The Diablo Canyon Power Plant is an electricity-generating nuclear power plant near Avila Beach in San Luis Obispo County, California. Since the permanent shutdown of the San Onofre Nuclear Generating Station in 2013, Diablo Canyon is the only operational nuclear plant left in the state. The plant has two Westinghouse-designed 4-loop pressurized-water nuclear reactors operated by Pacific Gas & Electric (PG&E).

The facility was the subject of controversy and protests, both during its construction and operations, including nearly two thousand civil disobedience arrests in a two-week period in 1981.

Diablo Canyon Power Plant is on approximately 900 acres (360 ha) of land located just west of Avila Beach, California. The power-producing portion of the plant occupies around 12 acres (4.9 ha). Together, the twin 1100 MWe reactors produce about 18,000 GW·h of electricity annually (8.6% of total California generation and 23% of carbon-free generation), supplying the electrical needs of more than 3 million people. Though it was built less than a mile from the Shoreline fault line, which was not known to exist at the time of construction, and is located less than three miles from the Hosgri fault, a 2016 NRC probabilistic risk assessment of the plant, taking into account seismic risk, estimated the frequency of core damage at one instance per 7.6 million reactor years.

The plant is located in Nuclear Regulatory Commission Region IV. In November 2009, PG&E applied to the Nuclear Regulatory Commission (NRC) for 20-year license renewals for both reactors. In June 2016, PG&E announced that it plans to close the two Diablo Canyon reactors in 2024 and 2025. Full decommissioning of the plant is estimated to take decades and cost nearly 4 billion dollars.

Diablo Canyon was built and entered service despite legal challenges and civil disobedience from the anti-nuclear protesters of the Abalone Alliance. Over a two-week period in 1981, 1,900 activists were arrested and sent to jail for protesting at Diablo Canyon Power Plant, including musician/activist Jackson Browne. It was the largest arrest total in the history of the U.S. anti-nuclear movement.

Protests over Diablo Canyon

Over a two-week period in 1981, 1,900 activists were arrested at Diablo Canyon Power Plant. It was the largest arrest in the history of the anti-nuclear movement in the United States. Specific protests included:

August 6, 1977: The Abalone Alliance held the first blockade at Diablo Canyon Power Plant, and 47 people were arrested.

August 1978: almost 500 people were arrested for protesting at Diablo Canyon.

April 8, 1979: 30,000 people marched in San Francisco to support shutting down the Diablo Canyon Power Plant.

June 30, 1979: about 40,000 people attended a protest rally at Diablo Canyon.

September 1981: more than 1900 protesters were arrested at Diablo Canyon.

May 1984: about 130 demonstrators showed up for start-up day at Diablo Canyon, and five were arrested.

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.The split led to the formation of Friends of the Earth, led by David Brower.
