safety/relief valves 9 1205 psig +3%/-3X APPLICABILITY:
OPERATIONAL CONDITIONS 1, 2, and 3.
ACTION:
a.
Mith the safety valve function of one or more of the above required safety/relief valves inoperable, be in at least HOT SHUTDOWN 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.
Mith one or more safety/relief valves stuck open, provided that suppression pool average water temperature is less than 90'F, close the stuck open safety/relief v'alve(s); if unable to close the open valve(s) within 2 minutes or if suppression pool average water tempera-ture is 110'F or greater, place the reactor mode switch in the Shut-down position.

With one Safety/Relief Valve Position Indicator inoperable, for one or more SRVs, operation may continue until the next outage of sufficient duration to effect repairs, provided once per 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />s:
1) the remaining OPERABLE position indicator for the affected SRV(s) i's verified to indicate the SRV(s) are closed, and 2) the suppression pool temperature is verified to indicate the SRV(s) are closed.
With two Safety/Relief Valve Position Indicators inoperable for one or more SRVs, perform the requirements of c.2 above.
Restore at least one of the inoperable channel(s) for each SRV to OPERABLE status within 7 days or be in at least HOT SHUTDOWN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

INSERT ACTION 82-a.
With the number of OPERABLE Safety/Rel,ief Valve Position Indicators less than the Required Number of Channels shown in Table 3.3.7.5-1 for one or more
- SRYs, operation may continue until the next outage of sufficient duration to effect r'epairs, provided once per 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />s:
1) the remaining OPERABLE position indicator for the affected SRV(s) is verified to indicate the SRV(s) are closed, and 2) the suppression pool temperature is verified to indicate the SRV(s) are closed.
b.
With the number of OPERABLE Safety/RelieF Valve Position Indicators less than the Minimum Channels OPERABLE shown in Table 3.3.7.5-1 for one or more b
SRVs, perform the requirements of a.2 above.
Restore the inopera le channel(s) to OPERABI E status within 7
days or be in at least HOT SHUTDOWN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
