WATERFORD 3 CORE OPERATING LIMITS REPORT CYCLE 9, REVISION 2 l

1.

INTRODUCTION

-]

This CORE OPERATING LIMITS REPORT (COLR) has been prepared in accordance with the requirements of Waterford 3 Technical Specification 6.9.5 for Waterford 3 Cycle 9. The core operating limits have been developed using the NRC approved methodologies specified in Section Ill. This is Revision 2 of the Cycle 9 COLR.

l Changes included in this revision are:

1)

Revise COLR 3.1.3.1 to resolve a potential problem. COLR 3.1.3.1 could possibly have been read to permit operation with more than one Control Element Assembly (CEA) misaligned from the other CEAs in its group regardless of magnitude provided power was reduced. Change increases the level of detali of the COLR but does not change its intent or scope.

2)

Revise COLR Figure 4 to provide consistency between it and Figure 5, the Part-Length CEA Insertion Curve.

3)

Revise COLR Figures 6 and 7 to reduce Allowable Peak Linear Heat Generation Rate (PLHGR) by 0.2 kw/ft. This change compensates for an error in the Energy Redistribution Factor (ERF) used in the LOCA analysis.

4)

Revise COLR 3.2.7 to resolve apparent discrepancy. COLR Figures 8 and 9 do not allow Axial Shape Index (ASI) to be less than -0.17; however, COLR 3.2.7 indicates the acceptable range for ASI is -0.22 to +0.22.

DNBR MARGIN 3.2.4 The DNBR limit shall be maintained by one of the following methods; a)

When COLSS is in service and neither CEAC is operable: maintain COLSS calculated core power less than or equal to COLSS calculated core power operating limit based on DNBR decreased by 13% RATED THERMAL POWER.

b)

When COLSS is out of service and at least one CEAC is operable: operate within the Region of Acceptable Operation shown on COLR Figure 8, using any operable.

CPC channel.

c)

When COLSS is out of service and neither CEAC is operable: operate within the Region of Acceptable Operation shown on COLR Figure 9, using any operable CPC channel.
