CONTROLLED COPY REACTOR COOLANT SYSTEM 3/4.4.2 SAFETY/RELIEF YALYES LIMITING CONDITION FOR OPERATION 3.4.2 The safety valve function of at least 12 of the following reactor coolant system safety/relief valves shall be OPERABLE with the specified code safety valve function liftsettings:"

2 safety/relief valves I 1150 psig +3%/-3X 4

safety/relief valves I 1175 psig +lX/-3X 4

safety/relief valves I 1185 psig +EX/-3X 4

safety/relief valves I 1195 psig +3%/-3X 4

safety/relief valves I 1205 psig +1K/-3X APPLICABILITY:

OPERATIONAL CONDITIONS 1, 2, and 3.

ACTION:

a.

Mith the safety valve tunction 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.

c.

Mith one or more safety/relief valve acoustic monitors inoperable, restore the inoperable monitor(s) 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 /> and in COLD SHUTDOWN within the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.+ + +

SURYEILLANCE RE UIREMENTS 4.4.2 The acoustic monitor for each safety/relief valve shall be demonstrated OPERABLE by performance of a:

a.

CHANNEL CHECK at least once per 31 days, and a

b.

CHANNEL CALIBRATION at least once per 18 months.""

"The lift setting pressure shall correspond to ambient conditions nf the valves at nominal operating temperatures and pressures.

""The provisions of Specification 4.0.4 are not applicable provided the survei.llance is performed within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after reactor steam pressure is adequate to perform the test.
