ENCLOSURE REQUEST FOR INFORMATION NUCLEAR UITTLTTY OWNERS OF TDI DIESEL GENERATORS The NRR staff plans to issue a Safety Evaluation (SE) for each plant with TDI EDGs to close out the TDI engine reliability issues.
This final SE will 6e based, inpart, upon the Design Review/Ouality Revalidation (DR/QR) RepoFrY issued for each plant. However, during the preparation and subsequent submittal of the DR/OP reports a number of Part 21 notifications have been issued by TDI regarding potentially generic issues, which need to be addressed by each TDT owner utility.
To permit the staff to complete its review and prepare the final SE for each plant, utilities are requested to identify to NRR recent Part 21 reports issued by TDI (since April 1984) which concern problems potentially applicable to their plant, but which are not addressed in the DR/QR report for their plant. For each such Part 21 report, the utility should describe the actions it has taken to assess whether these potential problems exist at their plants, causes of these problems, short and lona term corrective actions to be taken, and implementation schedules.
With respect to recently observed problems with Clow Williams-Pacar check valves (Part 21 notifications from TDI dated March 12, March 14, April 4, and April 10, 1985), each utility is requested to address its actions relative to such valves located not just in the air start system, but also arfy such valves located in other EDG systems (e.g., jacket water and lube oil).
Tf corrective actions have not been implemented, the 4ustification for further delays shoild be provided.
Pending issuance of the final SE by the staff, the reauested information should also be provided on a similar schedule For any future Part 21 notifications from TDI.
