    [ long EN – synopsis – appears they filled a UF6 cylinder using the wrong procedure. The procedure NOT used prohibits an inadvertent criticality. Luckily no adverse event occurred. ]


    "11/2/2017 1429 MST Update: Based on existing liquid sample results, conservatively assuming a moderator concentration of 0.5 percent, the filled cylinder's heel meets the acceptance criteria. This demonstrates a criticality event to be highly unlikely and therefore, the anomalous condition was exited at 1242 MST."

    [ Events like this are another major reason why the nuke industry s/b shutdown. The people involved are supposedly highly trained, are highly paid, and yet continually seem to be unable to follow their own processes to ensure safety. This kind of nonchalant behavior is prevalent throughout the industry. I have contacted the intergalactic stock market and have shorted the Earth. I'll be the richest dead man from Earth. ]

    (2004)"Radioisotopes are introduced into the environment following nuclear power plant accidents or nuclear weapons tests. The immobility of these radioactive elements in uppermost soil layers represents a problem for human health, since they can easily be incorporated in the food chain. Preventing their assimilation by plants may be a first step towards the total recovery of contaminated areas…
    Release of radionuclides to the environment represents a risk to human and animal health both as a source of irradiation and, above all, for the toxicity exerted at the cellular level by mutagenic, teratogenic and oncogenic actions [1,2], because of their presence in the food chain ..
    Contaminated soils treated with an acid solution of ions NO3-, PO4— and K+, undergo a reduction of radioactivity up to 35%, after a series of washes which simulate one year's rainfall. The capacity of the deepest soil layers to immobilize the radionuclides percolated from the superficial layers was also confirmed."

    Contractor wasted millions on unnecessary supplies for S.C.'s failed nuclear reactors

    “COLUMBIA — Westinghouse Electric squandered millions of dollars on unnecessary supplies in its failed attempt to build two nuclear reactors in South Carolina, including tens of thousands of hand-machined nuts that cost $114 apiece when a sturdier $2 alternative was available, a Post and Courier investigation found.

    “Internal cost analyses and interviews with four engineers who worked on the project highlight how poorly vetted designs, questionable purchasing decisions and improperly stored materials contributed to millions of dollars in needless spending by Westinghouse, the project's primary contractor. …”

    California’s last nuclear power plant — Diablo Canyon — may be one step closer to closing, despite a vocal campaign to save it.

    The California Public Utilities Commission on Wednesday issued a proposed decision that would approve plans by Diablo Canyon’s owner, Pacific Gas and Electric Co., to shut it down when the plant’s operating licenses expire, in 2024 and 2025.

    A majority of the commission’s five voting members must approve the plan for it to take effect. A vote could come as early as Dec. 14.

    The proposed decision issued Wednesday would largely approve PG&E’s plan, but with a few changes.

    US FERC chairman seeks to advance interim step to extend lifeline to baseload

    Washington (Platts)–9 Nov 2017 151 pm EST/1851 GMT

    US Federal Energy Regulatory Commission Chairman Neil Chatterjee said he hopes to forge ahead in the coming weeks an interim step that extends a lifeline to coal and nuclear plants that are at risk of premature retirement.

    [ premature retirement ? , the units that had their 20yr design lifespans extended another 20 yrs. ]

    Speaking Thursday at a Platts Energy Podium event, Chatterjee said he sees no need to stave off action on the Department of Energy's contentious energy market proposal on pricing resilience and reliability until two newly confirmed commissioners, one of whom will ascend to the chairmanship, are sworn in.

    In September, DOE issued a notice of proposed rulemaking to FERC seeking new market rules that would provide full cost recovery and a return on investment to generators with 90-day on-site fuel supplies.

    [ full cost recovery and ROI means all operating costs plus a profit, that's not free market. ]

    Chatterjee told reporters he would like to see an interim solution linked, using a sunset provision, to a longer-term analysis that solves broader concerns over grid resilience and baseload generation.

    Fukushima's forgotten radionuclides: a review of the understudied radioactive emissions.

    In environmental monitoring campaigns for anthropogenic radionuclides released in the course of the Fukushima nuclear accident (2011), most focus had been on gamma-emitting radionuclides. More than 99% of the released activity was due to radionuclides of the elements Kr, Te, I, Xe, and Cs. However, little work had been done on the monitoring of radionuclides other than (131)I, (132)Te, (134)Cs, (136)Cs, and (137)Cs. Radionuclides such as those of less volatile elements (e.g., (89)Sr, (90)Sr, (103)Ru, (106)Ru, plutonium), pure beta-emitters ((3)H, (14)C, (35)S), gaseous radionuclides ((85)Kr, (133)Xe, (135)Xe) or radionuclides with very long half-lives (e.g., (36)Cl, (99)Tc, (129)I, some actinides such as (236)U) have been understudied by comparison.

    “The Capitalist Tool” Just Trolled Trump Over Coal & Nuclear Energy
    November 12th, 2017

    “If President* Donald Trump thought he could count on the Forbes media empire to help protect coal and nuclear power plants, well, he was wrong. In yet another sign that nobody likes coal, on Sunday, the self-described 'home page for the world’s business leaders' published a long contributor piece featuring an interview with the lead technical author of the Energy Department’s notorious grid study, and she does not mince words.

    “For those of you keeping score at home, a contributor is not the same as a staff writer, and the Forbes piece comes with a disclaimer that ‘opinions expressed by Forbes Contributors are their own.’ Still, it’s significant that the news organization formerly known as The Capitalist Tool would lend its media platform to an authoritative takedown of Trump’s energy policy.

    “What New Grid Study?

    “For those of you new to the topic, last spring, Energy Secretary Rick Perry ordered a new grid study with the apparent aim of justifying new protections for large “baseload” power plants, primarily coal and nuclear.

    “A leaked memo ordering the study touched off a firestorm of pushback, even among fossil fuel stakeholders, and a leaked draft of the study found no basis for special protections.

    • Dr. Anne Lee Tomlinson Maziar Dr. Anne Lee Tomlinson Maziar

      “Nevertheless, last month, Perry asked FERC to approve a new rate structure that would enable outdated coal and nuclear power plants to continue operating — at a profit, no less — even if more economical alternatives are available.

      “With the new contributor piece, Forbes has pushed a not-so-subtle argument against the new protections to FERC in advance of its final ruling, which is expected by December 11.

      “So, What’s Wrong With The New Grid Study?

      “The Forbes piece was written by longtime environmental reporter Jeff McMahon under the title, ‘Author Of DOE Grid Reliability Study Describes Being Pressured To Fault Regulations.’

      “The lead technical author, Alison Silverstein, is an energy consultant with a background in renewables. According to multiple reports, she was personally selected by Secretary Perry, who also has a strong background in renewables (in Texas). That alone should have raised some red flags among coal fans.

      “Do read the McMahon piece for full effect. For those of you on the go, it boils down to one basic point of contention: the Trump administration wanted to fault over-regulation — namely, the 2015 Clean Power Plan — for causing a rash of coal and nuclear power plant closures.

      “Silverstein did not find any such evidence in the data. The data indicate that a cluster of closures in the runup to the 2015 deadline involved plants that were already “failing economically.” They would have closed sooner or later, Clean Power Plan or…

      • Dr. Anne Lee Tomlinson Maziar Dr. Anne Lee Tomlinson Maziar


        “In Silverstein’s view, the cluster occurred because the deadline gave some plant operators an excuse to keep operating a little longer than they would have:

        “’That regulation date, the compliance deadline, is the edge of the cliff, and I’m just going to gun it and run this flat-out as fast as I can and get every possible kilowatt hour out of it before I have to shut it down—Boom!—and go out in a blaze of glory, literally. So that’s why you saw all those retirements at that deadline. It’s just common sense operational strategy not to piss away money.”’

        “As for why the plants were closing, Silverstein agrees with the consensus view among energy stakeholders: cheap natural gas has been the main driver behind coal plant closures.

        “For that matter, the Clean Power Plan was challenged in court by 'friends of fossil fuels' and never went into effect, but the coal plants keep shutting down, one after another.

        “Another Twist Of The Knife For Coal

        “Silverstein has a way with words, and in parts of the interview she seems to speak directly to FERC:

        “’The most important thing: the coal and nuclear plants that retired were old, really old, and really inefficient, and they had earned their AARP cards, and it was time for them to get off the playing field and go enjoy a nice retirement somewhere. A whole lot of these plants retired well before renewables got big.’ [cont.]

        • Dr. Anne Lee Tomlinson Maziar Dr. Anne Lee Tomlinson Maziar

          “Silverstein also has a message for businesses that depend on grid-supplied electricity, which is virtually all of them:

          “’They cannot provide the essential resiliency and reliability services that we need, like voltage support, reg-up, reg-down, primary frequency response, secondary frequency response. Coal and nuclear plants are just not good at anything but spinning reserve.’

          “That message could also be aimed at the Department of Defense, which has been steadily disentangling itself from the coal and nuclear baseload model.

          “You can get a more detailed takedown of the final recommendations from Silverstein herself at Utility Dive, under the title, “If I’d Written the DOE Grid Study Recommendations.”
          What Now, FERC?

          “Although Silverstein’s technical work went largely unchanged, the final version of the grid study includes a set of recommendations that supports Perry’s FERC proposal.

          “Silverstein stands by her work but she strongly disavows any connection to the grid study recommendations, which were written after she finished her part of the assignment and returned home.

          “Perry already appears to be distancing himself from culpability if the protections go through. Rather than going the normal procedural route, Perry exercised the Energy Department’s authority to place items on the FERC agenda. [cont.]

    Russia says to help PH build nuclear power infrastructure
    Posted at Nov 14 2017

    “MANILA – Russia's state nuclear corporation, Rosatom, said Tuesday it would help the Philippines develop a nuclear power infrastructure under a memorandum of agreement with the Department of Energy.

    “The 2 parties also agreed to "explore the possibilities" for the construction of land-based or floating nuclear power plants with small reactors, Rosatom said in a statement.

    “The Bataan Nuclear Power Plant will also be assessed to determine its possible reopening, according to the statement…“

    TEPCO’s Magic Truck
    November 10, 2017

    “TEPCO recently presented a pump truck concept to Japan’s nuclear regulator (NRA). The company is trying to use this concept as part of the case being made to allow them to restart the massive nuclear power plant, Kashiwazaki Kariwa.

    “TEPCO had previously installed filtered vent systems for the unit 6 & 7 reactors at Kashiwazaki Kariwa as part of this restart upgrade process. The ability of these vent filters to solve all problems in the event of a severe accident has been criticized as not being totally foolproof. Vent filters are better than no vent filters as it does offer another line of needed defense. They will not solve all the risks of a severe accident.

    “Now TEPCO rolls out their pump truck concept but this seems even more questionable than the filtered vent system as a safety response…”

    The first measurements made of artificial radionuclides released into the marine environment did reveal that radionuclides are concentrated by marine biological species. The need to report radionuclide accumulation in biota in different conditions and geographical areas prompted the use of concentration factors as a convenient way to describe the accumulation of radionuclides in biota relative to radionuclide concentrations in seawater. Later, concentration factors became a tool in modelling radionuclide distribution and transfer in aquatic environments and to predicting radioactivity in organisms. Many environmental parameters can modify the biokinetics of accumulation and elimination of radionuclides in marine biota, but concentration factors remained a convenient way to describe concentration processes of radioactive and stable isotopes in aquatic organisms. Revision of CF values is periodically undertaken by international organizations, such as the International Atomic Energy Agency (IAEA), to make updated information available to the international community. A brief commented review of radionuclide concentration processes and concentration factors in marine organisms is presented for key groups of radionuclides such as fission products, activation products, transuranium elements, and naturally-occurring radionuclides.

    Manufacturers are increasingly using encapsulated coal ash from power plants as a low-cost binding agent in concrete, wallboard, bricks, roofing and other building materials. But a new study by U.S. and Chinese scientists cautions that coal ash from high-uranium deposits in China may be too radioactive for this use.

    The level of radiation in this coal ash could pose human health risks, particularly if it is recycled for use in residential building materials, he said.

    Some of the coal ash samples analyzed in the new study contained radiation levels more than 43 times higher than the maximum safe limit established for residential building materials by the United Nations Scientific Committee on the Effects of Atomic Radiation.

      This is a LOT of speculation, including some poor recall but mostly from crap I read and try to describe as mentioned.

      PAH, buckyballs (I forgot who mentioned that, sorry, but that was an interesting mention)?

      Then, if you recall the article about PAH at the PNNL site finding "confusing" levels of PAHs recently, suggesting it came from across the pacific…it's, something.

      Maybe look at the differences between coal, coal ash and wood ash, too. The coal typically has even more PAHs than the coal ash.

      From my understanding, much of that is then released when it (coal, wood, etc) is burned (some things may concentrate), however the type of coal or wood (like say, being contaminated, or just mostly naturally adsorbed) would have varying levels of radioactive materials associated with it.

      Another interesting thing is, they're associating other pathogens with that too (mutagenic, roughly but I think they said something about it being protective for some organisms, basically).

      Now, I dunno about how much of that is true, or trying to deflect…but.

      This suggests not many PAHs from an NPP seems to have locally, terrestrially found with respect to nuclear:

      But then I wonder about that PNNL article, and the stunning lack of info correlating PAHs with nuclear emissions, explosions, or burning of say, radioactive trees or coals, minerals or waste.

      • FaunaLord Farthington MacMananus

        There was I think one article I linked to, I dunno, 6 months ago? I think it was about the only one I could find, I think it was about high levels of PAH at a Georgia nuke waste site. That's like, the best I could find and it wasn't easy getting to that.

        • FaunaLord Farthington MacMananus

          So again.

          "PAHs typically disperse from urban and suburban non-point sources through road run-off, sewage, and atmospheric circulation and subsequent deposition of particulate air pollution.[26] Soil and river sediment near industrial sites such as creosote manufacturing facilities can be highly contaminated with PAHs.[10] Oil spills, creosote, coal mining dust, and other fossil fuel sources can also distribute PAHs in the environment.[10][27]"

          That's convenient, wouldn't you say (I mean, just look at the extent of PAH production, yet no mention of nuclear)?

          As if the nuclear industry doesn't rely on much of that, at the very least.

    At 1118 CST on 11/14/17, Cooper Nuclear Generating Station declared an Unusual Event due to a hydrogen leak on a main generator purge line.

    The leak was reported to be caused by Maintenance cutting into a one inch line.

    The total size of the leak is unknown, however, it is estimated to be depressurizing in the main generator at approximately 1lb per hour.

    The current pressure is 52 to 53 lbs. pressure and is stable.

    The operations staff have entered their abnormal procedure and are taking actions to isolate the leak.

    Operators have isolated the source of hydrogen and have opened the exterior roll up doors to increase the airflow and minimize the concentration of hydrogen in the area.

    The area has been evacuated and hot work has been stopped.

      The U.S. Department of Energy (DOE) has decided to resume a program of transient testing,[4][5][6][7][8] and plans to invest about $75 million to restart the TREAT facility by 2018. The renewed interest in TREAT was sparked by the 2011 Fukushima Daiichi nuclear disaster, which prompted the shutdown of Japan's and Germany's nuclear plants. One use for TREAT is planned to be testing of new accident tolerant fuel for nuclear reactors.[9][10][11]

    Wow, Jebus. The TREAT facility is "testing of new accident tolerant fuel for nuclear reactors." Accident tolerant fuel?!? Sounds like 'Peak Stupidity' is a few years off, yet.

    A Nuclear Jet at Chernobyl Around 21:23:45 UTC on April 25, 1986

    The nature of two explosions that were witnessed within 3 s at the Chernobyl-4 reactor less than a minute after 21:23:00 UTC on April 25, 1986, have since then been the subject of sprawling interpretations. This paper renders the following hypothesis. The first explosion consisted of thermal neutron mediated nuclear explosions in one or rather a few fuel channels, which caused a jet of debris that reached an altitude of some 2500 to 3000 m. The second explosion would then have been the steam explosion most experts believe was the first one. The solid support for this new scenario rests on two pillars and three pieces of corroborating evidence. The first pillar is that a group at the V. G. Khlopin Radium Institute in then Leningrad on April 29, 1986, detected newly produced, or fresh, xenon fission products at Cherepovets, 370 km north of Moscow and far away from the major track of Chernobyl debris ejected by the steam explosion and subsequent fires.
