  1. I seem to recall that our NRC recommended to Japan that the evacuation zone be increased from 10 to 50 square miles.

    Perhaps we should get a lot more signs made up.

  2. Wake up America! The nuclear industry has no clue as to how they would handle a disaster and the NRC is wearing blinders. The NRC has already relaxed the fire safety standards for nuclear plants. Also VY (Entergy) has a terrible safety record with ongoing leaks.
    We deserve some safety in our state and our neighbors do too!

  3. Regarding this statement:
    “The Louisiana-based corporation must place an order for uranium fuel by July 7 in order to continue operating the plant through the winter.”
    As understand it, they may continue to operate until the expiration of their license in July 2012, only at a slightly lower (and less profitable) level, with the currently installed fuel.

    1. Responding to Bud Haas. VY’s license expires in March of 2012. There is a regularly scheduled outage planned for October, during which, if there were no threat of closure next year, 1/3 of the fuel rods would be replaced with new fuel. Entergy claimed in its original briefs that this new fuel would need to be ordered by July 7, but in footnote 14 of their reply to the AG’s brief, on page 17, Entergy now says that the date has been extended “to July 22 or 23, 2011.”

  4. VY is upgraded to put out 20% more than the original specs. Cooling towers,radiation leaks, If God forbid my home is contaminated I lose every thing ! Homeowners Will NOT cover losses!!!VY will go out of busness and Our lives are destroyed!!!If Entergy REALLY wants a licence extention get insurance to cover homeowners !!!Can’t buy it aa’y. Well decommisioning makes a lot of sense.I don’t like my potential losses with no gain. God Bless America! Thank You, Michael

  5. Check with the Vermont State Insurance Commissioner for the reason you can’t get homeowners’ insurance for a nuclear accident.

  6. Reports on aging nuclear power plant always mention that they do not have a clear understanding of how nuclear degradation effects reactor systems and sub-systems: the reactor pressure vessel, plumbing, buried pipes, concrete foundations, anchors etc. The reports are extremely candid and to this day the IAEA is still studying the loss of mechanical properties and related “phenomenons”. Researchers use, among other techniques, decommissioned power plants to study the aging process. A popular test is a simple charpy izod instrumented impact test to study hydrogen embrittlement of metal components usually the reactor pressure vessel. This simple instrumented charpy impact test, although somewhat informative, would not pass the laugh test for the aviation industry. To give you some perspective on long term materials testing I was at E. I. Dupont testing laboratories in 1973 when they were trying to get PVC approved by the construction industry for plumbing. They had a room dedicated to row and rows of pressurized PVC pipe that were undergoing continuous testing, at that point they had been under constant pressure for over ten year. I ask their lab manager how long they would continue testing these pipes, he said for another ten years. I have yet to find a similar long term testing scenario for nuclear power sub-systems and components.

    There are no, I repeat no nuclear experts on aging nuclear power plants they are making it up as they go along. By their own admission they do not clearly understand aging dynamics let alone nuclear plants that have run 20% beyond their design capacity. The NRC and their industry use the term “uprate,” this word does not exist in the English language and must stop being used. Oh, for the record, one of a number of areas that these reports on aging sight as problematic are underground pipes. The degradation of underground pipe is well documented, however, the management of Entergy denied that they even had underground pipes. This is beyond belief.

    The quote below is from a 1993 report, page iii.

    Aging Nuclear Power Plants: Managing Plant Life and Decommissioning
    September 1993
    OTA-E-575, Office of Technology Assessment
    NTIS order #PB94-107588
    GPO stock #052-003-01342-8

    “After many years of intensive efforts by the U.S. Nuclear Regulatory Commission and the nuclear power industry, no insurmountable industry-wide safety challenges related to
    plant aging have been identified. There are some notable uncertainties for the longer term,however, that require ongoing research and experience to address. More immediately, many nuclear power plants already face severe economic pressures in the increasingly competitive electric power industry. Regarding decommissioning, experience with
    decommissioning small reactors and with major maintenance activities at large plants suggests that the task can be performed with existing technologies. However, several issues such as waste disposal and site cleanup standards remain unresolved.”

    On page 1 from the same report please see quote below about plant decommissions.

    The past few years brought unexpected developments for
    nuclear plant lives and decommissioning. Since 1989, six nuclear power plants have been retired early, well before the expiration of their NRC operating licenses. Owners of several other plants are investigating the economics of early retirement as well. The owners of the frost large commercial nuclear power plants planned for decommissioning anticipate costs much greater than estimates made only a few years earlier. And after a several year effort, the two lead plants in a program to demonstrate the NRC’s
    plant license renewal process halted or indefinitely deferred their plans to file an application-in one case as part of an early retirement decision. While work continues to develop and eventually demonstrate a regulatory process for license renewal,it will be several years before the first application is filed and acted on. Absent license renewal, about 3 dozen operating nuclear power plants will have to retire in the next 20 years.

    Fast forward to 2000

    This is a quote from a Brookhaven National Laboratory Report entitled: Assessment of Age-Related Degradation of Structures and Passive Components for U.S. Nuclear Power Plants, published in August 2000. Please see quote below, which can be found on page 1 of the report.

    “Structures generally have substantial safety margins when properly designed and constructed. However, the available margins for degraded structures are not well known. In addition, age-related degradation may affect dynamic properties, structural response, structural resistance/capacity, failure mode, and location of failure initiation. A better understanding of the effect of aging degradation on structures and passive components is needed to ensure that the licensing basis (CLB) is maintained under all load conditions.” In the Appendix of structural problems for various reactors there is a note about a crack in the Vermont Yankee structure listed as NA. What do you think happened to the crack when the reactor was run at 120%. Preventative maintenance is only mentioned once in the entire Appendix and I am still not sure what N.A. means. Does N.A. mean not applicable, not available? It was not cleare in the report, at least to me anyway.

    The Vermont Nuclear Power plant must be decommissioned now. Once it has been decommissioned we will see the extent of the damage.

VTD requires that all commenters identify themselves by first and last name. You may wonder why we don't accept anonymous comments. The short answer is: We want to keep the discourse civil.

You might rightly ask, since most online newspapers accept anonymous posts from readers, what makes VTD so special?
