The document discusses the decommissioning of the San Onofre Nuclear Generating Station (SONGS) in California. Southern California Edison announced in 2013 that it would permanently retire Units 2 and 3 of SONGS. The owners have established principles of safety, stewardship, and engagement to guide the decades-long decommissioning process. A Community Engagement Panel was also established to serve as a liaison between the owners and the public during decommissioning.

Learn more about decommissioning at SONGScommunity.com Southern California Edison (SCE) announced June 7, 2013 that it will permanently retire Units 2 and 3 of its San Onofre nuclear plant. The co-owners of San Onofre have established core principles of safety, stewardship and engagement to guide the decades-long process of decommissioning. SCE established a Community Engagement Panel of citizens and elected officials to serve as a conduit of information and ideas between the owners and the public during the complex decommissioning process. Units 2 and 3 of the San Onofre nuclear plant, located near San Clemente, Calif., safely generated electricity for 30 years. The 2,200 megawatts generated by Units 2 and 3 provided enough power to serve 1.4 million average homes at any point in time. Unit 1 operated from 1968 to 1992. San Onofre is jointly owned by: SCE (78.21 %), San Diego Gas & Electric (20 %) and the city of Riverside (1.79 %). They share responsibility for decommissioning, along with the city of Anaheim, a former owner of San Onofre.

Frequently Asked QuestionsDecommissioning Process Public Engagement The importance of public involvement in decommissioning is reflected in the core principles of safety, stewardship and engagement. SCE remains committed to the local community, and will continue to participate in community events and host education fairs in the surrounding cities so the public can learn more about decommissioning. In addition, SCE established a Community Engagement Panel of citizens and elected officials in February 2014 to serve as a conduit of information and ideas between the owners and the public during the complex decommissioning process. The following principles are central to SCEs goal to make the San Onofre decommissioning a model for the industry: SAFETY We commit to safely decommissioning San Onofre. STEWARDSHIP We are committed to leaving the community better off as a result of having been home to San Onofre for 40 years and we will be open to exploring opportunities for doing so with our landlord, the U.S. Navy, and the community. Substantial dollars have accumulated in Nuclear Decommissioning Trusts through customer contributions and judicious investing, and the owners recognize their legal responsibility to spend those funds wisely and retun any unused money to ratepayers. ENGAGEMENT We are commited to managing the San Onofre decommissioning process in an inclusive, forward-thinking and responsible way. That is why the Community Engagement Panel (CEP) was established. * * * * How does San Onofre manage used nuclear fuel? San Onofre currently stores used nuclear fuel safely and securely using a combination of technologies: enclosed, steel-lined concrete pools filled with water (spent fuel pools) and in sealed stainless steel canisters that are housed in reinforced concrete structures (dry cask storage). SCE plans to transfer all used fuel to dry cask storage by 2019. What is an independent spent fuel storage installation? An independent spent fuel storage installation or ISFSI is a facility designed and constructed for the interim storage of spent nuclear fuel and related radioactive materials. The dry cask storage system must meet strict NRC design and performance specifications before the NRC certifies it. San Onofres ISFSI currently has 51 dry storage canisters containing used fuel from Units 1, 2 and 3. Dry cask storage systems are designed to withstand various natural phenomena, such as floods, projectiles from a tornado, seismic events, temperature extremes and lightning strikes. Will the NRC continue to inspect SONGS during decommissioning? As long as used nuclear fuel remains on-site at San Onofre, the site will continue to be licensed and inspected by the NRC, and the used nuclear fuel will be maintained and protected by SCE. The NRC license requires monitoring of spent fuel and extensive, multi-layered security measures. SCE maintains a robust Emergency Plan to ensure public safety and will continue to do so throughout decommissioning. Will SONGSs Emergency Plan change? SCE submitted to the NRC proposed changes to our Emergency Plan (E-Plan) to reflect our permanently defueled status. These E-Plan changes are typical for decommissioning plants in the United States and are subject to approval by the NRC. Pending that NRC action, the station continues to adhere to emergency plan requirements reflective of an operating plant. What is SCE doing to protect the offshore marine environment? The San Onofre Marine Mitigation and Monitoring Program continues under the administration of scientists at the University of California, Santa Barbara, with oversight provided by the California Coastal Commission. The efforts include biological and physical monitoring of SCEs wetlands restoration and artificial kelp reef projects. Q A Q A Q A Q A Q A Southern California Edison (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. The notification, called a Certification of Permanent Cessation of Power Operations, set the stage for SCE to begin planning for decommissioning. The NRC has strict rules governing nuclear plant decommissioning, involving cleanup of radioactively contaminated plant systems and structures, and the removal of the radioactive fuel. Longer term, the process calls for cleaning up radioactivity to allow for unrestricted use of the land. The NRC requires that decommissioning be completed within 60 years, but SCE plans to complete this work within 20 years. The used fuel will be stored safely on-site until the federal government fulfills its contractual obligation to open a permanent spent nuclear fuel storage facility. SCE has developed a detailed plan that spells out specific decommissioning activities and schedules, cost estimates and potential environmental impacts. This plan, called a Post-Shutdown Decommissioning Activities Report, was submitted to the NRC in September 2014 and shared with state officials. As part of the process, the NRC takes public comment, including a public meeting. SCE PLANS TO COMPLETE THIS WORK IN 15 TO 20 YEARS Updated: 12/04/2014
