MCE1440046 Page 2 of 21 Revision 15 McGuire 1 Cycle 12 Core Operating Limits Report IMPLEMENTATION INSTRUCTIONS FOR REVISION 15 Revision 15 to the McGuire Unit 1 COLR is required to supp,rt the increase in the upper j
boron concentration limit for the RWST and CLA to 2875 ppm. This revision shall be j
implemented after Emergency Procedures (EP's) for hot leg circulation switchover time j
are revised to accommodate the higher RWST and CLA boron concentralians. Refer to Engineering Instruction MCEl-0400-100, Rev.1 (r/ hot leg recirculation switchover time).
