e REQUEST FOR ADDITIONAL INFORMATION MILLSTONE NUCLEAR POWER STATION. UNIT ?

QQCKET NO. 50-423 TAC M99796 (1). - Proposed Limiting Condition ior Operatioa (LCO) statement 2.2.1 does not reflect its heading requirement and does net refor to the table that lists the setpoints. Plea -

justify.

(2) Instrument operability requirements are stated in LCO 3.3.1, why lo it needed twice

-(proposed LCO 2.2.1 and existing LCO 3.3.1)? Please justify.

4 (3) in the current Technical Specifications (TS), if the reactor trip system instrumentation or interlock setpoint is less conservative than the allowable value, the TS require adjusting th3 setpoint consistent with the trip setpoint value of Table 2.2-1 and determining within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> that equation 2.2-1 was satisfied for the affected channe', or declaring the enanne.1 inoperable and following the action in T Sie 3.3.1. For the proposed amendment, the Bases state that if the value is wund to be in excess of allowable value, but within the administratively controlled limit, the channel is onerable and must be calibratad per the plant procedure. As such, the channel operability is controlled by an administrative procedure and not by TS. Please justify.
