The disused San Onofre Nuclear Generating Station ( English San Onofre Nuclear Generating Station , SONGS ) is located in California in the Pacific , at San Onofre State Beach ten miles south of San Clemente in northwestern San Diego County and the San Onofre State Park enclosed. The nuclear power plant consists of three blocks, the last two of which were shut down in June 2013. The first reactor has already been dismantled, making it the first and only reactor block in California to be dismantled. The Vallecitos , Humboldt Bay and Rancho Seco nuclear power plants , which were shut down much earlier, have not yet been dismantled (as of 2014).

The operator is Southern California Edison (SCE); the nuclear power plant is owned by Southern California Edison (SCE) (78.21%), San Diego Gas & Electric (20%) and the city of Riverside (1.79%). The power plant stands on 34 hectares of land.

The reactors

The first reactor was a first generation pressurized water reactor ; it was built by Westinghouse . The net output was 436  MW , the gross output 456 MW. Construction began on May 1, 1964, the reactor was first synchronized with the power grid on July 16, 1967 and went into commercial operation on January 1, 1968. It was shut down on November 30, 1992.

The second reactor, built by Combustion Engineering , is also a pressurized water reactor, but with a net output of 1070 MW and a gross output of 1127 MW. Construction began on March 1, 1974, it was synchronized with the power grid for the first time on September 20, 1982 and went into commercial operation on August 8, 1983.

The third reactor is identical to the second. Construction also began on March 1, 1974, it was synchronized with the power grid on September 25, 1983 and went into commercial operation on April 1, 1984.

Geological environment

In the sea, ten kilometers from San Onofre, there are three geological fault lines , and the Cristiano moat is less than one kilometer away. Three other very active fault lines are located 35, 70 and 90 kilometers away, one of which is the well-known San Andreas Trench .

The location of the site is described as one of the most dangerous in the world due to the earthquake hazard. There are more than 7.4 million people within 50 miles, mainly in the major cities of Los Angeles and San Diego .

According to the operator, the power plant is designed for earthquakes up to magnitude 7.0.

Incidents

On February 1, 2012, radioactive gas leaked from a pipe in an adjacent building, causing the reactor adjacent to the building to shut down.

Decommissioning and dismantling of units 2 and 3

The operating company SCE announced on June 7, 2013 that it would finally shut down the power plant for economic reasons. The reactors had already been shut down in 2012 due to serious problems (more than 1,300 ailing tubes were found in both reactors). The uncertainty as to whether and when the identified extensive damage to the power plant could be repaired led to the decision. In addition, the rising costs of aging reactors and the great competition from gas-fired power plants had a negative effect on profitability.

The operator put the cost of dismantling the facility at around $ 4.4 billion in August 2014. It's supposed to last two decades. Highly radioactive reactor components are to be stored in steel canisters on the power plant site after dismantling, and parts that are less heavily contaminated are to be brought to repository in Texas and Utah. In June 2013, costs of $ 3 billion were expected.
