San Onofre Nuclear Generating Station: A brief history

Ten years ago this month, on June 7, 2013, Southern California Edison (SCE) communicated the decision to permanently shutter the San Onofre Nuclear Generating Station (SONGS). The decision set in motion the decommissioning of a plant that had provided steady baseload power for the region since 1968 during a period of tremendous growth in the western United States. In the end, issues presented by the planned replacement steam generators that were intended to support future plant operations proved too large of a hurdle, and the plant was forced to retire.

The San Onofre Nuclear Generating Station (SONGS) recently shared a few videos on its YouTube channel, showing recent progress Southern California Edison has made in dismantling the plant’s turbine building. Decommissioning of the nuclear power plant, which permanently ceased operations in 2013, is being conducted by SONGS Decommissioning Solutions, a joint venture of EnergySolutions and AECOM.

A nearly yearlong effort to de-tension and remove more than 400 steel cables, known as tendons, from the two containment domes of the San Onofre Nuclear Generating Station (SONGS) was recently completed, with only one minor first aid incident recorded, according to Southern California Edison.

Southern California Edison has released a three-volume set of plans supporting the off-site relocation of the spent nuclear fuel currently stored at the San Onofre Nuclear Generating Station. According to SCE, the release of the Action Plan, the Strategic Plan, and the Conceptual Transportation Plan constitutes a significant milestone in a process that began with the 2017 settlement regarding the coastal development permit issued for San Onofre’s expanded spent fuel storage installation.

At the same time, in an effort to urge the federal government to find a permanent solution to the nation’s inventory of commercial spent fuel, SCE and the counties of Orange and San Diego announced on March 15 the formation of a stakeholder coalition, Action for Spent Fuel Solutions Now.

“SCE and our partners and stakeholders have a genuine opportunity to bring people together with a shared interest to prepare and advocate for the relocation of the spent fuel away from the coast,” said Kevin Payne, SCE’s president and chief executive officer. “It is clear that to make tangible progress on this issue, the federal government must act. Rather than wait for this to happen, we are going to be a catalyst for change.”

Information about the coalition, including how to join, is available on its website.
