R. P. Zirfpfman, Chief Reactor Pfejects Branch Meeting Sumary: A Management Meeting was held on November 14, 1988 at the licensee's facility to discuss the licensee's operational performance since restart in March,1988, and to discuss SMUD's progress regarding pre-restart comitments to perform various activities after restart. These comitments included efforts in the areas of engineering, procurement, the performance improvement program, maintenance, and radioactive effluent systems. The conclusion reached was that SMUD's operational performance since restart had been good. SMUD's progress on post-restart comitments was unclear, particularly with respect to design basis reconstruction, and perfonnance improvement program problem resolution.

The NRC Regional Administrator stated that the purpose of the meeting was to review current issues with SMUD's operation of Rancho Seco. The meeting fcllowed the agenda in the "Status Update" viewgraf attached, with questions and discussion a:; they arose during 5 3's presentation. A brief presentation of the licensee's interim c od long term plan:, to reduce the volume and activity of secondary plant effluents was appended to the presentation at the NRC's request. Discussion of recent feedwater system history was not conducted due to time limitations, but will be discussed at a subsequent meetin b. Specific Issues Power Ascension Program Mr. Firlit gave a progress report on Rancho Seco's activities since restart, noting that SMUD's plans for completing the final power escalation from 92% to 100% were still being developed. Mr. Martin cautioned SMUD to fully discuss their intent with the NRC before changing the previously approved power ascensioa progra . Emergency Preparedness Mr. Firlit noted that the 1988 emergency exercise had been

"highly seccessful." Mr. Martin agreed that SMUD had imprnved substantially in this area in the last five years, but emphasized that emergency exercise results were highly sensitive to the training of the specific personnel involve He stressed that this is an area which, as at most plants, requires continuous management attention to ensure good results, including the maintenance of a strong working relationship with offsite authoritie . Quality Assurance Effectiveness Mr. Firlit discussed the increased numbers of audits conducted by the Quality department, and the improved results of the latest INP0 evaluation just completed. He noted that further l evaluations by the Nuclear Performance Comittee in December l 1988, and May 1989, were planned, as well as the completion of I twenty mot e system evaluations under the Expanded Augmented

'

System Review and Test Program (EASTRP) progra Mr. Miller noted that recent NRC inspection results indicated some reluctance by SMUD personnel to formally identify nonconformances due to a perception by some personnel that SMUD management was discouraging their use. A general I

discussion ensued, from which it was concluded that SMUD recognized that further management attention was necessary to ensure all SMUD personnel were encouraged to identify and document nonconforming conditions, rather than unintentionally discourage piant staff from doing s _

.

. 3 o e e Mr. Martin emphasized that SMUD's biggest challenges were to be highly self-critical, and to have the capacity to learn from mistakes. He noted that SMUD had the programs in place to meet these challenges, but the important task remaining was for management to ensure that everyone instinctively used these existing programs effectivel . Performance Improvement Program Comitments ("QCI-12 Process")

Mr. Shetler reviewed the changes since restart in SMUD's programs to find and remedy all significant problems at Rancho Seco. He then presented the current status of open problem The licensee recognized that follow-up of the non-hardware problems had slackened to the extent that the status and schedule for completion was not completely know Mr. Kirsch observed that during tne January 1987, SMUD presentation of this program to the NRC Commission, SMUD had stated that nesr term (also known as Priority 2) items would be completed during the next refueling outage. Mr. Shetler pointed out that in April 1987, and again since restart, SMUD had made significant changes to this program. However, SMUD agreed that the system for prioritizing corrective action of problems changed after restart rather than befor Mr. Martin stressed that the approval to restart Rancho Seco had not only been based on problems SMUD had corrected, but also on problems they agreed to correct after restart. He further emphasized that, until changed by mutual agreement of the NRC and SMUD, the connitments to resolve the near term (Priority 2) problems by the end of the next refueling outage remained in force. He noted, however, that some new issues could have developed since restart which could properly receive priority for completion before all of the Priority 2 problem He concluded by stressing that any diminishment of SMUD's level of effort on known existing problems, or change in the prioritization of problem resolution without agreement of the NRC was not acceptabl Mr. Boggs and Mr. Martin then agreed that a technical meeting in the near future, to clearly define SMUD's connitments in this area, is essential. Mr. Boggs affirmed that SMUD would meet its comitments to the NRC, even if additional resources, which had not been previously budgeted, were require . Maintenance Mr. Brock made a presen* Jtion of the nature and trend of SMUD's maintenance backlog since restart. He stated that SMUD's goal was to reduce the backlog to 600 items by mid-198 The principal reason offered for the backlog was the large number of discretionary preventive maintenance items, most of which were originated and done for the first time after restart. .

In this area, Mr. Martin observed that the number of control room annunciators which were unnecessarily alarming appeared to be excessive. Mr. Firlit responded that SMUD's goal was to reduce the number of such alarms to zer In response to an NRC question, Mr Brock stated that SMUD's intention was to replace or repair all valves in the plant which had been repaired by injection of a temporary sealan This effort is contingent on plant conditions and spare parts availability. He also noted that this effort included a search of equipment history records to determine which valves have been repaired with this techniqu . Engineering Action Plan Mr. Ferguson presented SMUD's plans for developing a comprehensive computer database configuration management system for Rancho Seco by 1991. Messrs. Miller and Crews asked when the first plant system would be incorporated into this database such that a complete design basis description l of the plant system existed. SMUD could not provide a i schedule for this milestone.

l Mr. Martin expressed concern that some of SMUD's comitments I as expressed in the Engineering Action Plan approved prior l to restart appeared to have changed significantly from that which had been agreed to prior to restart. SMUD representatives

'

were not prepared to address these questions directly. It was agreed that a meeting in the near future to clarify SMUD's comitments would be appropriat . Procurement Mr. Rediken presented the status of comitments made in the procurement program. There was a question between SMUD representatives regarding whether the environmentally qualified equipment parts evaluation had been completed by June 30, 1988 as comitted. This item will be discucsed further in the resident inspection report which includes this perio . Radioactive Effluent System Plans Mr. Melancon presented a description of the short and long tenn modifications SMUD intends to install to minimize waste water volume and activity from Rancho Seco. The short term modifications include: Recirculating the auxiliary feedwater pump bypass flow to the condensate storage tank rather than draining it to the hotwell as presently configured; u

. ~ Recirculating selected secondary sample lines to the hotwells rather than to secondary sumps; Installing a demineralizar and filter in the condensate polisher sluice water effluent line; and Installing a high capacity portable demineralizer between the regenerative holdup tanks and the retention basin These modifications are expected to improve normal operating efficiency and increase capacity factor. In addition, a major upgrade of the tank farm and a new waste water treatment facility are planned in the near future. Mr. Martin emphasi. ed that previous SMUD plans in the past few years have not progressed very far, and stronger SMUD comitment to folicuing through on the plans made is importan c. Conclusion Mr. Boggs sumarized his view that SMUD should clarify further with the NRC whether it is doing what the NRC expects in the areas of plant improvements, the QCl-12 process, and the Engineering Action Plan. He stressed that the CE', Nuclear, Mr. Firlit, has SMUD's

-

total support for meeting the NRC's-expectation Mr. Martin stated that Rancho Seco has clearly operated very well since restart, but the completion of the Engineering Action Plan and the near term Performance Improvement Program items is not clear, and further discussion between SMUD and the NRC to clarify and status existing commitments in these ares is necessar _ _ . . - . _- . . _ _ _ _ . . . _ _ . - _ .
