!
Unit 1 Technical Specification (TS) 3;3.3.6. action (a) requires that with the number of operable accident monitoring channels less than the total number of channels shown in Table 3.3-10, either restore the inoperable channel ~ 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 />.
Table 3.3-10 requires a total number of two channels of Reactor Vessel Coolant Level Monitoring (RVLIS) equipment;
[
To verify oper, ability, TS 4.3.3.6 requires the monthly performance of a-
channel check of the RVLIS system.
