SURVElLLANCE REQUIREMENTS 4.2.1.1 The nrovisions of Specification 4.0.4 are not applienble.
4.2.1.2 The linear heat rate shall be determined to be within its limits when TilERMAL POWER is above 207. of RATED TilERMAL POWER by continuously monitoring the core power distribution with the Core Operating Limit Supervisory System (COI.SS) or, with the COLSS out of service, by verifying at least once per 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> that the linear hont rate, as indicated on any OPERABLE CPC channel, is within the limit shown on Figure 3.2-1.
4.2.1.3 At least once por 31 days, the COLSS Margin Alarm shall be verified to actunto at a TIIERMAL POWER level less than or equal to the core 1
power operating limit based on linear heat rate.
