• RESPONSE SCHEDULE FOR GENERIC LETTER 84-15 Item 1 Reduction in Number of Cold Fast Start Surveillance Tests for Diesel Generators NRC Request la Licensees are requested to describe their current programs to avoid cold fast start surveillance testing or their intended actions to reduce cold fast start surveillance testing for diesel generators.

Response: To be provided by September 28, 1984 Item 2 Diesel Generator Reliability Data NRC Request 2a Licensees are requested to report the reliability of each diesel generator_ at their plant for its last 20 and 100 demands. This should include the number of failures in the last 20 and 100 vatid demands indicating the time history for these failures.

Response: To be provided by January 31, 1985 Justification for Extension: This request will require researching and reviewing approximately four years of selected periodic test procedures, Licensee Event Reports, operating procedures, operator logs, deviation reports, and 1maintenance request forms for seven emergency diesel generators. We will use July 31, 1984 as a point of reference for our review of diesel generator reliability data. All starts will have occurred. on or before this date, unless otherwise noted in subsequent correspondences. To the extent possible, data obtained subsequent to July 31, 1984 will be included in the data base.

NRC Request 2b Licensees are requested to indicate whether they maintain a record which itemizes the demands and failures experienced by each diesel generator unit, in the manner outlined in Regulatory Guide 1.108 position C.3.a, for each diesel generator unit. Licensees should

__ also indicate whether a yearly data report is maintained for each diesel generator's reliability.

• Response: To be provided by September 28, 1984

' e e Item 3 Diesel Generator Reliability NRC Request 3a Licensees are requested to describe their diesel generator reliability improvement program, if any, for attaining and maintaining a reliability goal. The program description should address the surveillance and testing the licensee performs to demonstrate the selected diesel generator reliability.

Response: To be provided by September 28, 1984 NRC Request 3b Licensees are requested to comment on and/or compare their program with the proposed performance specification and provide comments for staff consideration in finalizing surveillance testing requirements for diesel generators.

Response: To be provided by January 31, 1985 _

Justification for Extension: It will be necessary for us to assess the possible impact the proposed performance specification could have on the diesel generator and plant operation. The diesel generator reliability data will be *necessary in making this judgement.

Therefore, this response is dependent on the data that will be collected for Item 2a.
