'! 4.4.6.2.1 Reactor Coolant System leakages shall be demonstratad to be within each of the above limits by:

a. Monitoring the contain=ent atmosphere particulate radioactivity

)

monitor at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

b. Monitoring the containment sumo inventory and discharge at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

c. Measurement of the CCNTROLLED LEAKAGE to the reactor coolant pumo seals when the Reactor Coolant System pressure is 2235 20 psig at least once per 31 days with the modulating valve fully open. The provisions of Specification 4.0.4 are not applicamle for entry into MODE 4.

d. Performance of a Reactor Coolan System water inventory balance at least once per 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

e. Monitoring the reactor head flange leakoff temoerature at least onca per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

4. 4. 5. 2. 2 Each Reactor Coolant System Pressure Isolation Valve specified in Table 3.4-1 shall be de=anstrated 07/.> ASLE pursuant to Specification 4.0.5, except tnat in lieu of any leakage testing required by Soecification 4.0.5, eaca valve shall be demonstrated OPERABLE oy verifying leaAage to be witnin its limit:

I

a. At least once per 18 months.

2

b. Prior to entering MOCE sr whenever the olant has been in COLD SHUTOC'aN for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or more and if leakage testing has not been performec in the previous 9 months.

c. Prior to returning the valve to service following maintenance, I repair or replacement work on tne valve.

d. Within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> following valve actuation due to automatic or-manual action or flow through the valve.
