Dear Mr. O'Reilly:
Enclosed is our response to J. T. Sutherland's December 7, 1978, letter, RII:LLJ 50-259/78-30, 50-260/78-33, 50-296/78-31, concerning an activity at Browns Ferry Nuclear Plant which appeared to be in noncompliance with NRC requirements.
We have reviewed the above inspection report and find no proprietary information in it.
Very truly yours,

1 ENCLOSURE F.sponse to NRC Inspection Report RII:LLI 50-259/78-30, 50-260/78-33, 50-296/78-31 Finding Technical Specification 3.1 and Table 3.1.A required that the trip level setting on the rain steam line high radiation moni. tors be set at less than or equal to 3 times
- i e normal full power background.
Contrary to the above, on November 14, 1978, an NRC inspector determined that the irip !.evel Settings for channels B, C and D of the Unit 2 main r, team line high
'adiation monitors were respectively 3.4, 5.3 and 3.4 times the normal full power Lackground.
i tesponse Corrective Stens Taken And Results Achieved ihr background radiation level was measured in the unit 2 nain steam line tunnel and the 'aain steam line high radiation monitors calibrated based on the measured value.
i"e error in the setpoint was due to a lower radiation level in the main steam tunne
.ter the refueling.
arrective Steps Taken To Avoid Further Noncomp]Iance t
i:.e calibration of the main steam line radiation monitors based on full load Mckground radiation will be performed as part. of the refuel retest program.
i!:te Ful1 Compliance Was Achieved 11 compliance was achieved on unit 2 on November 14, 1978; and revision to the refuel retest progran was made on December 8, 1978.
