AQ. Core Ooerating Limits Recort The Core Operating Limits Report is the unit specific document that provides core operating limits for the current operating reload cycle. These cycle-specific operating limits shall be determined for each reload cycle in accordance with Specification 6.7.A.7. Plant operation within these operating limits is addressed in individual specifications.
AR. Allowable Value_ - The Allowable Value is the limiting value of the sensed process variable at which the trip setpoint may be found duting instrument surveillance.

a.
Satisfy the requirements by placing the appropriate channels or systems in the tripped condition (Turbine /Feedwater Trip only),
or j
b.
Place the plant under the specified required condition using normal operating procedures.

- This indication is reactor coolant temperature sensitive. The calibration is thus made for rated conditions. The level error at low pressures and temperatures is bounded by the safety analysis which reflects the weight-of-coolant above the lower tap, and not the indicated level.
A violation of this. acification is assumed to occur only when a device is knowingly set outside of the limiting trip settings, or, when a sufficient number o devices have been affected by any means such that the automatic function is incapable of operating within the allowable deviation while in a reactor mode in which the specified function must be operable or when actions specified are not initiated as specified.
