• OPERA TING LIMITS The cycle-specific parameter limits for the specifications listed in Section l.O are presented in the following subsections. These limits have been developed using the NRC-approved methodologies specified in Technical Specification 6.9. l. 9.

2.1 Moderator Temperature Coefficient (Specification 3/4.1. l .4) 2.1. l The Moderator Temperature Coefficient (MTC) limits are:

The BOUAROrrIZP-MTC shall be less positive than 0 Afclk/°F.

The EOUARO/RTP-MTC shall be less negative than 4.4x 10-4 ~°F.

2.1.2 The MfC Surveillance limit is:

The 300 ppm/ARO/RTP-MfC should be less negative than or equal to-3.7xiQ-4 ~°F.
