. DIVISION OF LICENSING U S NUCLEAR REGULATORY COMMISSION WASHINGTON D C 20555 DOC'(ET 50-312 RANCHO SECO NUCLEAR GENERATING STATION UNIT NO 1 RANCHO SECO LIVING SCHEDULE The District anticipates that the NRC will soon approve proposed License Amendment 106 "The Living Schedule Plan for Rancho Seco Nuclear Generating Station". Responding to the request of the NRC Project Manager, Syd Miner, the District is submitting (Attachment I) its most recent Rancho Seco Living Schedule, dated August 9, 1985 and issued as Revision 00. The District will transmit approved Living Schedules to the NRC dated and with now Revision nuEs t

~

Attachment II is a brief summary of Living Schedule changes since the last Living Schedule, dated October 1984. As noted in both Attachments, Rancho Sec.o is now in Cycle 7, so a number of modifications are shown as completed. The District has listed items as " completed" when Startup has successfully finished testing and upon acceptance by Nuclear Operations.

Also, the attached Living Schedule now includes additional items and covers the period from Cycle 7 to mid-Cycle 10.

The District trusts this information will lead to the prompt approval of proposed License Amendment 106. Should you have any further questions, contact Jerry Delezenski at Rancho Seco.
