. It is one of 10 National Historic Landmarks in Idaho.

    The museum also includes displays on EBR-I’s sibling, Experimental Breeder Reactor-II, which once powered most of the site.

    Highlights of public comments on Edison's plan to store 3 tons of nuclear waste on the beach at San Onofre, from the May 11, 2017 Citizen Engagement Panel meeting in Laguna Hills, CA.

    Local residents agree its a crazy plan and want it moved. But a proposal by two corporations to ship it to Texas or New Mexico for private profit is equally crazy, says visiting Texas activist Karen Hadden.

    Its a problem that will be faced by over 100 other reactor communities across the country as aging US nukes are increasingly shut down.

    House Democratic leaders question Millstone’s need for state assistance

    May 26, 2017 11:34PM
    By Eric Bedner Journal Inquirer

    Dominion officials have said that they are not immune to the same issues that have led to the closing of nuclear power plants throughout the country, but they are not required to disclose their finances in order to pass the bill.

    Critics have said the power plant is not in substantial financial trouble, citing a Massachusetts Institute of Technology study determining that Millstone is on pace to become the nation’s most profitable nuclear plant in the country in upcoming years.

    While Aresimowicz said he is sensitive to the fact the facility provides about half the state’s total power, he’s not in favor of passing legislation simply to help Dominion increase its profits.
