d' May 14, 1986 y $9 - 3d 1 LICENSEE - Sacramento Municipal Utility District FACILITY - Rancho Seco Nuclear Generating Station SUBJECT - Summary of Meeting on April 18, 1986 with Sacramento Municipal Utility District (SMUD)
On April 18, 1986, the Sacramento Municipal Utility District (SMUD) met with the NRC staff in Bethesda to review SMUD's proposed plant performance and management improvement program for the Rancho Seco plant. This presentation was a follow-up to the meeting held between SMUD and senior NRC management on March 24-25, 1986 where SMUD was requested to take a broader perspective regarding the issues affecting the safe and reliable operation of the Rancho Seco plant beyond the narrow focus of responding to the December 26, 1985 transient. Enclosure 1 is a list of the attendees. Enclosure 2 is a copy of the material presented by SMUD at the meeting.
SMUD presented an outline of its program to improve its management organization, systems and procedures, communications, and plant performance.
The organization is being restructured to include six departments vs the present three, with new management personnel being brought in from outside SMUD. Management systems and procedures, functional interfaces and information flow (dissemination and feedback) will be evaluated. From the evaluation, recommendation for change or improvement will be made for implementation to improve overall management performance. The plan has been reviewed and approved by management.
The performance indicators SMUD will use to judge management performance are (1) plant availability, (2) forced outage rate, (3) reactor trips, (4) NRC violation, (5) NRC SALP ratings, (6) INp0 findings, (7) low level solid radio-active waste, (8) personnel radiation exposure and (9) lost time accidents. Their near term goal is to have a better than 60% plant availability, no greater than 10% forced outage rate and less than 3 reactor trips per year.
The licensee has organized a performance analysis group to develop a program beyond that currently established to respond to the December 26, 1986 transient to improve the overall plant performance of Rancho Seco. The program will incorporate a short term element requiring resolution prior to restart and a longer term element. The licensee will do a deterministic failure consequences analysis primarily on motive power systems to determine whether system failures could (1) cause a reactor trip, (2) challenge safety systems and/or impact the ability to stay in the " Post-Trip Window" (predicted reactor coolant pressure and temperature and steam outlet temperature and pressure). Equipment and or system whose failures will result in one or more on these conditions will be evaluated for modificatinn, enhanced procedures, enhanced training and possible testing. In addition, SMUD stated they will conduct interviews with their staff to obtain issues and concerns regarding plant design and operations. They will also factor into their restart program precursor documents referenced in the NUREG-1195 report (IIT Report) and such things as I&E Bulletins and Notices, LER's, Trip Reports, etc.

The licensee indicated that some of the items will be implemented in parallel with the analysis and evaluation portion of the program. They expect the analysis and evaluation part of the program will be completed in June to support-issuance of the Rancho Seco startup report for NRC review early in July 1986.
The NRC staff had the following major comments:
- 1. The staff suggested that, in addition to low level solid radioactive waste, radioactive liquid waste (releases) should be considered as a performance indicator.
- 2. The startup program should be comprehensive enough to provide reasonable assurance that when restarted the plant can be safely and reliably operated. It is not necessary that the program be like the Davis-Besse program. However, they should be prepared to justify their program when it is compared to what appears to be a more comprehensive test program being conducted at Davis-Besse.
- 3. The staff questioned whether the deterministic failure consequences analysis program limited to only the motive systems will result in a sufficiently comprehensive start-up program to demonstrate reasonable assurance of reliable and safe operation.
- 4. The staff also noted that the test program described appeared rather limited. l
. In conclusion, SMUD indicated that it will consider all of the staff's comments made during the meeting in developing its restart program and report.
