section 1.0 are presented in the following subsections. These limits have been developed using NRC-approved methodologies specified'in Technical Specification 6.9.1.9 2.1 Moderator Temperature Coef ficient (Specification 3/4.1.1.3) 2.1.1 The Moderator Temperature Coefficient (HTC) Limits are:

The MTC shall be less positive than the limits shown in Figure j'e- l. (The BOL,.sR0/HZP-MTC shall be less positive than 0.7 x 10-4

( AK/K/'F).

The E0L/ARO/RTP-MTC shall be less negative than -4.1 x 10~4 AK/K/*F.

2.1.2 The MTC Surveillance Limit ist i

The 300 PPS/ARO/RTP-MTC should be less negative than or equal to
