De cycle specific parameter limits for the specifications listed in section 1.0 are presented in the following subsections. These limits have been developed using NRC approved methmlologies specified in Technical Speelfication 6.9.1.9.

! 2.1 Modernene Temnerneure (%,tricient #Rn.cirtention 3/11.1.3)

2.1.1 ne Moderator Temperature Coefficient (MTC) Limits are
,

The MTC shall be less positive than the limits shown in Figure 1. The ,

BOC/ARO/lizP MTC shall be less positive that 0.7

  • 104 AK/KrF.

The EOC/ARO/RTP MTC shall be less negative that .4.1

  • 104 AK/KtF.

t 2.1.2 ne MTC Surveillance Limit is:

The 300 PPM /ARO/RTP MTC should be less negative than or equal to 3.2

  • 104 AK/KrF.

Where: BOC stands for Beginning of Cycle ARO stands for All Rods Out ilZP stands for llot Zero (Dermal) Power EOC stands for End of Cyc!c RTP stands for Rated Thennal Power 1
