U.S. nuclear plant shuts down due to leaks: “Leakage has increased for unknown reasons” — “Exact location of the leakage has not been determined”

Enformable: Palisades nuclear power plant shut down due to leaks […] The Palisades nuclear power plant shut down on Sunday morning, just after 1 am, due to a leak from the Safety Injection Refueling Water Tank.

CBS DetroitMore Problems At Palisades Nuclear Power Plant […] The plant is along Lake Michigan’s shoreline in Van Buren County’s Covert Township, about 80 miles east-northeast of Chicago. Plant operators said they acted after “water leakage from the tank exceeded a site threshold.”

MLive.com: Palisades nuclear power plant has been shut down for repairs, according to officials at the plant. […] Plant operators shut down the plant when water leakage from the tank exceeded a site threshold.

AP: The Nuclear Regulatory Commission says Sunday’s shutdown happened after the water tank exceeded a 38 gallon daily leak limit set in a 2012 letter that followed the earlier shutdown.


NRC:  The exact location of the leakage has not been determined at this time. The Plant will be taken to Mode 5. The licensee has been operating with SIRW leakage at a rate of less than 34 gallons per day. The leakage has increased for unknown reasons to a calculated value of approximately 90 gallons per day.

    A high school chemistry teacher exposes the vulnerbility of U.S. NPPs. Very basic explication of their basic architecture, useful for newbies. Wants to start a foruum if someone will help.

    COVERT TOWNSHIP, MICH. — Operators of the Palisades Nuclear Power Plant in southwestern have removed it from service because of a repeat water leak from a tank that caused seepage into the control room last year.

    "seepage into the control room", a yet-further continuation of the Nuclear Follies.


    Commenter "Gino Schafer · Detroit, Michigan

    This tank is on the roof of the auxiliary building (Aux building)."
    So this means there's a leak in the roof of the Aux building that seeps into the Control Room.

    Priority at Palisades? Collect the salary, only.


      great article Trawling4Trolls. Thanks for posting the link. If this guy is employed with the New Jersey educational system, they'll likely be doing their best to remove him from his teaching post. He too honest about the problem.

      Thanks again…

        Hostage-taking as an attempted art form in the U.S.

        Imagine being an engineer at Palisades, knowing exactly what's needed to keep key electrical equipment bone-dry, and watching management consistently refuse to authorize the simple measures to ensure that bone-dry.

        Deprived of the 'freedom' to take your physical life hostage, management opts for the aggression of taking your imagination hostage in the wondering how long it'll be before management kills untold numbers.

        With regulators' permission, of course.

        I'm still waiting for Jaczyko to tell us what exactly happened at Ft. Calhoun, or to come out with his support for modular reactors. It'll be one or the other.

    Ahh hell whats 90 gallons a day of radioactive water? 630 gallons a week. 32,760 gallons per year. They do not know where the leak is but they know how much. What a circus.

      Already has contaminated Lake Michigan. Before Sunday’s shutdown of Palisades Nuclear Power Plant, about 79 gallons of diluted radioactive water were released into Lake Michigan, the Nuclear Regulatory Commission said Monday, May 6. […]. Oh, and the water just NOW made its way there, but didn't before, even though 34 gallons have been leaking EVERY day (but hey, what's ..up until it started leaking 90 gallons a day? Humph. What a coincidence.
      There are 7.48 gallons in cubic foot and 748 gallons in one hundred (100) cubic feet (hcf). In order to express large volumes of water use, this water use is expressed in acre feet numbers. One acre foot equals 43,560 cubic feet or 435.6 hundred cubic feet and is equivalent to 326,700 gallons. Just imagine one acre foot of land covered by one foot deep in water. So that means that in 10 years, Lake Michigan would have an acre of radioactive water. How many years has Palasades been leaking an average of 34 gallons a day…after the amount of leakage perfectly permissable had to be SET in 2012 at 38 gallons a day (how much was it before that?)? Oh, yeah, they didn't say.

    More important is what is in the leaked water..the radiation. Oh..and just thinking about a leak, from a OVERHEAD tank, is the flow pattern. Are they measuring about what they have FOUND leaked into the 'control' room(s)..or from the tank contents/loss of contents. Big difference.

  • weeman

    I doubt it is radioactive water leaking, but what it tells me is that the plant is poorly operated and have no preventive maintenance program in place, I find it ridicules that something with the potential of killing millions is not kept in pristine condition, the plants should be run under the same maintenance procedure that you use on nuclear submarines and aircraft carriers etc. No money is spared.
    I know we will have to ween our selfs of nuclear power, untill that time the army needs to run these facilities with a open cheque book.
    I am not comfortable at all allowing independant operators who's main objective is to make money for share holders at the expense of maintenance. No no no no no no.

    This old facility has been leaking for some time…U.S. Rep. Ed Markey (D-MA), who is running for John Kerry's open U.S. Senate seat on June 25th in a special election as the Democratic candidate, made known to the world the "crisis in the control room" at Palisades on 6/12/12–including the fact that the leak was being caught in buckets, including one right next to the central console panel in the control room.

    The NRC regulations allowed the leak to continue until it reached the current rate at which it will now have to be found and fixed. Many concerned citizens have urged the NRC to take action and get the leak fixed sooner. The NRC and Entergy who operate Palisades let the leak continue saying it was not really a problem. If it wasn’t a problem why did they fail to tell former NRC Chairman Jaczko about it when he visited the facility about a year ago? Their failure to tell him about the leak was a bit scandalous and before Jaczko left the NRC he asked for an investigation regarding the incident.

      A major accident at Palisades would contaminate Lake Michigan, one of the largest sources of fresh drinking water in the world. Palisades has an embrittled reactor pressure vessel the worst in the country! It also has age degraded steam generators, an age degraded reactor lid and an age degraded Safety Refueling Injection Water storage tank. The dry cask storage outside the facility is not safe either. The Palisades Nuclear Facility has had numerous unplanned shutdowns in the last year or so and people do not feel it is safe with it continuing to be in operation.

      After they get Palisades up and running how many days will it operate before the next unplanned shutdown? My guess is 75 days. Anyone else care to guess?

        Aren't they the least little bit concerned that water leaking into the "Control Room" could short out reactor control circuits?

        If Palisades NPP screws up big time,
        And South Haven has to be permantly evacuated,
        We could lose the idler Bar,
        Then I'd really be pissed off!

        Recently Putin was chiding the North Koreans about their behavior, saying something to the effect that the response they were inviting would make Chernobyl look like a picnic. You can only wonder what type of people management & engineers at these nuke plants must be like to even begin to invite events that can produce the genetic shuffle-type effects like seen in the Balkans and Iraq. Stuff like human hands .. growing out of shoulder joints ?!

        Beautiful children's futures reduced to that type of f#*ked-up effects! Hello.

  • We Not They Finally

    Palisades is NOT "a disaster waiting to happen." It's one that has already happened many times over. Sometime within the last two years (I think Dutchsinse noted it, but there were others), the radiation in that area spiked HORRENDOUSLY. So they shut down the monitors and said that it was "a false reading." Even the NRC calls it one of the three worst nuclear plants in the U.S. Jail time for repeated violations by their management would set a good public example. Fines is just total crap (excuse), because the real "fine" is loss of lives.

  • We Not They Finally

    They had said it was O.K. to have 38 gallons of radioactive water leaking each and every day?? Chances are that it is way worse, but even that much is insanity.
