INSTRUMENTATION POST-ACCIDENT MONITORING INSTRUMENTATION LIMITING CONDITION FOR OPERATION 3.3.6.4 The post-accident monitoring instrumentation channels shown in Table 3.3.6.4-1 shall be OPERABLE.
APPLICABILITY _: CONDITIONS 1 and 2.
ACTION:
- a. With fewer than the Minimum Channels Operable (as required by Table 3.3.6.4-1), either restore the inoperable channel (s) to OPERABLE status such that the Minimum Channels Operable criteria in Table 3.3.6.4-1 is met within 30 days or be in at least HOT SHUTD0k'N within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
b.
The provisions of specification 3.0.4 are not applicable.
SURVEILLANCE REQUIREMENTS 4.3.6.4 Each of the above required post-accident monitoring instrumen-tation channels shall be demonstrated OPERABLE by perfomance of the CHANNEL CHECK and CHANNEL CALIBRATION operations at the frequencies shown in Table 4.3.6.4-1.

- If either the primary or secondary indication is inoperable, the torus temperature will be monitored at least once per shift to observe any unexplained temperature increases which might be indicative of an open SRV. With both the primary and secondary monitoring channels of two or more SRVs inoperable either restore sufficient inoperable channels such that no more than one SRV has both primary and secondary channels inoperable 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 />.
- Each instrument constitutes an independent operable channel.
