NRC approves Diablo Canyon license renewal, extension
The Nuclear Regulatory Commission has approved Pacific Gas & Electric’s application to extend the operating licenses for Diablo Canyon nuclear power plant’s two pressurized water reactors by another 20 years.
Thursday’s approval means Diablo Canyon-1 and -2 can now operate until November 2, 2044, and August 26, 2045, respectively, if California lawmakers agree. A 2022 state law requires the California Legislature to approve any extension of operations at Diablo Canyon that goes beyond 2030.
Plenary Session
Wednesday, June 16, 2021|10:00–11:30AM EDT
The aggressive goal of net-zero carbon emissions by 2050 for the U.S. power sector presents a number of challenges with respect to energy portfolio management that is influenced by numerous factors including regulated versus deregulated energy markets, regional variations in future carbon-free/carbon-neutral energy sources, and economic drivers. Expansion of nuclear energy, which currently provides 55% of carbon-free electricity, has the potential to be a cornerstone of future energy strategies. This panel will discuss the future role of nuclear energy deployment within the context of energy portfolio management and net-zero carbon goals from the viewpoint of US utilities and energy suppliers.
