INSTRUMENTATION STEAM AND FEEDWATER RUPTURE CONTROL SYSTEM INSTRUMENTATION LIMITING CONDITION FOR OPERATION 3.3.2.2 The Steam and Feedwater Rupture Control System (SFRCS) instrumen-tation channels shown in Table 3.3-11 shall be OPERABLE with their trip setpoints set consistent with the values shown in the Trip Setpoint column of Table 3.3-12 and with RESPONSE TIMES as shown in Table 3.3-1 APPLICABILITY: MODES 1, 2 and 3.

ACTION:

With a SFRCS instrumentation channel trip setpoint less con-a.

servative than the value shown in the Allowable Values column of Table 3.3-12, declare the charnel 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 consistent with the Trip Setpoint value, b.

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

SURVEILLANCE REOUIREMENTS 4.3.2.2.1 Each SFRCS instrumentation channel shall be demonstrated OPERABLE by the performance of the CHANNEL CHECK, CHANNEL CALIBRATION and CHANNEL FUNCTIONAL TEST during the MODES and at the frequencies shown in Table 4.3-11, 4.3.2.2.2 The logic for the bypasses shall be demonstrated OPERABLE during the at power CHANNEL FUNCTIONAL TEST of channels affected by bypass operation.

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

4.3.2.2.3 The STEAM AND FEE 0 WATER RUPTURE CONTROL SYSTEM RESPON of each SFRCS function shall be demonstrated to be within the limit at least once per 18 nunths.

Each test shall include at least one channel per function such that all channels are tested at least once every N times 18 months where N is the total numbe of redundant channels in a specific SFRCS function as shown in the " Total No of Channels" Column of Table 3.3 11.
