Dear Mr. Grier:
O 1
S SUPPLEMENTAL RESPONSE NO. 2 TO NRC IE BULLETIN NO. 80-24 PREVENTION OF DAMAGE DUE TO WATER LEAKAGE INSIDE CONTAINMENT (OCTOBER 17, 1980 INDIAN POINT 2 EVENT)
SALEM GENERATING STATION UNITS NO. 1 AND 2 DOCKET NOS. 50-272 AND 50-311 On January 2, 1981, we indicated in our response to thd subject Bulletin Item No. 3.h. that a radiation detector is installed in the service water outlet piping of each containment fan coil.
We also indicated that upon initiation of a high radiation level, a bezel alarm is actuated and the coil is isolated by procedure.
After further review of this response, it became evident these statements required clarification and correction.
An in-line radiation detector is installed in each of the service water outlet pipes of each 'atainment fan coil in Unit 1.
On Unit No. 2 three off-line radiation detectors are used to sample the service water discharge of the five con-tainment fan coil units.
The sample lines are equipped with isolation valves.
As mentioned above, a bezel al. arm will be actuated in the Unit 1 Control Room upon detection of high radiacion in the service water outlet piping for each of its fan coil units.
For Unit 2 an RMS alarm will be actuated in the Unit 2 Contrni Room on the overhead alarm panel.
The RMS CRT and printer will indicate high radiation detected in the fan cooler outlet piping.

- Mr. Boyce H. Grier, Director U.S. Nuclear Regulatory Commission 6/2/81 If the alarms are actuated for either unit, the operator does not have a specific procedure to immediately isolate the fan cooler service water supplies.
Emergency Instruction I-4.16, Radiation Incident, requires the operator'to investigate. the cause of the alarm.
The final decision to isolate the coils is based upon plant conditionr, analyses and indications.
If you have any further questions, we will be pleased to discuss them with you.
Sincerely,
?,. A.
