1.0 INTRODUCTION

The Core Operating Limits Report (COLR) been prepared in accordance with the Specification 6.2.C.

for Surry 1 Cycle 15 has requirements of Technical The technical specifications (TS) affected by this report are:

TS 3.l.E.l & TS 5.3.A.6.b - Moderator Temperature-coefficient TS 3.12.A.2 & TS 3.12.A.3 - Control Bank Insertion Limits TS 3.12.B.1 & TS 3.12.B.2 -

Power Distribution Limits S1Cl5/LT COLR Rev 0 Page 2 of 6

2.0 OPERATING LIMITS The cycle-specific parameter limits for the specifications listed in Section 1.0 are presented in the following subsections.

These limits have been developed using the NRC-approved methodologies specified in TS 6.2.C.

2.1 Moderator T!3mPerature Coefficient (TS 3.1.E.l & TS 5.3.A.6.b) 2.1.1 The Moderator Temperature Coefficient (MTC) limits are:

+6.0 pcm/°F at less than 50 percent of RATED POWER, or

+6.0 pcm/°F at 50% of Rated Power and linearly decreasing to O pcm/°F at Rated Power 2.2 Control Bank Insertion Limits (TS 3.12.A.2) 2.2.1 The control rod banks shall be limited in physical insertion as shown in Figure 1.
