U-601730 LS-87-039 Page 16 of 22 INSTRUMENTATION 3/4.3.6 CONTROL ROD Bt0CK INSTRUMENTATION L1HITING CONDITION FOR OPERATION 3.3.6 The control rod bicek instrumentation channels shown in Table..'.3.6-1 shall be OPEPABLE, with their trip setpoints set consistent with the vtlues shown in the Trip Setpoint column of Table 3.3.6-2.

APPLICABILITY: As shown in Table 3.3.6-1.

ACT10tt:

a. With a control rod block instrumentation channel trip setpoint less conservative than the value shown in the Allowable Value column of Table 3.3.6-2, declare the channel inoperable until the channel is restored to OPERABLE status with its trip setpoint adjuste$ consistent with the Trip Setpoint value,
b. With the number of OPEPABLE channels less than required by the Minimum OPERABLE Channels per Trip Function requirement, take the ACTION required by Table 3.3.6-3.

SURVE1LLANCE REO,UIREMENTS 4.3.6.1 ach of the'above required control rod block trip systems and instru- l men ton channels shall be demonstrated OPERABLE by the performance of the CHANNEL CHECK, CHMNEL FUH0TIONAL TEST and CHANNEL CALIBRATION operations for the OPEPATIONAL CORDITIONS and at the frequencies shown in Table 4.3.6-1.
