[6] The birth of the anti-nuclear movement in California can be traced to controversy over Pacific Gas and Electric Company's attempt to build the nation's first commercially viable nuclear power plant in Bodega Bay.
[7] Californian's for Nuclear Safeguards would succeed at placing Proposition 15 on the June 1976 ballot which would have banned new facilities and put additional safety requirements on operating reactors.
[17][18] Specific protests included: During this period there were controversies within the Sierra Club about how to lead the anti-nuclear movement, and this led to a split over the Diablo Canyon plant which ended in success for the utilities.
[7] In 1979, Abalone Alliance members held a 38-day sit-in in Californian Governor Jerry Brown's office to protest continued operation of Rancho Seco Nuclear Generating Station, which was a duplicate[clarification needed] of the Three Mile Island facility.
[25] The salient issues were mostly economic; the plant kept breaking down, and it had been shut from late 1985 to early 1988 for repairs, forcing the district to buy electricity from neighbors.
On June 15, 1990, the Bureau of Land Management published the draft Environmental Impact Statement (DEIS) for the construction of a low-level nuclear waste repository to be located at Ward Valley California.
[32] PG&E announced its decision to pursue license renewal for Diablo Canyon in November 2009, and local officials "came out in support because of the economic importance of the plant and its 1,200 employees and $25 million in annual property taxes".
[33] In April 2011, there was demonstration of 300 people at Avila Beach calling for the closure of Diablo Canyon nuclear power plant and a halt to its relicensing application process.
The event, organized by San Luis Obispo-based anti-nuclear group Mothers for Peace, was in response to the Fukushima nuclear disaster in Japan.
[4][5] In June 2016, Pacific Gas and Electric announced plans to retire the Diablo Canyon Power Plant after its current U.S. Nuclear Regulatory Commission operating licenses expire in November 2024 and August 2025.
