3 1J LIMITING CONDITION FOR OPERATION i;

3.2.1 The linear heat rate limit (of Figure 3.2-1) shall.be ina!ntained by one l

of the following methods as applicable; a.

Maintaining COLSS calculated core power less than or equal to COLSS calculated core power operating limit based on ' linear heat rate (when COLSS is in' service); or b.

Operating within the region of acceptable operation of Figure 3.2-la using any operable CPC channel (when COL 55 is out of service).

APPLICABILITY:

MODE 1 above 20% of RATED THERRAL POWER.

ACTION:

4.2.1.1 lhe provisions of Specification 4.0.4 are not applicable.

4.2.1.2 The linear heat rate shall be determined to be within its limits when THERMAL POWER is above 20% of RATED THERMAL 90WER by continuously monitoring the core power distribution with the Core Operating Limit Supervisory System (COLSS) or, with the COLSS out of service, by verf fying at least once per 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months that the linear heat rate, as indicated on any OPERABLE Local Power Density channel, is within the limits shown on Figure 3.2-la.
