REACTOR COOLANT SYSTEM 3/4.4.2 SAFETY / RELIEF VALVES LIMITING C0tOITION FOR OPERATION 3.4.2 The safety valve function of at least 9 of the following reactor coolant system safety / relief valves shall be OPERABLE with lift settings within 1 1% of the indicated pressures *.
4 Safety-relief valves a 1090 psig.
4 Safety-relief valves 01100 psig**.
3 Safety-relief valves 01110 psig**.
APPLICABILITY: CONDITIONS 1, 2 and 3.
ACTION:
- a. With the safety valve function of one of the above required safety / relief valves inoperable, be in at least HOT SHJTDOWN within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in COLD SHUTDOWN within the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
- b. With one or more safety / relief valves stuck open, place the reactor mode switch in the Shutdown position.
- c. With one or more safety / relief valve tail-pipe pressure switches inoperable and the associated safety / relief valve (s) otherwise indicated to be open, place the reactor mode switch in the Stotdown position.
SURVEILLANCE REQUIREMENTS 4.4.2 The tail-pipe pressure switch of each safety / relief valve shall be demonstrated OPERABLE by performance of:
- a. CHANNEL FUNCTIONAL TEST:
- 1. At least once per 31 days, except that all portions of the channel inside the primary containment may be excluded from the CHANNEL FUNCTIONAL TEST, and
- 2. At each scheduled outage of greater than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> during which entry is made into the primary containment, if not performed within the previous 31 days.
- b. CHANNEL CALIBRATION and verifying the setpoint to be 85 1 5 psig at l 1 east once per 18 months.
- The lift setting pressure shall correspond to ambient conditions of the valves at nominal operating temperature and pressure.
- Up to two inoperable valves may be replaced with spare OPERABLE valves with lower setpoints of 1090 or 1100 psig, respectively, until the next refueling outage.

'l ATTACt+ENT 2 NRC DOCKET 50-366 OPERATING LICENSE PPF-5 EDWIN I. HATCH NUCLEAR PLANT UNIT 2 PROPOSED CHANGE TO SAFETY RELIEF VALVE TAIL-PIPE PRESSURE SWITCH SETPOINT TECHNICAL SPECIFICATIONS Pursuant to 10 CFR 170.22, Georgia Power Company _ has evaluated the attached proposed amendment to Operating License tPF-5 and has determined-that:
- a. The proposed amen &ent does not require evaluation of a new Safety Analysis Report and rewrite _of the facility license;
- b. The proposed amendment does not require evaluation of several complex issues, involve ACRS review, or require an environmental irrpact statement;
- c. The proposed amendment does not involve a complex issue or more than one environmental or safety issue; j d. - The proposed amentent does involve a single safety issue, namely l that the setpoint for safety-relief valve pressure switches is i being changed..
- e. The proposed amendment is therefore a Class III amendment.
