License Renewal

license renewal process

Pacific Gas and Electric Company (PG&E) has applied for a 20-year extension of its operating licenses for the Diablo Canyon Nuclear Power Plant. The current operating licenses for Diablo Canyon’s two nuclear reactors expire in 2024 and 2025, respectively. PG&E has applied to continue operations until 2044/2045.

Mothers for Peace has challenged this license extension.  Pertinent documents can be found below.

2016 - 05 - 19 Proposed Amendments to SB 968

California Senator Bill Monning has put before the California Senate SB 968.

San Luis Obispo Mothers for Peace is one of 30 organizations going on record as opposing SB 968.

2016 - 03 - 23 Thirty Organizations Oppose Diablo Canyon Bill SB 968

Thirty environmental, health and other organizations today announced their opposition to California state legislation that would mandate an analysis of purportedly negative – but not positive – impacts of shutting down the Diablo Canyon nuclear power plant. In a formal opposition letter, the groups say SB 968 could amount to “a state- ordered piece of advocacy for forces pushing for Diablo Canyon to operate far beyond its original design and license life. This could have great negative impacts on California. We recognize that this is not the intent of the author or co- authors, but nonetheless conclude there would be serious unintended consequences of the bill.”
