      "On January 26, 2018, a containment entry was made to identify the source of elevated Unidentified Reactor Coolant System (RCS) operational leakage.

      A through-wall leak was identified on a Class 1 piping weld on the letdown line at 0853 EST.

      It was determined that the leak was RCS pressure boundary leakage.

      Ginna entered Technical Specification (TS) LCO [Limiting Condition for Operation] 3.4.13, RCS Operational Leakage, Condition B. for the existence of pressure boundary leakage.

      This condition requires the plant to be in MODE 3 within 6 hours and MODE 5 within 36 hours.

      The leak was isolated and TS LCO 3.4.13 exited at 1015 EST.

      "This event is reportable within 8 hours in accordance with 10CFR50.72(b)(3)(ii)(A) for 'Any event or condition that results in: (A) The condition of the nuclear power plant, including its principal safety barriers, being seriously degraded'.

      "The Station [Ginna] is developing an evaluation and a repair plan at this time.

      "This condition has no impact on public health and safety.

      "The licensee has informed the NRC Resident Inspector."

      "Reactor SCRAM ONEP, Turbine Trip ONEP, and EP-2 were entered.

      Reactor water level was stabilized at 36 inches narrow range on startup level and reactor pressure stabilized at 933 psig using main turbine bypass valves.

        I just drain the thing into a pan and manually drain it. My water has no radionuclides in it (I hope). Can I get in trouble for that? I mean no radioactive death juice so it can't be clean and green right?

      "At 1310 hours [CST] on January 31, 2018, the Unit 2B fuel pool radiation monitor spiked high due to an invalid actuation which caused the U1 and U2 reactor building ventilation system to isolate, B train standby gas treatment system (SBGTS) started, and the control room ventilation system also isolated as designed.

      Secondary containment vacuum was lost for approximately one minute, and then subsequently returned to an acceptable level in accordance with Technical Specification, 'Secondary Containment.'

      As a result of this transient, secondary containment was inoperable for approximately one minute.

      No emergency conditions were determined to exist.

      Troubleshooting of the radiation monitor spike is underway.

      [ So this is confusing, I read the first paragraph as the rad mon spiked because the isolation trapped rad gas in the SFP area,causing the spike, yet the last sentence implies the rad mon spike may be the cause of the isolation. }

      ( Also note it started in " Unit 2B fuel pool ", unit 2 is scheduled for RFO in April, so they may have been moving SF around and caused the rad mon spike. ]

    UPDATE 1-EDF's Flamanville nuclear reactor startup schedule is tight -ASN

    • AirSepTech AirSepTech

      3 Min Read, if you please

      "EDF said in October it planned to load fuel in the long-delayed Flamanville European Pressurized Reactor (EPR) by the end of the fourth quarter of 2018, and aims for it to be fully up and running in late 2019.

      At the end of 2016, the ASN had ordered EDF to close 12 reactors following the discovery of excessive carbon concentrations in the steel of their steam generators, which makes the components more brittle. The ASN authorised their restart in March 2017.

      Chevet said that the financial restructuring of the French nuclear industry was also positive for nuclear safety.

      After years of losses wiped out the equity of nuclear group Areva, the firm was split up and recapitalised by the French state in an operation that was finalised late last year.

      Areva’s nuclear reactor unit has been sold to EDF while its nuclear fuel and uranium mining activities have been split off into a separate unit and rebranded Orano.

      The ASN wants EDF to upgrade safety at each of the reactors, including studying the possibility of adding a core catcher, a giant ashtray-like concrete bowl below the reactor that can contain the nuclear fuel in case of a meltdown."…more…

      "For example, potassium 40 (K40) is a typical natural radioactive nuclide. According to the Japanese government, the average internal exposure dose for adults from K40 is about 4,000Bq/year or 0.17mSv/year. See the website below (in Japanese).

      The ICRP risk model (2007) allows us to estimate the approximate risk posed by K40. The calculation shows that K40 is responsible for approximately 4,000 cancer cases and 1,000 deaths every year. If the same amount of radiation was added to that of K40 in the human body by artificial sources, the cancers and mortalities would be doubled to 8,000 and 2,000 a year, respectively. Based on the ECRR (2010) model, which criticizes the ICRP risk model as a severe underestimate, these figures should be multiplied by 40, reaching 320,000 and 80,000, respectively.

      The extract you cite from the Fukushima government website is completely fake: "In Fukushima, the indoor radiation doses are now so reduced that no radioactive cesium can be found in the air. Therefore, no radioactive particles can invade the human body during respiration". Reports from civic radiation measurement stations refute this claim. For example, dust collecting paper packs of vacuum cleaners used in Iwaki City, Fukushima prefecture, are radiologically measured and 4,800-53,900Bq/kg radioactive cesium was detected in…

    @ CodeShutDown

    Hey – Hope you're well. (I'm hanging in there, some improvements )

    Question: If you have the time, could you make a little list linking to comment threads and/or research papers that touch on the mystery why radiation from K40 is a peculiar exception to dose harm. Anything hinting of it having to do with electrical signal functions inside cell metabolism, or the frequencies (?) of keV decay energies, and such, would be lovely.

    Reason for my asking is a hunch that there's dynamic similarities to levels at vastly different scale (atomic / molecular / immune/body / social dynamic / international geopolitical / archetypal / …) and how insights in one might have parallels at another. The behavior of the immune system in regards to cancer cells, or how communities tend to defend malignant narcissists, etc. seem to have an element of confusion re. interpreting anti-social behavior. ingested fallout seems to do something similar.

      Hello MVB, It will take a little time to assemble. The absolutely definitive research paper does not exist, so we can only infer and theorize. There is one paper that did a meta search of frequencies and found bands of healthy and unhealthy frequencies and their octaves, which seems to be what you are getting at.

      Some very high frequency oscillations natural to cell structures has been identified. DNA seems to have electromagnetic/photon resonance. Octave and heterodyne effects are a given in any resonant system.

      'Resonance signals can be quantified to identify the types of cancer cells with a certain degree of DNA methylation. These measurements reveal the existence of molecular resonance fingerprints of cancer DNAs in the terahertz region, which can be utilized for the early diagnosis of cancer cells at the molecular level.'

      But on a different subject, the specific activity or radiation/density ratio stands out. Very few atoms of fallout radionuclides constitutes a toxic dose. A micro- bioaccumulation of even 10 to 100 atoms is already a significant local hot spot of radiation. Even when not decaying, the body may be able to sense the foreign nature of isotope.

        Not only DNA but many cellular features are naturally vibratory and of course every molecular bond has resonance frequencies. A lab diagnostic technique uses frequency specific signatures of double bonds for example.
        On the whole, physical vibrations will be super damped because viscosity rules at small sizes. Resonance factors may not apply in a biological action. Standard mechanical/chemical views of biology are suitably explanatory and exclude electromagnetic and resonance effects.

        Busting the assumed equivalence of background radiation and nuclear fallout would be a huge step in overturning the established science which allows nuclear, legally and conceptually. Bioconcentration factors of certain amino acids, some fungal and microorganisms, cellular recognition of isotopes could all play a role. More obscure studies like biophotons and quantum cellular processes may come into play. The cell and body are informationally unified. Thats a long distance! Positron emission scans use gamma from antimatter annihilation as a diagnostic.

                Something else… mid-Dec, I sent a urine sample to a lab for gammaspectroscopy. Only K40 detected with 95% certainty, with 3 other ones failing to make the certainty cut (Ac-228, Ra-228 & Th-232. From local foods grown in this thorium-rich region? All ND, < MDA, with 95% cert. though)

                Interestingly, of the quality control samples [one is done 'blank' and the other one spiked (with Am-241, Cs-137 & Co-60)]: the blank one "identified" these (and of course this just being noise that baraly makes the cut, and falls well below MDA, so all considered Non-Detected, just interesting which one were at first 'identified':
                Sn-117M Te-123M
                BA-137M Cs-137
                Tl-208 Bi-214 Th-232 Th-234 U-238
                The only truly striking bit is this: all were '<MDA' (U , undetected), except Cs-137, which, due to a wide peak was deemed a false positive and tagged IU = Identification Uncertain. Funny "blank"…

                Anyhow… Will be hard to proof a covered-up fallout event, at least as far as it showing up in urine goes, if the reference point is 'uncertain' or spiked with the very isotopes that would show up in case of (bomb) fallout… Anyhow, thought it was worth the shot, but all-in-all, it didn't reveal anything. (Was just trying to figure out what made me so sick. Still in limbo as far as the hard sciences angle goes)

                MVB…this is the main thing; nature untouched by modern civilization is the foundation of natures quest for biological excellence. It included this radioactivity from the beginning. The healthiest animals that ever lived had it. No exclusion zones, no genomic instability, no bystander effect. Now Bandazhevsky showed the SAME level of radiation from cesium137 causes heart disease.

                Its a metabolic thing…a complex metabolic change of inflammation, micro messenger RNA, reactive oxygen species. Low level radiation from fallout is not about DNA hits, its about metabolic alteration. This much is known. Now why there is a difference in radiation quality…thats the cutting edge science…yet to be elucidated.

    Exelon debates value of Byron nuclear plant

    BYRON, Ill. (WIFR) – The Ogle County Board of Review makes a decision on the value of the Byron power plant after Exelon says the current value is too high.

    Exelon filed an appeal saying the value they were given by the assessor was too high; that value was $546 million, however, the board of review agreed to keep it at that amount.

    The school district was asking for the property value to be assessed at $647 million, however, Exelon asked for $158 million according to Ogle County Supervisor of Assessments James Harrison.

    "There's a lot of things to look at in these appraisals. One of the things that sort of bothers me is the inconsistency of the Exon appraisals over the years. They ask for this and then they ask for that. The school's appraiser seems to be a little more consistent," says Harrison.

    If Exelon chooses to, their next step will be to file with property tax appeal board.

    "At 1057 CST on February 1, 2018 with the unit in Mode 1 at approximately 27% power, a manual actuation of the Reactor Protection System (RPS) was initiated due to an unexpected trip of the B Recirc Pump with A Recirc Pump in fast speed.

    B Recirc Pump tripped during transfer from slow to fast speed resulting in single loop operation.

    Operators were unable to reconcile differing indications of core flow.

    This resulted in a conservative decision to initiate a manual scram.

    The cause of the B Recirc Pump trip and the apparent issues with core flow indication are under investigation.

    The plant is currently stable in Mode 3.

    "The plant response to the scram was as expected. All control rods [fully] inserted as expected; the feedwater system is maintaining reactor vessel water level in the normal control band and reactor pressure is being maintained with steam line drains and main turbine bypass valves.

    "Nine Mile Point unit 2 experienced an unusual event due to a small fire in the turbine building that was immediately extinguished and then reflashed.

    The fire was declared out at 1119 [EST], 2/1/18.

    The fire was caused when steam leak repair injection equipment failed and leaked onto hot piping.

    There was no equipment damage or impact to plant operation.

    The fire was extinguished by the fire brigade. Offsite assistance was not required."

      Science can in one instance be brilliant

      Then totally be unable to just grasp that simple fact. Our human organism can handle bananas. It can't handle the products of nuclear fission. I can't keep beating my head against the wall about the K-40 thing.

      The scientists can explain why the sky is blue, but if one day the sky wasn't blue they would just deny it. They would still say the sky was blue and try to explain why it appears otherwise, but it's still blue.

      When I discovered the Fukushima disaster I was fresh out of college (getting near 50 though. Now I just clean for a living and my patience is shot

      Good luck on your persistent inquiry into the matter.

      From the little bit I know, the word Melanin gets used a bit.

      There are three types in mammals.

      Pheomelanin, Eumelanin, and Neuromelanin

      There are many studies on Pheomelanin, (the red head in everyone), and UV light. Some are saying it is UV net negative to have more.

      Neuromelanin, (brain matter pigment). Yes, protection evolved.

      There are also two subtypes of Eumelanin,(our color, or pigment).

      What most refer to as Melanin.

      A little makes improved vitamin D generation, a lot and you have trouble making that from the Sun.

      Pheomelanin as well as eumelanin is present in human epidermis.

    I got a great idea for Fukushima, and the nuclear problem in general.

    A while back a woman caught my attention by smelling soooo good. It was like a Disney moment: little sparkles floated around her and I was entranced. I asked her what she was wearing. It was Bath and Body work "Thousand Wishes" fragrance.

    If our government has trillions of dollars to spend, I say we use helicopters to dump "Thousand Wishes" on all the nuclear plants, employees, and proponents. At least they can smell good. Cheaper than actually doing something about — like that's going to happen

    Here's 2017 December data for Grand Goof. Only the date and message because this site doesn't tab data fields and the power fig would offset the msg field.

    20171223 HOLDING POWER
    20171216 24 HOUR XENON HOLD
    20171211 INCREASING POWER TO 100%

    • freebywill

      The entire years data can be viewed here

      This data is compiled by scraping the NRC daily RS data and dumping it into a spreadsheet so it can be sorted by unit to get the continuous listing.
      It's formatted as a push-down stack of entries by date so it reads from the bottom up.

      This unit only logged 124 days at 100 % thermal power which usually equates to 100 % electrical power.
      They sync to the grid around 16-18 % power so they may be adding power to the grid from that point on,
      I have no info on what the minimum thermal power to produce electrical power is.

      Exited shutdown on Jan 29, 2017 that had been ordered by the NRC for one of those major inspections starting on Sept 08, 2016.
      From reading the data it makes one wonder just what the NRC inspected.

      The year is plagued by equipment breakdowns and constant references to ' rod pattern adjustments ' and ' rod sequence exchanges. '
      From a read run once ( sry forgot to log link ) I think the rod pattern adj/sequence exch are adjustments in the control rod assemblies and is done to balance the core to keep hot spots from forming.
      There seems to be a lot of flow problems which are most likely due to the constant pump problems.
      The frequent start/stops of the reactor also cause xenon buildup issues.

      Because of the 28 day data hide by the NRC I can't see specifics so far this year but this unit hasn't been able to achieve 100 % power and is currently in it's second…

    Long Islanders Issue Call to Arms on ‘Radioactive Plume’

    February 2, 2018 AMANDA OTTAWAY

    CENTRAL ISLIP (CN) – Long Island is on the brink of “environmental catastrophe,” residents claim in a federal complaint, accusing New York and U.S. authorities of letting radioactive waste spread in the groundwater.

    Filing suit Thursday in U.S. District Court, the group Long Island Pure Water says suburban Bethpage owes its “plume of radioactive material” to the decades of improper waste handling carried out by the U.S. Navy and the aircraft manufacturer now known as Northrop Grumman.

    “These claims are pure fiction and the facts are clear – the public is not exposed to or drinking radium contaminated water,” spokeswoman Erica Ringewald said in an email.

    Residents say the presence of radium in one local well caused the water district to shut it down.

    But tens of thousands of people receive their drinking water from the 25 public and private wells southeast of the Navy-Grumman site in Bethpage, and the complaint says “several [of the] wells are known to be threatened by the plume.”

    Radiation exposure from depleted uranium: The radiation bystander effect.

    Depleted uranium (DU) is a radioactive heavy metal used primarily in military applications. Published data from our laboratory have demonstrated that DU exposure in vitro to immortalized human osteoblast cells (HOS) is both neoplastically transforming and genotoxic. In vivo studies have also demonstrated that DU is leukemogenic and genotoxic. DU possesses both a radiological (alpha particle) and chemical (metal) component but is generally considered a chemical biohazard. Studies have shown that alpha particle radiation does play a role in DU's toxic effects. Evidence has accumulated that non-irradiated cells in the vicinity of irradiated cells can have a response to ionization events. The purpose of this study was to determine if these "bystander effects" play a role in DU's toxic and neoplastic effects using HOS cells. We investigated the bystander responses between DU-exposed cells and non-exposed cells by co-culturing the two equal populations. Decreased cell survival and increased neoplastic transformation were observed in the non-DU exposed cells following 4 or 24h co-culture. In contrast Ni (II)- or Cr(VI)- exposed cells were unable to alter those biological effects in non-Ni(II) or non-Cr(VI) exposed co-cultured cells.

    • Jebus Jebus

      Transfer experiments using medium from the DU-exposed and non-exposed co-cultured cells was able to cause adverse biological responses in cells; these results demonstrated that a factor (s) is secreted into the co-culture medium which is involved in this DU-associated bystander effect. This novel effect of DU exposure could have implications for radiation risk and for health risk assessment associated with DU exposure.

    Hey mister, your rust bucket is leaking. Here are some examples of how stations are hiding reactor problems from public view.

    Normally we get alerted to problems when an Event Notice (EN) is posted, but as noted in a previous post problems are reported to the NRC that don't require an event notice. One of the things they use is to classify a problem as 'planned maintenance' so they can avoid filing an EN and alerting the public.

    Here are some examples of recent problems.

    20171211 FORCED OUTAGE – REPAIR RCS LEAK (LESS THAN 0.1 GPM) [ 2 days ]



    20171009 SCHEDULED MAINTENANCE OUTAGE [ 10 days ]


    In each of these cases the unit was at 100 % before Shutdown. No Auto or Manual SCRAM, no RPS or other safety system actuation, no other item that exceeds technical or operating specification so they don't have to post an EN.

    None of these events appear to have released anything into the environment at the time of the event, but the sneak thing they do is collect any leaked water, store it in tanks, and then discharge it a little at a time.

    NPS – Nuclear Poison Spewer – always leaking all the time.

    "At 0445 [EST] on February 4, 2018, […] inoperable containment penetration thermal relief check valves 1-CKV-31-3407 and 1-CKV-31-3421 associated with one train of the Containment Incore Instrument Room Chiller system.

    During surveillance testing, the thermal relief check valves failed to open and pass flow as required by acceptance criteria.

    The two penetrations were subsequently drained and isolated in accordance with the surveillance procedure to remove any thermal expansion concerns.

    Technical Specification 3.6.1 was exited February 4, 2018 at 0512 once the two penetrations were drained and isolated.

    "The purpose of the thermal relief check valves is to allow flow from an isolated penetration back into the upstream containment piping to prevent over-pressurization due to thermal expansion.

    Over-pressurization of an isolated containment penetration could potentially cause the penetration or both of the isolation valves to fail and provide a direct flow path to the environment from the potentially contaminated containment atmosphere under certain Design Basis Accidents.

    [ unknown if these are the same type of check valves mentioned in a PART21 notice I posted previously. ]

    The Nuclear Regulatory Commission's recent inspection of Indian Point as part of a series of requirements imposed on the nation's nuclear power plants after the Fukushima disaster in 2011 turned up one minor problem. Inspectors found that at temperatures below freezing, the diesel fuel being used could solidify and damage portable emergency equipment.

    The problem is of very low safety significance and the inspection finding was classified as "Green," Sheehan said. The NRC inspectors identified the condition and the licensee took immediate actions to ensure the equipment was supplied with suitable diesel fuel that would not be susceptible to this condition, he said.

    "The announcement from the Exelon Corp. that the Oyster Creek nuclear plant will shut permanently in October, ahead of schedule, was billed as an economic and energy issue. The reality is that shutting the oldest nuclear reactor in the U.S. is a health issue.
    After October, production of huge amounts of more than 100 radioactive waste products after splitting uranium atoms — the same chemicals found only in reactor operations and atomic bomb explosions — will cease.

    Enormous amount of waste — the equivalent of what was released at the catastrophic Chernobyl meltdown — will remain at the plant, stored in pools of constantly-cooled water (recent waste) or steel-and-concrete casks (older waste). These chemicals, mostly plutonium, strontium, and cesium, must be secured for thousands of years, away from any human contact."

    Maybe if I simplify…


    According to Tokyo Electric Power Company (Tepco), radiation levels of eight Sieverts per hour (Sv/h) have been discovered within the Fukushima nuclear power plant, which was destroyed after a massive earthquake and a tsunami in March 2011.

    While 8 Sv/h is deadly, outside of Fukushima's Reactor Number 2 foundations of a much higher level of 42 Sv/h was detected.

    A strange occurrence, and experts are still arguing what caused the discrepancy. One possible explanation is that cooling water washed radioactive material off debris, taking it somewhere else.

    But here's a truly terrifying catch: according to the report, Tepco highly doubts the new readings, because, as was discovered later, a cover was not removed from the robot-mounted measurement device at the time of the inspection, NHK World reports.

    I don't know how else to say it. It's in the ground.

    New Unit 2 Probe Shows Low Radiation And Uniform Temperature
    “Temperatures and radiation readings along the probe route show consistently low radiation levels and no fluctuation in temperature. The radius of the pedestal is 3 meters. If there was any significant amount of nuclear fuel containing debris in the center of the pedestal the radiation levels would have been much higher. TEPCO’s claim that they found fuel debris may only be partially true. They found some fuel debris but what they found as documented so far didn’t contain considerable amounts of nuclear fuel pellets in the melted debris. This raises new questions about TEPCO’s refusal to release all of the footage and still images from this work including the central pedestal floor area.”

    What does this mean?
    Answer: No corium present.

    Earlier study showed no corium in the reactor vessel.
    Low radiation means no corium in pedestal area.

    No videos of the floor of the pedestal were released by Tepco.
    What is Tepco and Japan hiding here?
    Is the corium at the bottom of a corium lava tube?
    Is the corium ex-containment vessel?
    Where oh where is that damn corium, eh, Tepco?
