REACTOR COOLANT SYSTEM SAFETY VALVES LIMITING CONDITION FOR OPERATION 3.4.2.1 A minimum of one pressurizer code safety valve shall be OPERABLE with a lift setting of 2500 PSIA i 1%.

APPLICABIllTY: MODES 4 and 5.

ACTION:

With no pressurizer code safety valve OPERABLE, immediately suspend all operations involving positive reactivity changes and place an OPERABLE shutdown cooling loop into operation.

13.4.2.2 All pressurizer code safety valves shall be OPERABLE with a lift setting of 2500 PSIA i 1%.

APPLICABillTY: MODES 1, 2 and 3.

ACTION:

With one pressurizer code safety valve inoperable, either restore the

-ino>erable valve to OPERABLE status within 15 minutes or be in HOT SHUTDOWN wit 1in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

SURVEILLANCE REQUIREMENTS 4.4.2 Each pressurizer code safety valve shall be demonstrated OPERABLE with a lift setting of 2500 PSIA i 1%, in accordance with Specification 4.0.5. l MILLSTONE - UNIT-2 3/4 4-2

a '

REACTOR COOLANT SYSTEM SURVEILLANCE REQUIREMENT 4.4.9.3.1 Each PORV shall be demonstrated OPERABLE by:

a. Performance of a CHANNEL FUNCTIONAL TEST on the PORV actuation channel, but excluding valve operation, within 31 days prior to entering a condition in which the PORY is required OPERABLE and at least once per 31 days thereafter when the PORV is required OPERABLE.

b. Performance of a CHANNEL CALIBRATION on the PORY actuation channel at least once per 18 months.

'c. ' Verifying the PORV' isolation valve is open at least once per 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> when the PORV is being used for overpressure protection.

d. Testing in accordance with the inservice test requirements of Specification 4.0.5.

4.4.9.3.2 The RCS vent (s) shall be verified to be open at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />

• when the vent (s) is being used for overpressure protection.

• Except when the vent pathway is provided with a valve which is locked, sealed, or otherwise secured in the open position, then verify these valves open at least once per 31 days.

s SAFETY VALVES LIMITING CONDI' TION FOR OPERATION 3.7.1.1 All main steam line code safety ' valves shall _be OPERABLE.-

APPLICABILITY: MODES 1, 2, and 3.-

ACTION:

a. With both' reactor coolant loops and associated steam generators in operation ~ and with' one or more main steam line - code safety _ valves inoperable, operation in MODES 1, 2, and 3 may. proceed provided, that within 4thours, either the inoperable _ valve is restored to OPERABLE status ~ or the Power Level-High trip setpoint is reduced

.per Table 3.7-1; otherwise, be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTOOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />,
