APPLICABILITY: OPERATIONAL CONDITIONS 1, 2 and 3.

ACTION:*

a. With the. safety and/or relief valve, function of pne 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 COLO 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 crie or mre safety /relie.f valves stuck open, close the stuck oper, safety / relief valve (s); if suppression pool average water temperaturo is 105*F or greater, plac4 the reactor muda switch in the Shutdown position.

c. With one or more safe $// relief valve acoustic monitors inoperable, restore the inoperable raonitor(s) to OPERABLE status within 7 days or be in at least HOT SHUTDCWN 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 />.

^The lift setting pressure shall correspond to ambient conditions of the

. valves at nominal operating temperatures and pressures.
