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.
