{ Docket No. 50-461 APPLICANT: Illinois Power Company FACILITY: Clinton Power Company
SUBJECT:
SUMl'ARY OF FOLLOW UP MEETING WITH ILLIN0IS PCWER COMPANY RELATED TO THE PuliP AND VALVE OPERABILITY RECOVERY PROGRAM A n'eeting with Illinois Pov.er Ccmpany (IP) and Sargent and Lundy (S&L) was held with the NRC staff and its consultant BNL on October 21, 1985, in Bethesda, Maryland. The purpose of the meeting was to demonstrate the following: That the IP Pump and Valve Operability Program is in ccepliance with NRC regulatory guidance. The program is being conducted properly. To ensure that there was a clear understanding of what was required by IP to successfully complete the Pump and Valve Operability (PVORT) audit. This meeting was held as a follow up to a meeting held on September 26, 1985, to provide asturance to the staff of the acceptability of the IP recovery program. Plans for a recovery program and re-audit were initiated because the results of the staff PV0RT audit held the week of August 26, 1985 were deternined to be unacceptable. A list of the teeting attendee's is contained in Enclosure 1 and copies of VU-graphs used by IP and S&L during their presentation is contained in Enclosure 2. Key points cade by IP during their presentation were: . The IP Pump and Valve Operability Program meets the NRC regulatory requirements. Stone & Webster was engaged to conduct an audit of the i Sargent & Lurdy program and found it adequate. All pumps or valves in the program were covered by tests or analysis or both. A large representative sample of valves was tested and cortparisons of the results of the analyses with the test results den'onstrated that the analyses were conservative. The method of determining operability was demonstrated for one of the suction isolation valves in the Reactor Core Isolation (RCIC) system.
IP wanted a clear understanding of what was expected for the hovember PVORT audit. IP wanted to receive staff confirmation that the approach for conducting the Pump and Valve Operability Program was acceptable. At the end of the meeting the staff concluded: The staff had no major concerns related to the IP Pbn.p ar.d Valve Operability Program based on the information presented during the re-audit meeting. The staff will proceed with a re-audit of the IP PVORT. The week of November 18, 1985 for the audit was mutually agreed upon. All packages to be reviewed by the staff prior to the audit trust be submitted to the staff by November 8, 1985. The responses to the 30 audit items from the initial audit should be submitted by November 4,1985. The re-audit components would be selected from those remaining frcm the August audit plus ten new components which were provided to IP cn October 25, 1985. In addition two " surprise" components will be given to IP a few days prior to the audit. B. Sit. gel, Project Manager Licensing Branch fio. 2 Division of Licensing

f l IF wanted a clear understanding of what was expected for the tiovar,ber PVORT audit. IP wanted to receive staff confirmation that the approach for conducting the Pump and Valve Operability Program was acceptable. At the end of the meeting the steff concluded: 1he staff had no major concerns related to the IP Purap and Valve Operability Prograra based on the information pc. sented duiing the re-audit meeting. The staff will proceed with a re-audit of the IP PVORT. The week of fiovember 18, 1985 for the audit was nutually agreed upon.
~
All packages to be reviewed by the staff prior to the audit nust be sutnitted to the staff by November 8, 1565. The responses to the 30 audit items from the initial audit should be subnitted by November 4, 1985. The re-aucit components would be selected from those remaining fron the Auged audit plus ten ncw ccraponents which were provided to IP on Octob 25, 19F5. In addition two " surprise" corponents will be given to IP a few days prior to the audit. Original Signett by B. Siegel, Project Manager Licensing Branch No. 2 Division of Licensing
