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 !imits is addressed in individual specifications.

AR. Allowable Value - The Allowable Valese is the limiting value of the sensed process variable at which the trip setpoint may be found during instrument surveillance.

Upon discovery that minimum requirements for the number of operable or operating trip systems or irstrument channels are not t

satisfied, action shall be initiated as follows:

With more than one instrument channel per trip system inoperable, immediately satisfy the requirements by placing the appropnate channels or systems in the tripped condition, or c.

Flace the plant under the specified required condition usmg normal operating procedures.

  • This indication is reactor coolant temperature sensitive. The calibration is thus made for j

rated conditions. The level err:,r at low pressures and temperatures is bounded by the j

safety analysis wh ch reflects the weight-of-coolant above the lower tap, and not the indicated level.

A violation of this specification is assumed to occur only when a device is knowingly set outside of the limiting trip settings, or, when a sufficient number of 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.
