December 31, 1986 Docket No. 50-312 Mr. John E. Ward Sacramento Municipal Utility District Rancho Seco Nuclear Generating Station Post Office Box 15830, Mail Stop No. 291 Sacramento, California 95852-1830
Dear Mr. Ward:
SUBJECT:
MAINTENANCE SURVEY AT RANCHO SEC0 NUCLEAR GENERATING STATION We plan to conduct a survey of the maintenance and surveillance program at Rancho Seco as part of our restart evaluation.
We will schedule the survey after you conclude that the station maintenance program improvements are completed. We suggest that when you conclude that your improvement program is essentially complete, a meeting be held with us at Bethesda, Maryland to review the status of the program and to establish a date for our survey tem to visit Rancho Seco. We are currently targeting the survey during early February 1987 in order that the safety evaluation input on this issue does not become the pacing item in our restart safety evaluation.
Please contact our Project Manaaer, Sydney Miner, to set a date for the meeting.
To assist in scheduling the survey, we are providing in (a) a description of the core activities to be performed by the survey team (Enclosure I) and (b) a list of documents needed by the NRC prior to the above proposed (Enclosure II) meeting.
The reporting and/or recordkeeping requirements contained in this letter affect fewer than ten respondents; therefore, OMB clearance is not required under P.L.96-511.
Sincerely,
/S/
John F. Stolz, Director PWP Project Directorate #6 Division of PWR Licensina-B
