    Pennsylvania watershed contaminated with radioactive material and endocrine-disrupting chemicals https://watchers.news/2017/07/12/pennsylvania-watershed-contaminated-with-radioactive-material-and-endocrine-disrupting-chemicals/

    Posted by TW on July 12, 2017

    Hydraulic fracturing has enabled a domestic oil and gas boom in the U.S., but its rapid growth has raised questions about what to do with the billions of gallons of wastewater that result. Researchers now report that treating the wastewater and releasing it into surface waters has led to the contamination of a Pennsylvania watershed with radioactive material and endocrine-disrupting chemicals. The study appears in ACS' journal Environmental Science & Technology.

    Trump Sparks Fight Over Nuclear Mountain
    Jul 12, 2017

    “…But this will not eliminate the federal government's role with respect to nuclear waste. No privately chartered agency can be expected have the wherewithal to take on liabilities of this magnitude–or guarantee safety in increments of geologic time. The EPA's regulations in this regard speak in terms of 10,000 years. Some of the waste, however, will remain radioactive for 100,000 years and not even governments last that long. The Macfarlane-Ewing proposals, if enacted, might go a long way in deal-ing with the current state of nuclear storage but do they go far enough to diffuse the energies of anti-nuclear activists? Probably not….”

    "On July 12, 2017, at 1238 Eastern Daylight Time (EDT), Watts Bar Nuclear Plant (WBN) determined that a preliminary analysis shows adequate Essential Raw Cooling Water (ERCW) flow may not be in place during dual unit limiting design basis conditions of one unit in Hot Shutdown on Residual Heat Removal (RHR) cooling when the other unit experiences a Loss of Coolant Accident (LOCA).

    Based on preliminary analysis, during a Unit 1 LOCA, Unit 1 receives adequate flow when following existing procedural guidance; however, Unit 2 may not receive adequate flow to meet cool-down requirements with design basis maximum temperatures.

    During a Unit 2 LOCA, however, current procedural guidance is not adequate to ensure the proper system alignment to establish correct ERCW Component Cooling Water (CCS) Heat Exchanger A and B flow rates for either unit's cool down requirements.

    "Unit 2 has been shutdown for an extended period of time such that the flow delivered by ERCW is adequate to serve both Unit 1 in a LOCA and Unit 2 in less than Mode 3.

    PART 21 – DEFECTIVE SAFETY RELATED VALVES https://www.nrc.gov/reading-rm/doc-collections/event-status/event/2017/20170714en.html#en52857

    "The stem for the Subject valve models was identified as being undersized based on allowable yield stress analysis of the stem while in torsion.

    The high stress condition was due to the high torque required to seat/unseat the plug when installed with a Ultra High Molecular Weight Polyethylene (UHMWPE) sleeve material.

    High friction factor inherent with this material causes torsional stress to exceed the upper limit of yield strength of the valve which could result in fatigue/yielding of the stem, thus preventing the valve from opening and closing while in service.

    Historical research performed thus far has not identified any notifications from the customer(s) regarding stem failure of the subject valves, indicating that the valves may still be in operation with no performance related or operating issues.

    "Notifications letters have been sent to the affected plants advising them of the condition, and recommending that the sleeve material be replaced with a lower friction Polytetrafluomethylene (PTFE) material that would significantly reduce the required input operating torque, thereby reducing the risk of failure of the stem material.

    The following facilities received these safety related orders: TVA Sequoyah, Pennsylvania Power & Light Susquehanna.

    “RGPu [Reactor Grade Plutonium] can be used in weapons. Moreover, the links between nuclear power (and civil nuclear programs more generally) and weapons proliferation go well beyond the use of RGPu in weapons. Ostensibly civil nuclear materials and facilities can be used in support of weapons programs in many ways:

    “Production of plutonium in power or research reactors followed by separation of plutonium from irradiated material in reprocessing facilities (or smaller facilities, sometimes called hot cells).

    “Production of radionuclides other than plutonium for use in weapons, e.g. tritium, which is used to initiate or boost nuclear weapons.

    “Diversion of fresh highly enriched uranium (HEU) research reactor fuel or extraction of HEU from spent fuel.

    “Nuclear weapons-related research.

    “Development of expertise for parallel or later use in a weapons program.

    “Nuclear power programs justifying the acquisition of other facilities capable of being used in support of a nuclear weapons program, such as enrichment or reprocessing facilities.

    “A nuclear power reactor (1000 MWe LWR) typically produces 250−300 kilograms of plutonium each year, sufficient for 25−30 weapons. Total global production of plutonium in power reactors is about 70 tonnes per year. Over 2,000 tonnes of plutonium have been produced in power reactors around the world, hence the importance of the debate over the use of RGPu in weapons….”

    Money runs short for nuclear energy’s survival http://climatenewsnetwork.net/nuclear-runs-out-of-money-and-steam/

    June 24, 2017, by Paul Brown

    Renewable fuels are challenging nuclear energy’s survival everywhere, and financing new reactors is growing increasingly difficult.

    LONDON, 24 June, 2017 – Anywhere you look in the world, the future of the nuclear industry looks grim as costs escalate and politicians plump for renewables, putting nuclear energy’s survival in doubt.

    The single most important fact in the industry’s demise is that its main rivals in the business of generating electricity – gas, wind and solar – are getting ever cheaper as nuclear costs only rise.

    The political tide is turning against nuclear power in previously leading countries. Newly elected governments in South Korea and France, the two democratic countries most enthusiastic about the atom, are looking to reduce the role of nuclear in their energy mix.

    A report by Bloomberg, the financial reporting service, says that more than half the US reactors currently in operation are losing money, and most of the rest are struggling to break even.

    Exelon's Nine Mile Point-2 in New York at reduced power for repairs https://www.platts.com/latest-news/electric-power/washington/exelons-nine-mile-point-2-in-new-york-at-reduced-21334731

    Washington (Platts)–14 Jul 2017 454 pm EDT/2054 GMT

    Power at Exelon Generation's 1,362-MW Nine Mile Point-2 nuclear reactor in Scriba, New York, was reduced late Thursday from 100% of capacity "due to an air leak in an instrumentation line," plant spokeswoman Jill Lyon said in an email Friday.

    The unit was operating at 52% early Friday, according to the US Nuclear Regulatory Commission's daily reactor status report.

    Citing "competitive reasons," Lyon declined to estimate the duration of the repair work being done on the line, or when the unit would return to 100% power.

    "Troubleshooting has preliminarily identified the cause as an instrument air leak stemming from a 2-inch line failure that caused condensate booster pump valves to unexpectedly open," Sheehan said.

    Ka-boom — Saturday explosion to topple Hanford vent stack http://www.tri-cityherald.com/news/local/hanford/article161534033.html

    The 200-foot-tall ventilation stack at Hanford’s Plutonium Finishing Plant is scheduled to crash to the ground Saturday after explosives are detonated.

    It’s the next step toward getting the high-risk plant at the nuclear reservation torn down to the ground by the end of September.

    DOE officials have called it the most hazardous demolition project at the nuclear reservation.

    Workers have spent several weeks preparing for the stack to come down.

    Today was supposed to be the day they dropped the Hanford stack, wonder how it went.

    Nothing on the Hanford twitter feed about it. Just the rah, rah from the other day day about how safe they are.

      https://www.nrc.gov/reading-rm/doc-collections/event-status/event/2017/20170717en.html#en52859

      "This telephone notification, […] to describe an unplanned, invalid actuation of containment isolation valves in more than one system which occurred during the most recent refueling outage at Fermi 2. On 3/24/2017, at approximately 1548 EDT, when synchronizing an emergency diesel generator (EDG) to the grid during testing, an electrical perturbation occurred.

      Further investigation found that the EDG was slightly out of phase when it was attempted to be synchronized to the grid.

      The electrical perturbation resulted in an unexpected half-scram of Reactor Protection System (RPS) A and actuation (closure) of some containment isolation valves.

      The actuations were invalid as they were not initiated in response to actual plant conditions or parameters satisfying the requirements for initiation.

      Fermi 2 was shut down for a refueling outage at the time, and therefore, the half-scram of RPS A occurred after the safety function had already been completed.

      Containment isolation valves actuated (closed) in Division 1 of the Torus Water Management, Drywell Pneumatics, and Drywell Floor and Equipment Drain Sumps systems.

      All valves operated as expected.

    During a rain and lightning storm, plant operators observed arcing from the main transformer bus duct and notified the control room.

    The decision was made to trip the main generator which resulted in an automatic reactor trip.

    The plant entered EAL SU.1 as a result of the loss of offsite power for greater than fifteen minutes.

    Plant safety busses are being supplied by both emergency diesel generators while the licensee inspects the electrical system to determine any damage prior to bringing offsite power back into the facility.

    Offsite power is available to the facility.

    No offsite assistance was requested by the licensee.

    During the trip, all rods inserted into the core.

    Decay heat is being removed via the atmospheric dump valves with emergency feedwater supplying the steam generators.

    The main steam isolation valves were manually closed to protect the main condenser.

    There were no safeties or relief valves that actuated during the plant transient.

    Areva plant in Richland to make nuclear fuel that’s better in emergencies http://www.tri-cityherald.com/news/local/hanford/article161889383.html

    acary@tricityherald.com

    The Areva plant in Richland will begin manufacturing newly developed advanced nuclear fuel assemblies that allow operators more time to respond in emergencies.

    The plant will start manufacturing the fuel later this year, to be loaded into one of the units at Georgia’s Vogtle Electric Generating Plant in the spring of 2019.

    Congress provided funding to develop fuels that can tolerate loss of active in cooling in the reactor core for much longer while maintaining of improving fuel perfomance during normal operations.

    The fuel pellets to be manufactured in Richland will have chromia additions, providing a higher density and helping reduce fission gases if a reactor loses cooling. Chromium coating also will be added to fuel rod cladding.

    [ wonder how the addition of chromium will add to the toxicity of spent fuel
    or what will this create in event of a melt. ]

    MATSUYAMA, Japan (Kyodo) — A court on Friday rejected residents' plea to halt a reactor operating at the Ikata nuclear power plant in western Japan amid concerns about the robustness of an evacuation plan in the event of an accident.

    The Matsuyama District Court ruled against the residents' request to stop Shikoku Electric Power Co.'s No. 3 reactor at the plant in Ehime Prefecture. In March, the Hiroshima District Court also rejected calls for an injunction ordering the reactor to be halted.

    The focal points of Friday's decision were the feasibility of the evacuation plan, the effectiveness of new safety standards introduced after the 2011 Fukushima nuclear crisis, and the likelihood of potential quakes assumed by the utility in designing the reactor's seismic resistance.

    Amory Lovins: Nukes Not the Answer https://www.ecowatch.com/nuclear-climate-change-2462663343.html

    Lovins's analysis contrasts sharply with Secretary of Energy Rick Perry's asser­tions that nation­al security requires favoring coal and nuclear plants. Lovins shows that all 14 "magical proper­ties" claimed to merit paying more for such plants (or even mandating them) are imaginary, including "large-scale" generation, dispatchability, loadshape value, having "fuel on hand," price deflation, volatile fuel prices, jobs and supporting America's nuclear weapons capability. Lovins espe­cially debunks national-security and grid-reliability claims by showing that coal and nuclear plants actually have unique and serious vulnerabilities (as his authoritative Pentagon analysis Brittle Power: Energy Strategy for National Security first explained in 1981).

    Chicago park will finally be cleansed of radioactive waste https://archpaper.com/2017/07/chicago-park-radioactive-waste/

    By Matthew Messner (@MessnerMatthew) July 20, 2017

    The radioactive element, once heavily used in the making of gas light mantels, can now be found in contaminated superfund sites across the city. One of those sites also happens to be the long-delayed and much-anticipated DuSable Park in the downtown Streeterville neighborhood.

    Thorium, a naturally occurring radioactive element, is notoriously hard to clean up, in part because of how it gets into the soil in the first place. As with many other sites around Streeterville, DuSable Park’s thorium is likely from the Lindsay Light Company, which processed the material from raw ore and manufactured gas light mantles in the area from 1904 through 1936. Some of the waste from the refining process is a sand-like material called thorium mill tailings, which was often used as infill in the low-lying Streeterville. It is likely thorium mill tailings were used as part of the fill on the DuSable site, which is reclaimed land from the lake. A second costly factor in removing thorium is that is can only be trucked to a few disposal sites in the United States. The only one that is likely to take the waste from DuSable is in Utah.

    Michel Arakino

    “From 1981 to 1996 I was a diver at Moruroa. My work consisted of taking biological samples from around the zones and in the zones where the detonations had occurred.

    At the first meeting of Moruroa e tatou[1], I came just to listen and tell my bosses what they were saying,
    [ basically he was sent there too spy on the activists ]
    but then I was especially struck by Dr. Sue Roff. I was sitting in the front row watching this woman explain the effects of radioactivity. Everything she said concerned me directly.

    I was the positive control organism in this experiment, and that’s when I realized what I was passing down to my children.

    That’s when I started asking questions to the authorities, and they quickly became hostile. What should I say? It was like we were no longer friends. The relationship was tarnished because I was asking too many questions about the state of my health.”

        He recalls: "The bosses said: ‘It’s OK, you can go over there.’ We were scared, but if we’d refused, we would have been on the next plane back to Tahiti the following day. We would have lost our job, so we went ahead cleaning up without asking any questions."

        In 1980, Raymond’s daughter Cinya was born, the only girl of five children. She died a year later, from complications with a malformed lung. In 1994, he was diagnosed with leukaemia and sent on a stretcher to a hospital in Paris, where he underwent two years of chemotherapy.

The Reactor Pressure Vessel was flooded up during the refueling outage, thus, the actuations of the HPCS pump and its supporting emergency diesel (DG3) were unplanned and invalid. The HPCS pump did not inject into the RPV due to the RPV level being above Level 8 which is an interlock to close the HPCS RPV injection valve (HPCS-V-4).

    Santee Cooper and SCANA (45% and 55% owners respectively) cite the fact that electric rates have ALREADY been raised 5 times to cover costs.

    Toshiba pledged $2.2b to finish the project leaving a $9.2b GAAP gap, which SC and SCANA have no confidence to invest in. It seems no-one wants to build a nuclear station unless they use someone elses money to build it, insure it, clean up it's mess ( that someone else is you btw ).

    These were AP1000 designs that Wastinghouze thought looked good on napkins but had to be fixed as they actually built it.

    The builders had an Aug 10 deadline to file a cost analysis that they must not be able to make. There was also a 2021 deadline to qualify for tax credits that they project they will miss.

    Voglte in GA is in the same mess with a decision on continuing due later in August but these units are closer to completion.

    Ratepayer and taxpayers ( you again ) will be paying for this scam for a long time while all the investors and execs live in luxury.
