The NRC has terminated License No. DPR-54, held by Sacramento Municipal Utility District (SMUD), for Rancho Seco in Herald, California, and has approved the site for unrestricted release. Accordingly, the existing indemnity agreement between SMUD and the NRC has been terminated.

Rancho Seco initially went critical on September 16, 1974, and began commercial operation on April 18, 1975. On June 7, 1989, SMUD permanently terminated nuclear power operations at Rancho Seco. On December 8, 1989, SMUD completed defueling the reactor. On March 17, 1992, the NRC amended the Rancho Seco operating license to “Possession Only” status (ADAMS Accession No. ML17283A071). On March 20, 1995, the NRC issued the Rancho Seco Decommissioning Order. The Order authorized SMUD to decommission the facility and accepted the Rancho Seco decommissioning funding plan. SMUD began actively decommissioning Rancho Seco in February 1997. In March 1997, SMUD revised the Rancho Seco Decommissioning Plan to conform to the content requirements of the Post Shutdown Decommissioning Activities Report.

On June 30, 2000, the NRC issued Materials License SNM-2510 for the Rancho Seco Independent Spent Fuel Storage Installation (ISFSI). This site-specific license authorizes SMUD to store Rancho Seco spent fuel at the Rancho Seco ISFSI. The licensee completed transferring all of the spent fuel to the ISFSI on August 21, 2002. All of the spent fuel is now stored at the ISFSI. The ISFSI is a separately licensed facility located outside the operating licensed site. On October 10, 2002, NRC approved a license amendment that eliminated the security plan requirements from the operating licensed facility (ADAMS Accession No. ML022840145).
