REACTOR C00LAtlT SYSTEM 3/4.4.2 SAFETY / RELIEF VALVES LIMITING CONDITIOfi FOR OPERATION 3.4.2 The safety valve function of all reactor coolant system safety /

relief valves shall +be OPERABLE with lift settings within i 1% of the following values.*

l 4 Safety-relief valves @ 1105 psig.

4 Safety-relief valves @ 1115 psig.

3 Safety-relief valves @ 1125 psig.

APPLICABILITY: CONDITIONS 1, 2 and 3.

ACTION:

a. With the safety valve function of one safety / relief valve inoperable, restore the inoperable saf4.ty valve function of the valve to OPERABLE status within 31 days or be in at least HOT SHUTDOWN within the followingwithin 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 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

b.

With the safety valve function of two safety / relief valves inoperable, restore the inoperable safety valve function of at least one of the valves to OPERABLE status within 7 days or be in at least HOT SHUTDOWN SHUTDOWN within within the following 24 the next 12 hears and in COLD hours.

c.

With the safety valve function of more than two safety / relief valves inoperable, be in at least h?T 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 />.

SURVEILLANCE REOUIREMENTS 4.4.2 The safety valve function of each of the above required safety /

relief valves shall be demonstrated OPERABLE by verifying that the bellows on the safety / relief valves have integrity, by instrrmentation indication, at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

• The lift setting pressure shall correspond to ambient conditions of the valves at nominal operating temperature and pressure.

+From Spring,1980 until the maintenance outage in Sept. , 1980, the safety-relief valve lift settings shall be within i 1% of the following values:

2 Safety-relief valves @ 1095 psig 3 Safety-relief valves @ 1105 psig 3 Safety-relief valves @ 1115 paig 3 Safety-relief valves @ 1125 psig The lift settings shall be arranged such that each safety-relief valve pair has a minimum nominal lift setting differential of 20 psi.
