  • Forum Post: Re: What is taking so long?

    Thanks for your replies! I can understand the economics part of it....supply and demand...and demand is down. What I don't get is why it takes the NRC so long for the review.? Sure, it is a money maker for them but when they are reviewing a design like the EPR (that the French approved and...
  • Forum Post: Re: What is taking so long?

    I think the NRC is currently doing a good job. They have said it will take up to 3 years to review a license application. I think this is a reasonable time frame. In the past, the NRC has taken a long time for approving both construction and operation permits. (In the past these were two separate licenses...

    It will take courageous political representatives and caring citizens like yourself to speak up about the unfair restrictions placed on Nuclear energy. The whole regimented and punitive approach needs changing. The application is enormously expensive and the company is out $50 million if they are turned...

  • File: Order to Modify Licenses With Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events

    The attached Order gives guidance and strategies if the loss of power, motive force, and normal access to the ultimate heat sink to prevent fuel damage in the reactor and SFP, affected all units at a site simultaneously. This Order requires a three-phase approach for mitigating beyond-design-basis external...
  • File: Order to Modify Licenses with Regard to Reliable Spent Fuel Pool Instrumentation

    The attached Order requires the plants to install enhanced equipment for monitoring water levels in each plant’s spent fuel pool. The spent fuel pool level instrumentation at U.S. nuclear power plants is typically narrow range and, therefore, only capable of monitoring normal and slightly off...
  • File: Order to Modify Licenses with Regard to Reliable Hardened Containment Vents

    The attached Order applies only to U.S. boiling-water reactors that have “Mark I” or “Mark II” containment structures. The NRC has determined that ensuring adequate protection of public health and safety requires that all operating BWR facilities with these containments have...

  • Forum Post: RE: Who is to blame for the retiring of San Onofre Nuclear Generating Station (SONGS) ??

    I think the MHI steam generators are the ultimate reason they have to shut down the plant but if the NRC response was more timely, that would probably prevent this decision. There needs to be a "elevated level" for the NRC response when it comes to making these decisions that impacts the power...
