STEAM AND FEEDWATER RUPTURE CONTROL SYSTEM INSTRUMENTATION LIMITING CONDITION Foi OPERATION 3.3.2.2 The Steam and Feeowater Rupture Control System ($FRCS) instrumen-tation channels shown in Table 3.3-11 shall be OPERABLE with their trip setpoints set consistent *:N the values shown in the Trip Setpoint column of Table 3.312 and with RESPONSE TIMES as shown in Table 3.3-13.

APPLICABILITY: MODES 1. 2 and 3.

ACTION:

a. With a SFRCS instrumentation channel trip setpoint less con-servative than the value shown in the Allowable Values column of Table 3.3-12. declare the channel inoperable and apply the applicable ACTION requirement of Table 3.3-11, until the channel is restored to OPERABLE status with the trip setpoint adjusted consister.t with the Trip Setpoint value.

b. With a SFRCS instrumentation channel inoperable, take the action shown in Table 3.3-11.

SURVE!LLANCE REOUIREMENTS 4.3.2.2.1 Each SFRCS instrumentation channel shall be demonstrated i OPERABLE by the performance of the CHANNEL CHECK, CHANNEL CALIBPATION anc CHANNEL FUNCTIONAL TEST during the N00ES and at the frecuencies shown in Table 4.3-11, 4.3.2.2.2 The logic for the bypasses shall be demonstrated OPEPABLE i

during the at power CHANNEL FUNCTIONAL TEST of charne;s affected by i

bypass operation. The total bypass function shall be demonstrated OPERABLE at least once per 18 months during CHANNEL rJ.LIBRATION testing of each channel affected by bypass operation.

4.3.2.2.3 The STEAM AND FEEDWATER RUPTURE CONTROL SYSTEM RESPONSE TIME of each SFRCS function shall be demonstrated to be within the limit at -

least once per 18 months. Each test shall include at least one channel-per function such that all channels are tested at least once every N

! times 18 nenths where N is the total number of redundant channels in a l specific SFRCS function as shown in the " Total No. of Channels" Column of Table 3.3-11.
