By letter dated July 23, 1992, the Tennessee Valley Authority (TVA) submitted a license amendment request (TS 316) to revise the Browns Ferry Nuclear Plant (BFN) Technical Specifications (TS).
This amendment request would make the BFN TS consistent with TVA's proposed analog-to-digital upgrade of the Reactor Building Ventilation Radiation Monitoring System (RBVRH).
After reviewing TVA's submittal, the staff has determined that some additional information will be necessary in order for the staff to complete its safety evaluation.
Therefore, TVA is hereby requested to provide the additional information as specified in the enclosed list.
TVA should respond to this request for additional information (RAI) as soon as possible, but no later than thirty days from the date of this RAI.
This requirement(s) affects 9 or fewer respondents and, therefore, is not "subject to Office of Management and Budget review under P.L.96-511.
If you have any questions regarding the content of this RAI, please contact Thierry H. Ross, NRC Project Manager at (301) 504-1474, Sincerely, FredePick J.
