SUBJECT:

SCHEDULE FOR RESOLVING AND COMPLETING GENERIC ISSUE NO. 91 - MAIN CRANKSHAFT FAILURES IN TRANSAMERICA DELAVAL EMERGENCY DIESEL GENERATORS The technical resolution for Generic Issue No. 91, " Main Crankshaft Failures in Transamerica Delaval Emergency Diesel Generators" has been identified in the staff SER on the TDI Diesel Generator Owners' Group Program Plan as explained in the enclosed prioritization evaluation. However, the generic lessons learned may warrant changes to the SRP, STS or a Regulatory Guide.

A schedule for making these changes (or deciding that none is necessary) should be developed and monitored.

In accordance with NRR Office Letter No. 40, " Management of Proposed Generic Issues," the resolution of this issue will be monitored by the Generic Issue Management Control System (GIMCS). The information needed for this system is indicated on the enclosed GIMCS information sheet. Your schedule for resolving and completing this generic issue should be commensurate with the priority nature of the work and consistent with the NRR Operating Plan.

Normally, as stated in the Office Letter, the information needed should be provided within six weeks.

The attached prioritization evaluation will be incorporated into NUREG-0933, "Prioritization of Generic Safety Issues," and is being sent to other NRC offices, the ACRS, and the PDR for comments on the technical accuracy and completeness of the prioritization evaluation. Any changes as a result of comments will be coordinated with you. However, the schedule for the resolution of this issue should not be delayed to wait for these comments ~.

The information requested should be sent to the Safety Program Evaluation Branch, DST. Should you have any questions pertaining to the contents of this memorandum, please contact Louis Riani (24563).
