    "At 0204 [CDT] on 5/3/2017, a facilities person was removing the trash bags from the garbage can in the restroom of the Administrative Building inside the Protected Area.

    While emptying the trash, they discovered a 100ml alcoholic beverage container in the trash.

    The container was empty, however, there was an odor of alcohol coming from the bottle.

    The item was turned over to the security department.

    The investigation identified the last time this trash bag had been changed out was on 5/2/2017 at 1530 [CDT].

    This event is being reported per 10CFR26.719(b)."

    "On April 30, 2017, at 1818 [EDT], the main turbine steam bypass valve #1 partially opened.

    Power was incrementally lowered.

    While lowering power the bypass valve would shut and then reopen and power would again be lowered.

    When power was lowered to approximately 74 percent the bypass valve remained closed.

    During the transient the reactor protection system (RPS) Turbine Stop Valve Closure and Control Valve Fast Closure trip functions were declared inoperable due to the opening of the bypass valve which affects the bypass setpoint for those RPS trip functions.

    With the loss of these RPS trip functions a loss of safety function existed intermittently for approximately 37 minutes.

    The manual reactor trip function and other RPS functions remained operable.

    "Both channels of the rod withdrawal limiter (RWL) and the end of cycle reactor recirculation pump trip (EOC-RPT) function were also declared inoperable.

    These functions are credited in accident analysis, this also resulted in a loss of safety function.

    "Currently the bypass valve is closed and the RWL, EOC-RPT and RPS function are operable.

    Troubleshooting continues to determine the issue with the main turbine that caused the bypass valve to open."

    …The commercial start-up of the first of four nuclear reactors that South Korea's KEPCO is building in United Arab Emirates is set to be delayed because the local operating company is not ready to run the reactors, a nuclear industry source said.

    …But a source familiar with the situation said that Nawah – the joint venture between the Emirates Nuclear Energy Corporation (ENEC) and KEPCO that will operate the plant – is struggling to get an operating license, which could delay the start-up of the first plant by several months, possibly to the end of this year.

    LOWER ALLOWAYS CREEK TWP. — A worker "deliberately" attempted to fix an error he had made while conducting tests at a New Jersey nuclear reactor causing the plant to shut down 2 years ago, federal officials say.

    The now-former employee's action prompted the Hope Creek generating station to automatically shut down on Sept. 28, 2015. The worker later lied about what he did, officials said Wednesday.

    Sheehan said the utility will not be fined in the case, citing the utility's investigation that uncovered what the technician did and the company's prompt reporting of the findings to the federal agency. Sheehan said, however, said the NRC will be following up closely to be sure PSEG Nuclear puts procedures in place to prevent this from happening again.

    The ex-worker won't be subjected to any penalties from the NRC and won't be barred from working at another nuclear plant, according to Sheehan.

    "Despite their modest power output, the Gabon nuclear reactors are remarkable because they spontaneously began operating around two billion years ago, and they continued to operate in a stable manner for up to one million years. Further, at the Gabon reactors many of the radioactive products of the nuclear fission have been safely contained for two billion years, providing evidence that long-term geologic storage of nuclear waste is feasible."

    What's it like to work in a nuclear plant? "“We’ve been saying it for years: ‘NRC stands for Nobody Really Cares,’ ” one reactor operator said."


    "[...] Paul held it together until the holidays, when operator vacation time is at its highest and the shift work schedule descends into chaos. By January, Paul was exhibiting persistent flulike symptoms. He started to drop weight, eventually losing almost 40 pounds (18 kg). He hung cardboard in his windows at home to keep the sunlight out. He migrated from couches to beds in search of sleep, but very little came.

    This went on for three months before Paul hanged himself in the shed behind his boyhood home."

    "On 5/4/17 at 2103 CDT, the South Texas Project [STP] Security Department was conducting on-the-job training for Bomb Threat response.

    While simulating the Bomb Threat Checklist via phone call, the trainer mistakenly contacted the Brazoria County, TX Child Protective Services (CPS) and reported a bomb threat.

    In response, the Child Protective Services notified the City of Brazoria, TX Police Department of the threat.

    The Brazoria Police Dept. then contacted both the Bay City, TX Police Department and the STP Security Department.

    "Ametek Solidstate Controls began a 10 CFR Part 21 evaluation after receiving notification from NextEra Energy Seabrook Station that a 7.5kVA Inverter would prematurely transfer to alternate source at 27A load during commissioning. The X202 Crest factor board (80-9213516-90) was replaced and the unit operated normally.

    "Analysis of the failed X202 Crest Factor board identified an SCR on the printed circuit board was turning on prematurely and resulted in a transfer to alternate source or with the absence of the alternate source, to a dead bus. A capacitor was placed across the SCR on the X202 board to protect the SCR from dv/dt turn on. Subsequent testing determined the added capacitor corrected the anomaly.

    "In addition to Seabrook, Ametek has recently experienced similar anomalies on two separate occasions. However, these occurrences were discovered during manufacturing and in-house testing phase for new product and were attributed to a SCR failure, excessive noise, and long leads.

    Ametek Solidstate Controls recommends installing a 0.22 microfarad capacitor p/n 80-134734-90 across X202 terminals J1-11 to J1-12. This capacitor will have no effect on EMI or seismic qualifications.

    Emergency declared at US Hanford nuclear waste site after tunnel collapse

    About 3,000 workers have taken cover at the 200 East Area of the sprawling complex, local media reported. By 10:30 am local time, the “take cover” orders have been expanded to the entire site, which is about half the size of Rhode Island.

    The PUREX facility was built in the 1950s and used until 1988 to extract plutonium from around 70,000 fuel rods in total. The building has been vacant for nearly twenty years and “remains highly contaminated,”according to the Hanford website. Rail cars used to transport the fuel rods from the nuclear reactors to the processing facility are buried inside the nearby tunnels.

    “In the ‘60s, spent fuel rods were put in railroad cars and, once filled, the railroad cars were wheeled into a tunnel dug into the side of a hill,” Bradbury said. “Twenty-eight rail cars in all fill this particular tunnel. "

    " officials have detected no release of radiation. "
    [ just like they detected no release at WIPP, TMI, Chernobyl, Fukushima - then later when they turn on the detectors they'll detect only a slight increase and the people nearby who suddenly develop unexplained illness will be told it has nothing to do with the incident ]

      "Nuclear power is so expensive compared with other forms of energy that it has become “really hard” to justify, according to the chief executive of General Electric, one of the world’s largest suppliers of atomic equipment.

      “It’s really a gas and wind world today,” said Jeff Immelt, referring to two sources of electricity he said most countries are shifting towards as natural gas becomes “permanently cheap”.

      “When I talk to the guys who run the oil companies they say look, they’re finding more gas all the time. It’s just hard to justify nuclear, really hard. Gas is so cheap and at some point, really, economics rule,” Mr Immelt told the Financial Times in an interview in London at the weekend. “So I think some combination of gas, and either wind or solar … that’s where we see most countries around the world going.”

      ADAMS: "Disclosure: I attended the event described below as a holder of one of the hundreds of recently created high-tech jobs at B&W."

      ("The advanced manufacturing technologies B&W will use to produce nuclear fuel for its B&W mPower small modular reactor (SMR) will be developed and qualified at the FTC. Longer term, the technologies developed at the FTC give B&W the ability to support the manufacture of fuel for other reactors.")

However, Summerill failed to properly implement the requirements of NCA-3855.5(a)(2) in that a product analysis of each piece of unqualified source material was not performed.

    "Tioga Pipe does not have the capabilities to conduct an evaluation of the defect to determine if a substantial safety hazard exists in the tubing supplied to Duke/Progress Energy.

    Closure of Indian Point Nuclear Plant Faces GOP Hurdle

    ADAM KLASFELD May 12, 2017

    WHITE PLAINS, N.Y. (CN) — A troubled nuclear plant near New York City could remain open beyond its scheduled closure date of April 2021 if a Republican politician’s new lawsuit forces further environmental review.

    If successful, Westchester County Executive Rob Astorino’s legal challenge would sink plans to shutter Indian Point Energy Center and force its owner Entergy to pay $15 million for environmental and community funding.

    Astorino claims in his May 9 lawsuit in Westchester County Supreme Court that New York’s State Environmental Quality Review Act findings looked into only the impact of the plant’s continued operation, not the secondary effects its closure would have on jobs, costs, spent fuel and greenhouse gases.

      "On May 15, 2017 at 1800 hours EDT, the '2A3' 4.16 KV safety related bus unexpectedly de-energized.

      The '2A' emergency diesel generator (EDG) system received a valid start signal from the undervoltage condition on the '2A3' bus but did not start as the EDG had been removed from service for maintenance.

      Loss of the '2A3' 4.16 KV bus resulted in a valid actuation of the undervoltage protection relays.

      The direct cause of the de-energization was determined to be failed secondary side potential transformer fuses.

      The 'B' train safety related electrical busses were unaffected by the event.

      "The '2A3' 4.16 KV bus was reenergized at 2340.

      "This event was determined to be reportable pursuant to 10CFR50.72(b)(3)(iv)(A)."

      During the electrical transient, the licensee briefly entered Technical Specification 3.0.3 but plant conditions were restored, all required LCOs were satisfied, and Technical Specification 3.0.3 was exited before the plant was required to downpower.

        "This letter is issued to provide an interim notification of a potential defect in certain lots of Grayboot socket contacts supplied with EQ qualified Grayboot Connector Kits.

        On March 16, 2017, Curtiss-Wright, Nuclear Division, Huntsville Operations was contacted by Georgia Power Vogtle Nuclear Power Plant concerning a potential defect where the socket contact tines were in a relaxed state.

        [ This may be related to the EQ in Feb ]

        "Although we have completed some testing and verification activities, additional testing is in progress now and will provide necessary information to complete our evaluation. Current testing will be completed and final conclusions made by May 31, 2017.

        "At this time, based on test results, evaluations and operating experience, Curtiss Wright is confident that any potentially affected Grayboot Assemblies will continue to perform their intended safety functions. As such, if the final recommendation is to replace the potentially defective socket contact, this can be accomplished during subsequent routine maintenance activities.

          * * * RETRACTION AT 1652 EST ON 5/15/17 FROM JEFF YEAGER TO JEFF HERRERA * * *

          "The purpose of this notification is to retract a previous report made on March 30, 2017 (EN 52651). The notification to the NRC involved an event where secondary containment momentarily exceeded the Technical Specification (TS) requirements during refueling activities which had been designated as operations with the potential to drain the reactor vessel (OPDRVs). The notification was made under 10 CFR 50.72(b)(3)(v)(C) as an 'event or condition that could have prevented the fulfillment of the safety function of structures or systems that are needed to … control the release of radioactive material.' Subsequent to the initial notification, the event and the NRC guidance in NUREG-1022 pertaining to 10 CFR 50.72(b)(3)(v) were reviewed further. At the time of the event, Fermi 2 was shutdown (Mode 5. Refueling). In Mode 5, the pressures and temperatures that could cause a loss of coolant accident (LOCA) are not present. No movement of fuel was in progress such that the fuel handling accident (FHA) was also not applicable. Thus secondary containment was only required per TS due to the ongoing OPDRVs. The Fermi 2 UFSAR does not describe OPDRVs as an accident that secondary containment is required to…

    Fukushima's Harsh Warning – Chris Busby

    while declaring "False" the assertion that Fukushima reactors are falling into the ocean, Snopes uses statements from TEPCO, and The Gaurdian UK.

    But The Gaurdian states, "So much of what is communicated to the public and media is speculation and wishful thinking on the part of industry and government." The Gaurdian also quotes a nuclear engineer :"Mitsuhiko Tanaka, a former Babcock-Hitachi nuclear engineer, accuses Abe and other government officials of playing down the severity of the decommissioning challenge in an attempt to win public support for the restart of nuclear reactors across the country."

    So here is a question for Snopes: Is TEPCO a bunch of lying industry shills?

      The Snopes article : :Will Davis, a consultant and author in the nuclear energy field and former US Navy Nuclear Reactor Operator, told us the alarm raised in many media reports about the finding is unwarranted. Radiation levels are not spiking — Tepco has been searching for damaged fuel and found it, so a high reading at the specific location was to be expected and further, it is safely contained:[...]"

      But families are told to return to homes exposed to radiation levels that are comparable to those inside a nuclear plant…

      "While 1 mSv a year remains the government’s long-term target, it is encouraging people to return to areas where radiation levels are below 20 mSv a year, an annual exposure limit that, internationally, applies to nuclear power plant workers."

      Safely contained… wishful thinking

    It's been a long time since I tried to get any info about the supposed attempt to use monkeys at Fukushima to measure radiation in the forests of Fukushima. One example of this story for anyone unfamiliar with this:

    The last time I did any looking about, I found that they were using pigs and the article I found was only going into how they were testing equipment and no information on actual radiation reading were given.

    If you feel like having a go at finding any actual success, I bet you meet a dead end.

    I suspect someone realized that animal rights activists might complain about subjecting monkees to radiation and might suggest that they be evacuated. Remember, most "decontamination" only extended 20 feet from roads. Have you ever went on a hike? With a large heavy backpack, 20 feet might seem like alot, but I have done this and (scientists might be perplexed and bewildered) found that forests are generally deeper than that.

    This monkey powered radiation project was announced way back in 2011 in major media but the short attention span idiocracy fails to demand answer

    The next "Planet of the Apes" movie could have Caesar meeting up with Fukushima apes. Caesar could take a Geiger counter reading and get all the apes to storm corporate offices. When Caesar realizes that humans don't know the difference between a banana and a fuel rod, he realizes that humans are too stupid to rule the planet.

    Activists Sue to Block Plans to Bury 3.6 Million Pounds of Nuclear Waste Near California Beach

    Environmental activists in California are fighting plans to store 3.6 million pounds of highly radioactive nuclear waste on a popular beach in San Diego County. In 2012, a radioactive leak at the San Onofre nuclear power plant forced an emergency shutdown. The plant was fully closed by June 2013. Now residents are fighting the permit issued by the California Coastal Commission to store the millions of pounds of nuclear waste in thin, stainless steel canisters, within 100 feet of the ocean. We speak to Ray Lutz, founder of Citizens’ Oversight, which has filed a lawsuit challenging the expansion of the nuclear waste storage facility.

    [ short vid segment and transcript at the link, good exposure for Citizens' Oversight. ]

    RAY LUTZ: This is the biggest human blunder of all time. These nuclear plants are uneconomic. They should be all shut down. We’ve got to really push hard to get this industry to stop.

    "This report is being made pursuant to 10 CFR 50.72(b)(3)(v)(D) for an event or condition that could have prevented fulfillment of a safety function needed to mitigate the consequences of an accident.

    The Low Pressure Core Spray (LPCS) Pump Injection HI Flow alarm was received at 09:08 CDT on May 17, 2017, at which point the minimum flow valve was observed to go closed.

    The LPCS pump remained in standby during the event.

    To prevent damage if the pump were to auto start, the control switch for the LPCS pump was placed in pull to lock.

    This condition prevents LPCS, a single train safety system, from performing its design function.

    This is a reportable condition as an 8 hour ENS notification.

    "The required action of Technical Specifications (TS) 3.5.1, 'ECCS – Operating,' was entered on May 17, 2017 at 09:08 CDT when the condition was identified and the LPCS system was determined to be inoperable.

    Investigation into the cause of the condition is in progress.

    There were no related work activities in progress at the time the condition was identified."

    At the end of this video, it says that if you work at Chernobyl nuclear plant for a year, you will receive about the equivalent dose of a chest X-ray.

    They built that giant metal cover with international cooperation and 2.3 billion dollars

    to confine a chest x-ray. ????????????????????????????????????????????
