UNITED STATES NUCLEAR REGULATORY COMMISSION SACRAMENTO MUNICIPAL UTILITY DISTRICT RANCHO SECO NUCLEAR GENERATING STATION DOCKET NO. 50-312 H_0TICE OF ISSUANCE OF ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (NRC) is considering approving a Sacramento Municipal Utility District (SMUD) proposed decommissioning plan for its Rancho Seco Nuclear Generating Station (RSNGS) and issuing an order authorizing decommissioning of RSNGS. The decommissinning plan proposed by SMUD involves placing and maintaining Rancho Seco in a condition that allows it to be safely stored (SAFSTOR) until the year 2008, then dismantlement and removal of the reactor pressure vessel, core internals, and contaminated systems and structures.
Description of Proposed Action On June 6, 1989, voters of Sacramento, California decided by non-binding referendum that SMUD should no longer operate Rancho Seco. On June 7, 1989, Rancho Seco was shut down after approximately 15 years of operation. All nuclear fuel was removed from the reactor and is presently being stored in the Rancho Seco spent fuel pool. Approval of the decommissioning plan will allow SMUD to implement the SAFSTOR decommissioning alternative.
Summarv of the Environmental Assessment The purpose of decommissioning a nuclear facility is to take the facility safely from service, and to reduce residual radioactivity to levels that permit release of the property for unrestricted use and license termination.
The NRC staff has reviewed the proposed SMUD decommissioning plan, and 9306210234 930616 PDR ADOCK 05000312 M
pon
supplemental environmental report prepared in accordance with 10 CFR 51.53(b).
To document its review, the staff has prepared an environmental assessment (EA) consistent with 10 CFR 51.95(b), which examined decommissioning alternatives, non-radiological and radiological impacts of decommissioning, and effects of postulated accidents. The alternatives available for decommissioning--DECON, ENTOMB, SAFSTOR, and No Action--are evaluated and discussed in the " Final Generic Environmental Impact Statement on Decommissioning of Nuclear Facilities," NUREG-0586, dated August 1988 (GEIS).
Based on its review of the pr' posed SMUD decommissioning plan, the staff has o
determined that the environmental impacts associated with the decommissioning of RSUGS in accordance with that plan are either bounded by the conditions evaluated in the GEIS or in the NRC Final Environmental Statement related to the operation of Rancho Seco, or are in compliance with 10 CFR Part 50 Appendix 1 annual design objectives for offsite releases or 10 CFR Part 20.
Findina of No Sionificant Impact The staff has reviewed the proposed decommissioning plan in accordance with the requirements of 10 CFR Fart 51. The staff has concluded that there are no significant environmental impacts associated with the proposed action and that the proposed action will not have a significant effect on the quality of the human environment. Therefore, the NRC has determined, pursuant to 10 CFR 51.31, not to prepare an environmental impact statement.
