Renewing Licenses for Nuclear Power Plants

The NRC issues licenses that allow nuclear power plants to operate for up to 40 years – a time frame originally chosen for economic and antitrust considerations, not technical limitations. The NRC allows plants to continue operation for an additional 20 years beyond the original 40-year period if licensees prove that there are appropriate aging-related programs in place to assure safe operation throughout this period.

Getting a license renewal from the NRC is no small feat for nuclear power plants. The renewal application is reviewed along two tracks: one for safety issues and another for environmental issues. The nuclear power plants must prove they have addressed the technical aspects of plant aging and must also evaluate the potential impact on the environment if the plant operates for another 20 years. The NRC closely reviews the application and conducts multiple inspections to verify what the plant reports.

There are several opportunities for the public to question environmental impacts or how aging will be managed during the additional years of operation. Additionally, the Advisory Committee on Reactor Safeguards independently reviews the licensee’s application and the NRC staff’s analyses prior to a final determination on a plant’s license renewal request.

Some are wondering why the NRC is continuing to relicense plants when our own task force hasn’t completed work on all the lessons learned from events at the Fukushima Daiichi Nuclear Power Station. What’s important to realize is that the NRC will apply the recommendations from this review, as appropriate, for any changes deemed necessary to improve the safety of operating plants, regardless of whether the plants have been issued renewed operating licenses. So issuing a renewed license now does not exempt the plants from any future requirements that may be issued.

And, of course, all nuclear power plants are subject to an ongoing systematic and thorough NRC oversight to ensure nuclear plant equipment continues to meet safety standards – whether the plants are brand new or 40 years old. This constant NRC oversight ensures a plant will operate safely throughout its life.

    40 years seems like a long time doesn’t it?

    The older the nuclear power plant, the more spent fuel rods piled up. That means that these 40+ year old nuclear power plants have a LOT more radiation involved than younger ones. And those spent fuel rods are sitting in water. With several nuclear power plants located on major fault lines in the U.S., is the NRC aware that it is just a matter of time before another Fukushima happens here?
    NRC, why have you turned a blind eye on all those spent fuel rods that are associated with these aging nuclear power plants. Why is that issue not addressed? They should have been placed in permanent storage all these years and instead, are sitting in storage with much, much more radiation than we care to know about – those storage facilities for the spent fuel rod were only intended to store them for a few years and not for 20 more years.
    A response will be appreciated.

    It’s comforting to see that there is a good amount of regulation involved in the re-licensing process of these plants. I am curious though…how often are these plants inspected by safety officials once they are licensed?

    undoubtedly the key issue is the supervision of the plants at all times, beyond having to renew your license eventually.

    The NRC is simply “rubber-stamping” 20-year license extensions without any rigorous inspection activity to determine exactly how brittle nuclear reactor vessels have become after 40-years of neutron bombardment. The agency is recklessly endangering public health and safety with this unwarranted nuclear experiment. A recent investigation by Associated Press found that nuclear reactors were only designed to operate safely for a 40-year time period. Thus, the NRC’s assertion otherwise is simply disingenuous and not true.

      If you have been involved in reactor license renewal for any length of time, you would know that there has been significant research into how brittle reactor vessel materials become over time. For an accurate review of the AP hatchet piece you reference as if it was a scientific study, see the NEI website.

        @ anonymous AKA Kevin Muggleston, senior consultant
        Don’t you think it is a little disingenuous calling the AP report a hack job, then putting the NEI forward as an unbiased(or “correct”) source? That reeks of the pot calling the kettle black to me.

        The investigation for the AP report began well before the nuclear industry blessed us with the catastrophe at Fukushima. It found among other things that when a plant can no longer meet the historically accepted safety regulations the NRC simply relaxes the regulations until the plant can pass. I can cite examples if you wish. This is similar to what happened in Japan, school children could no longer go to school without exceeding the previous “safe” radiation limit, so the government simply raised what was deemed “safe” ,problem solved.
        The NEI is a blatant pro-nuclear energy front group. They barely even try to deny this. They are against any safety improvements that will cost their corporate paymasters any money. To put them forward as a reliable source is insulting to the intelligence of the people who actually pay attention to this issue.
        Case in point, there was a petition filed with the NRC this year, PRM-50-96, that would have made the nuclear industry implement technology to cool their spent fuel pools in the event of long term damage to the US electrical grid. That it is possible for the grid to be destroyed for years is not debatable. But if anyone wishes to contradict this statement feel free, however realize that I can document what I say, can you? The fixes that would have prevented spent fuel fires a numerous nuclear plant simultaneously are available now and are low cost as far as a corporation is concerned. The NRC received 97 comments on this petition from nuclear industry workers, members of the public living in the kill zone of US plants, and citizens of other countries that would be affected if there was a melt down at a US plant. OF THE 97 COMMENTS 96 WERE POSITIVE, CAN YOU GUESS WHERE THE NEGATIVE COMMENT CAME FROM, THAT’S RIGHT IT CAME FROM THE CORPORATE FRONT GROUP KNOWN AS THE NEI.

        So now members of the public let’s see what the NRC will do. Will it address the serious danger of long-term black out and all the positive comments by citizens and stakeholders or will it follow the advice of the corporate front group known as the NEI. Is the NRC a “captured” agency that is controlled by the industry it is suppose to regulate or does it really serve the “people”? The proof will be in the pudding as they say. We are waiting NRC what say you about the petition PRM-50-96? Will you do what is best for the people or the corporations?

    Historical meteorlogical data used by a nuclear power plant to compute radiation doses is archaic in a climate changing environment particularly when empirical on going data is available or can be required to be available.
