SUBJECT:
SUMMARY
OF MAY 21, 1986 MEETING WITH REPRESENTATIVES OF NSSS OWNERS GROUPS AND NUMARC, TO DISCUSS PLANNED INDUSTRY ACTIONS IN RESPONSE TO THE CHECK VALVE AND WATER HAMMER EVENT AT SAN ON0FRE UNIT 1 ,
On May 21, 1986, the staff met in Bethesda, Maryland with representatives from INPO, and Westinghouse, Babcock & Wilcox, and Combustion Engineering NSSS Owners Groups. The purpose of the meeting was to discuss the proposed Owners Groups' plans regarding design, testing, and maintenance of safety-related check valves as a result of the November 1985 water hammer event at San Onofre Unit 1. Enclosure 1 is the list of attendees. A copy of the information provided by the staff and the Owners Groups is provided as Enclosure 2 and 3, respectively.
The industry's efforts in developing a check valve program will culminate in issuing two documents: a Significant Operating Event Report (S0ER) and an Application Guide. INP0 will be responsible for issuing the 50ER, which is currently scheduled to be issued by July 31, 1986. The SOER will include guidance on: alternate and enhanced inspection methods; wear and/or failure evaluation; enhanced maintenance procedures; testing of check valves including non-IWV valves; and verification of open and close operation.
Following issuance of the SOER, utilities would implement check valve main-tenance and test program changes based on the SOER guidance. The industry proposal limited the application of the 50ER to 5 PWR systems and 4 BWR systems based on failure rate data. It was agreed that each utility would also identify high risk check valves in each plant and include them in the program. Com-pletion of the implementation of the SOER was shown as July 29, 1988. We questioned the proposed schedule for implementation, as being too long. They agreed to look at that during final development. It was emphasized that the assigned dates are only estimates.

The AG will include information such as: appropriate use of the various types of check valves; physical location of check valves; flow consideration; check valve port sizing; etc. The AG is scheduled to be issued by April 30, 1987 with completion of the design reviews by the individual utilities by July 29, 1988. Implementa tion would follow the design reviews.
We were requested to provide any comments we have to the Owners Groups.
Mr. Merschoff, NRC, IE, discussed the NRC's ongoing efforts related to check valves (Enclosure 3). The six items that were discussed, and the NRC responsible contacts are listed below:

b ENCLOSURE 2 NRC Efforts Related to Check Valves f
- 1. San Onofre Water Hammer Event (IE Lead): As a result of this event, the '
staff has been directed to implement and coordinate actions necessary to assure the reliability of safety related-check valves. Including:
- a. The adequacy of check valve design for application in the feedwater ,
and other systems
- b. The adequacy of Inservice Testing (IST) Programs and procedures to detect degraded and failed valves
- c. The adequacy of check valve maintenance programs to assure operability
- 2. Generic Issue TMI II.E.6.1, In Situ Testing of Valves (NRR Lead): Study and make recommendations to change current in situ testing methods in order to provide assurance that valves (including check valves) will perform their safety-related functions under design basis as well as operating conditions.
- 3. Generic Issue 105, Interfacing System LOCA in LWRs (NRR Lead): Perform a risk analysis and a cost benefit analysis of leak testing reactor coolant boundary pressure isolation valves, including check valves. The results of this effort will be used to, among other things, support resolution of .
Generic Issue TMI II.E.6.1.
- 4. Generic Issue 93 Steam Binding of Auxiliary Feedwater Pumps (NRR Lead):
Determine an appropriate means to prevent steam leakage past check valves which could result in steam binding of the auxiliary feedwater pumps. This issue is being treated separately from the more general statement of the problem (Generic Issue TMI II.E.6.1.) because of its direct effect on plant safety.
- 5. Valve Performance Testing FIN B3050 (RES Lead): The purpose of this research is to evaluate the use of valve leakage as an indicator of valve degradation, to validate and improve as necessary the present technical >
specifications and ASME Code Section XI criteria for leak testing primary -
system isolation valves, and to evaluate advanced techniques for monitoring
- ' valve degradation. The results of this work will support resolution of Generic Issue TMI II.E.6.1.
- 6. Nuclear Plant Aging Research Program FIN 80828 (RES Lead): This research program involves, among other things, an attempt to identify the failure modes, causes, and mechanisms of check valve failures and to evaluate methods of surveillance, inspection, and monitoring which may be effective i in detecting degraded valves. The results of this work in concert with the Valve Performance Testing research described above will support resolution of Generic Issue TMI II.E.6.1.
