1 DtiCKET NO. 50-??ti l.ti INTPODIJCTION By anplication dated January 3, 1986, Niagara Mohawk Power Cornnration (the licensee) requested an amendment to Appendix A of Facility Operating License No.
DPR-63 for the Nine Nile Point Nuclear Station, I!nit No.
1.
The amendment would modify the Technical Specifications tTSl by adding an exolanatory phrase to clari~v the intention of the phrase "at all times" found in Table 3.6.14-1.
Notes for Table 3.6.]4-1 would be modified by adding footnote (i) which states that the intention of this phrase is to continuously monitor the Service JIater System effluent line by alternately sampling the reactor building and turbine buildino service water return lines for approximately 15 minute intervals.

0 Niagara mohawk proposes to install a
new monitor to samnle effluent ~rom the reactor building and turbine building service water return lines.
Taps will be installed in the reactor building and turhine building service water return lines and effluent pioed to the new monitor.
From the monitor, the effluent will he returned to the discharge tunnel.
A "stream selector" will be used to periodically (approximately every 15 minutes~
switch between the two effluent lines heing monitored.
The "stream selector" will alternately open one of the air operated valves and close the other air operated valve.
The monitor will alarm in the control room to alert the operator that action has to be taken to comply with Technical Specification 3.6.74 reouirements.
In addition, the computer point for the high radiation alarm will identify the effluent line being monitored by identi~ving the selector valve (air operated valve) which is open at the time.
In addition, the reactor building anIJ turbine building ser vice water return lines are nonsa<ety related.
Therefore, the piping, valves and monitor are nonsafety related.
In accordance with Regulatory Guide 1. 143, the piping valves and miscellaneous couplings will be designed, fabricatefJ, installed and inspected to the requirements of ANSI 831.1.
The proposed amendment incorporates an explanatory phrase clarifving the intent of the technical specification reouirement.
This phrase provides for the alternate sampling of the reactor building and turbine building service water return lines.
Interpreting the phrase to include monitorino conducted with approximate 15 minute time intervals on alternate return lines will provide the necessarv monitoring and additional diagnostic data required by the TS, and is therefore acceptable.
