SUMMARY
/ MINUTES OF THE APRIL 23, 1985 MEETING OF THE ACRS SUBCOMMITTEE ON RELIABILITY ASSURANCE (VALVES)
WASHINGTON, DC A meeting was held by the ACRS Subcommittee on Reliability Assurance on April 23, 1985. The purpose of the meeting was to continue the Sub-comrnittee's investigation of valve reliability. The Subcommittee dis-cussed programs and initiatives underway by the NRC and industry.
Notice of the meeting was published in the Federal Register on April 4, 1985 (Attachment A). Attachment B is a schedule of presentations.
Attachment C is a listing of meeting slides and handouts on file in the ACRS office. The meeting was entirely open to the public. Richard Major was the cognizant staff member for this meeting.
Participants NRC C. Michelson, Chairman J. Lombardo C. Wylie, Member A. Masciantonio D. Ward, Member G. Bagchi G. Reed, Member B. Weidenhamer J. Ebersole, Member J. Vora H. Jones, Consultant F. Cherny R. Major, Staff G. Millman G. Hammer Others 0. Rothberg J. Page B. P. Brooks, EPRI R. Bosnak R. Raczynski, DOE E. Brown

H. Sonderegger, ITT Grinnell Mr. A. Masciantonio, NRC discussed environmental qualification of ASCO solenoid valves. He noted the purpose of environmental qualification is to provide assurance that equipment will be able to perform required functions under all postulated environmental conditions. Mr. Ebersole was concerned that the postulated rupture of instrument lines and the environment created by this rupture is not considered in enough detail.

RELIABILITY ASSURANCE (VALVES) 2 April 23, 1985 Meeting The Staff explained it is the owner's responsibility to define the environment in which equipment will be operated.
The Staff explained that there is margin built into most pieces of equipment. When a valve becomes qualified for nuclear service, it is done on the basis of a particular model.
Qualification testing is usually done by the manufacturers. It is done because of contractual requirements and for marketing leverage. Test parameters are chosen to envelop the worst conditions expected. Various test programs and the results of the programs were reviewed.
Currently the NRC position on ASCO Solenoid Valves is that valves with VITON seals are not suitable for applications in which valves are required to shift position after exposures greater than 20 MegaRADS.
Valves with EPDM Seals are not acceptable if oil contamination in the air system exists.
Brian Sheron discussed Generic Issue 70, PORV and Block Valve Reliability. The generic item is designed to answer the question "Are PORVs and Block Valves good enough or should additional steps be taken to improve tham?" This item has been assigned a medium priority.
Traditionally, the PORV and its block valves are provided for plant operational flexibility and to limit the number of challenges on pressurizer safety valves. For overpressure protection of the RCS, the operation of PORVs has not explicitly been considered as a sa'fety related function. The valve operators and their electrical control systems are normally designed to non-safety related standards. The Staff intends to use PRA to determine the maximum risk reduction benefit and maximum dollar amount that could be reasonably spent on PORV and block valve improvements. The Commission wants a briefing on whether PORVs need to be safety grade in July 1985. (G.I. 70 does not consider PORVs in beyond-the-design-basis context such as feed and bleed or ATWS.
RELIABILITY ASSURANCE (VALVES) 3 April 23, 1985 Meeting These topics are a part of USI A-45.) The Staff offered to present a more detailed presentation in the future.
Joel Page of NRC discussed ASME Section XI, Inservice Testing of Valves.
All operating commercial BWRs and PWRs are currently required to have a valve inservice testing program in accordance with a specific edition and addenda of the ASME Code,Section XI. Valve testing requirements are based on the valve's safety function. Various test requirements for the different categories of valves were reviewed. Acceptance criteria were discussed.
Mr. Roger Lange and Mr. Gary Youngwirth (Wisconsin Public Service) discussed their valve experience at the Kewaunee Nuclear Plant. They explained Kewaunee Nuclear Plant has valves from over 100 different manufacturers. There is a preventative maintenance program which schedules periodic testing, lubrication, inspection and repacking of many valves in the plant. During refueling outages, valves are inspected and repacked if it is determined that the amount of packing adjustment left would not be sufficient to last until the next outage.
During a typical outage, 200 valves will be repacked in addition to the valves repaired or replaced. It is felt that with the preventative maintenance and valve repacking program, valve problems have been kept to a minimum. The valve program's payoff is increased plant availability.
The largest problems with valves at Kewaunee are packing leaks, body to bonnet leaks, and leaking through the seat. Kewaunee is also facing problems in the area of obtaining spare parts or equipment replacements as manufacturers go out of business or get out of the nuclear business.
Mr. Reed commented on the MOVATS system for valve testing. If proven effective, it could, he believed, be used to reduce the amount of inservice testing of motor operators. The MOVATS system is not in use at Kewaunee plant.
RELIABILITY ASSURANCE (VALVES) 4 April 23, 1985 Meeting Boyd Brooks of EPRI discussed valve-related research and development conducted by the Electric Power Research Institute. He went through a list of relevant publications and discussed ongoing resaarch. He noted that EPRI is evaluating the M0 VATS device and expect; to publish an interim report in the next quarter. A final report is axpected by 1986.
Other key valve issues being addressed are: valve motor operator improvements and valve stem packing improvements.
Mr. W. Knecht of Anchor / Darling Valve Company discussed valve experience from a manufacturer's point of view. He noted his company has been making nuclear grade valves since 1956. Although valves are specified for nuclear service, he felt it is not a particularly severe type of service for the valves (as compared to super critical fossile or process applications). It was his experience that it was a much more severe test of a valve to close against break blowdown forces than to open against a static force. Mr. Knecht said that their experience is reported to customers directly, not to INP0 or to NRC. To get information to the NRC or INP0 the utility must act as the go-between.
Mr. H. Sonderegger, ITT-Grinell, discussed activities of the ASME Subcommittee on Qualification of Nuclear Valve Assemblies. The areas this group is working on include: "Self Operated and Power Operated Safety Related Valves Functional Specification Standard" and " Functional Qualification Requirements for Self Operated Check Valve Assemblies for Nuclear Power Plants." Other areas also under investigation are:
" Functional Qualification Requirements for Active Pressure Relief Valves for Nuclear Power Plants" and " Functional Qualification Requirements for Power Operated Active Valve Assemblies for Nuclear Power Plants."
The Subcommittee decided it wished to have another meeting. Items to be discussed include a risk perspective on valve performance and how well are PRAs really modeling valve performance. The Subcommittee will also look at valves in the context of overall plant safety and valves'
.o RELIABILITY ASSURANCE (VALVES) 5 April 23, 1985 Meeting contribution to plant safety. A presentation by Limitorque would also be desirable. Mr. Michelson will make an interim report on the Subcommittee's progress to the full Committee in June.
