Dear Mr. Miller:

Rcquired Actions Based on Generic Implications of Salem ATWS Events at the Fort Calhoun Station Unit No. 1, Items 4.2.1 and 4.2.2 The Omaha Public Power District received your request for additional infor-mation dated October 4, 1984 (Reference 2). Forty copies of the District's response is the attached to this letter. This information is intended to supplement that provided in Reference 1, and is not intended to replace or supercede that information. Si erely, bk WG i R. L. Andrews Division Manager Nuclear Production RLA/dao cc: LeBoeuf, Lamt, Leiby & MacRae 1333 New Ilamshire Avenue, N.W. Washington, DC 20036 i Mr. E. G. Tourigny Mr. L. A.

'I Attachment A This attachment provides information regt.ested by letter from Mr. Miller to Mr. Andrews dated October 4,1984. The maintenance program for the Allen-Bradley Model 702 contactors consists of Maintenance Procedure MP-RPS-M-Contactor which is attached. The manufacturer's service bulletin is included lin the. maintenance procedure. Additionally, the contactors are tested monthly by using Surveillance Test ST-RPS-11. Tht. circuit breakers'(CB-AB and C3-CD),' Westinghouse molded case JA br eakers are included in the main-tenance' program and have a separate maintenance procedure, MP-RPS-Breaker which is attached. Again, the manufacturer's service bulletin is' included in the maintenance procedure. Specific responses to the requests' are presented below: Reouest 1.1 Provide the contactor and breaker manufacturers' specific ~ recommendations, including frequency, regarding periodic maintenance and surveillance. District

Response

For the Allen-Bradley contactor, the manufacturer recomrenda-tions for periodic maintenance are: a. Check for contamination b. Check operating mechanisms Check contacts for excessive wear or dirt c. d. Check terminals e. Check arc hoods and arc chutes f. Check coil for overheating Frequency specified is three to four months after initial installation and periodically thereafter as determined by operating conditions and experience. No surveillance is recommended by the manufacturer, however, surveillance is performed on the contactor eech month by utilizing ST-RPS-ll. For the Westinghouse JA circuit breakers, the manufacturer's recommendations for periodic maintenance are: a. Check terminal lugs for tightness b. Check trip unit for tightness Although the service bulletin states that contact c. cleaning is accomplished by the inherent wipino action of the contacts, conversations with the manufacturer representative indicates that by opening and closing the breaker "several times" under load will keep the contacts clean. No specific guidance is available from the manufacturer on frequency of preventive maintenance. Therefore, the District has elected to perform this preventive maintenance at refuel-ing frequency. ~ =

a failure of either the Allen-Bradley contactors or the Westing-i' . house circuit breakers. The only maintenance ever performed. on . the contactors or breakers has taken the form of preventive maintenance. Due to tha.locatioa:(control room) of the con-tactors and breakers, the environment is conducive to a long i . service-life of these components. Records are kept on main-t tenance activities at Fort Calhoun Station. During January, 1984, records were computerized with the CHAMPS system and prior l. to. January, 1984, records have been.kept, but are manual and'only b -cataloged in a computer program. In either case, maintenance records from initial startup are available.

J ' .

If analysis is ever necessary, initial analysis will be performed L -by the Plant Review Committee.-- Additional analysis, if required, will be performed by the Technical Services _ department. ~ The District believes that this; amplifying information, coupled with the informa- ~ tion in-our.
