The results of this study are contained in GE document GE-NE-770-06-0392 dated March 1992.This report is provided in Enclosure 4.9205200297

.May 13, 1992 GE has informed TVA that this report contains proprietary information.

GE requests that this report be withheld from public disclosure under 10 CFR 2.790.As required by 10 CFR 2.790(b), GE has prepared an application and affidavit requesting that the report be treated as proprietary information.

That application and affidavit are also contained in Enclosure 4.The necessity for the proposed TS change is increased by the observed failure history of Local Power Range Monitors (LPRMs)during Cycle 6 operation.

Projections of this failure rate indicate that the RBM may become inoperable later this cycle.Therefore, we request expedited approval of the proposed change and that it be made effective seven days after issuance.Sincerely, R.R.Baron Manager of Site Licensing In the absence of 0.J.Zeringue Vice President, Browns Ferry Operations Enclosure cc: See page 3 Subscribed and sworn to before me o this 13th day of~Ma 1992.Notary Public 9 h o t'I
