history
.jpg){kind=spacer}
In 1966, SMUD bought eight square kilometers in southeast Sacramento County for a nuclear power plant that was being built at Clay Station, 25 miles southeast of downtown Sacramento. Construction of the nuclear power plant began on April 1, 1969. In the early 1970s, a small pond was expanded to a size of 0.6 km 2 in order to guarantee the emergency water supply for the power plant in the event of a power plant fire. The lake got its water from the Folsom South Canal and has no relation with the power station in the daily water supply. On October 13, 1974, the reactor was synchronized with the power grid for the first time and went into commercial operation on April 17, 1975.
The final shutdown took place through a referendum on June 7, 1989, despite the fact that the operating permit was still in place until October 11, 2008. This political decommissioning decision was caused by an incident the year before: the reactor had to be emergency cooled. Because considerable embrittlement had already formed on the reactor vessel made of special steel as a result of the permanent neutron bombardment from the core, there was a threat of a so-called pressurized thermal shock from the cold emergency cooling water. That is, the reactor vessel was expected to burst.
Decommissioning work has been underway since 2005. You can now fish and camp near the former factory premises. After the factory was closed in 1989, it was converted into a public park, which is still called Rancho Seco Park today . SMUD now uses the park's income to finance all park operating costs. The cooling towers remain a familiar part of the local landscape. The area is home to the airstrike sirens that are still active, which would have warned people about the meltdown at Rancho Seco. A solar power plant with an output of 3.9 MW and a natural gas-fired power plant, the Consumnes Power Plant , which went into operation in 2006, are now also on the site .
The reactor
The pressurized water reactor from Babcock & Wilcox had a thermal output of 2772 MWt, a net electrical output of 873 MWe and a gross electrical output of 917 MWe.
