VENTING 1.39 VENTING is the controlled process of discharging air or gas from a confinement to maintain temperature, pressure, humidity, concentration or other operating condition, in such a manner that replacement air or gas is r.ot provided or required during venting. Vent, used in system names, does not imply a VENTING process.

END-OF-CORE LIFE

• 1.40 END-OF-CORE LIFE shall correspond to a reactor operating condition with all control rod banks fully withdrawn, essentially 0 ppm boron concentration in the reactor coolant, and the Reactor Coolant System average temperature (Tavg) no longer maintained at normal operating temperature or the normal rated thermal power (RTP) no longer maintained.

3.17 POWER DISTRIBUTION LIMITS 3.17.1 AXIAL-OFFSET l

FOUR LOOPS OPff,,A,llE 1'

LIMITING CONDITION FOR OPERATION 3.17.1.1 The AXIAL OFFSET shall be maintained within the limits of figures 3.17-1 a, b, or c. l APPLICABILITY: MODE 1 ABOVE 40% cf RATED THERMAL POWER. I ACITE:

With the AXIAL OFFSET outside the Acceptable Operation Limits specific in the above figures, within 15 minutes initiate corrective action and continue the corrective action so that the Axial 0FFSET is within limits within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> or reduce THERMAL POWER to less than 40% of RATED THERMAL POWER within the next 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

SURVEILLANCE REQUIREMENTS

a. The AXIAL OFFSET shall be determined to be within the Acceptable Operation Limits of Figures 3.17-la, b, or c by monitoring the AXIAL l OFFSET using at least two OPERABLEI excore Power Range channels and  :

applying the excore/incore correlation on a continuous basis.

b. The excore/incore correlation shall be verified at least once per 31 EFPD and adjusted at least once per 92 EFPD using the results of the measurements obtained in accordance with Specification 3.17.2.

c. iihe excore/incore correlation shall be determined after each fuel loading or major change in excore Power Range instrumentation prior to exceeding 80% of RATED THERMAL POWER.

d. The excore Power Range detectors shall be calibrated / correlated  !

relative to the Novable Incore Detector System measurements within 7 days after completion of incore measurements.
