mdsolar writes with news that the aging reactor fleet in the U.S. will likely see units hitting 80 or more years of use before being decommissioned. From the article: "Officials of the US Nuclear Regulatory Commission and the nuclear power industry expect the first application to be filed with the agency in 2018 or 2019 for a license renewal to operate a power reactor or reactors beyond 60 years. At a Nuclear Energy Institute forum in Washington Tuesday, neither NRC nor industry officials named specific plants considered likely to apply, and it was not clear from their remarks if any nuclear operator has yet volunteered to be the first to apply." Also see the staff report on preparing for the first applications. The proposed operating license changes would place no limit on the number of 20 year extensions, so perhaps a few reactors will end up in operation for a full century (if there's anyone left who can remember how to operate them then).
