s LIMITING CONDITIONS FOR OPERATION SURVEILLANCE REQUIREMENTS

  1. 4.11 REACTOR FUEL ASSEMBLY 3.11 REACTOR FUEL ASSEMBLY Applicability: Applicability The Limiting Conditions for Operation associated with fuel The surveillance requirements rods apply to those parameters apply to the parameters which which monitor the fuel rod the fuel rod operating operating conditions. conditions.

Objective:

Objective:

The Objective of the Limiting Conditions for Operation is to The Objective of the assure the performance of the Surveillance Requirements is to fuel rods. specify the type and frequency of surveillance to be applied to the fuel rods. ,,

Specifications:

Specifications A. Average Planar Linear Heat Generation Rate (APLHGR) A. Average Planar Linear Heat Generation Rate (APLHGR)

During power operation with both recirculation pumps operating, The APLHGR for each type of the APLHGR for each type of fuel fuel as a function of average as a function of average planar planar exposure-shall be exposure shall not exceed the determined daily during reactor applicable limiting value shown operation at >25% rated thermal in Figures 3.11-1 through power.

3.11-7. The top curves are applicable for core flow greater than or equal to 90% of rated core flow. When core flow is less than 90% of rated core flow, the lower enrves shall be '

lic.i ii ng. If at og time during operation it is determined by normal surveillance that the limiting value for APLHGR is being exceeded, action shall be initiated within 15 minutes to restore operation to within the prescribed limits. If the APLHGR is riot returned to within the prescribed limits within two (2) hours, the reactor shall be brought to the Cold Shutdown condition within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Surveillance and corresponding action shall continue until reactor operation is within the prescribed limits.
