Decommissioning San Onofre Nuclear Generating Station
Southern California Edison plans to safely decommission San Onofre in full compliance with state and federal regulations. We are doing so in a timely manner, while making plans and updates available to the public.
We are committed to meeting our responsibilities and doing the right thing for our region throughout this process. Our core principles are Safety, Stewardship and Engagement.
SCE formally notified the Nuclear Regulatory Commission (NRC) on June 12, 2013 that it had permanently ceased operation of Units 2 and 3 on June 7, 2013. The notification, called a Certification of Permanent Cessation of Power Operations, set the stage for SCE to begin preparations for decommissioning and dismantling the plant.
Decommissioning is a well-defined NRC process that involves safely transferring the used nuclear fuel into storage, followed by the eventual removal and disposal of radioactive components and materials from the site. Any residual radioactivity will be reduced in a manner and to a level that is safe for unrestricted use by SCE’s employees and the public. This will support the termination of SCE’s NRC license and return of site to its owner, the U.S. Navy.
Safely Dismantling SONGS
Dismantlement is expected to begin first quarter 2020 and will involve the deconstruction of above-grade structures associated with Units 2 and 3 in compliance with NRC requirements, as well as the partial removal of offshore undersea conduits (large pipes) and offshore buoys and anchors.
SONGS Decommissioning Solutions (SDS) is our decommissioning general contractor. The project is expected to create about 600 jobs during the 8-to-10-year dismantlement phase, and the majority of the labor force will be hired locally from the San Diego region.
Here, you’ll find detailed information about how we’re reducing public impacts and maintaining public access to areas close to the site.
Our Guiding Principles
SCE and the current and former San Onofre owners responsible for decommissioning have established core principles of Safety, Stewardship and Engagement to guide the long and complex decommissioning process. These guiding principles support SCE's vision of making the decommissioning of the San Onofre nuclear plant a model for the nuclear industry.
