These limits are applicable for the entire cycle unless otherwise scentifica These limits have been developed using the NRC approved methodologies specified in Tecnnica' Spec 5 cation 6.6.5.

2.1 Shutdown Marnin (SDM)

The SDM limit for MODES 1. 2. 3. and 4 is:

2.1.1 The SDM shall be greater than or equal to 1.3% ak/k (LCOs 3.1.1,3.1.4.3.1.5.

3.1.6,3.1.8 and 3.3.9; TRM TLCOs 3.1.b. 3.1.d. 3.1.f 3.1.h and 3.1.j).

The SDM limits for MODE 6 are:

1 2.1.2.1 SDM shell be greater than or equal to 1.0% AWk (LCO3.1.1) 2.1.2.2 SDM shall be greater than or equal to 1.3% Ak/k (LCO 3.3.9; TRM TLCO 3.1.1 and 3.1.J) 1 2.2 Moderator Temperature Cosmcient (LCO 3.1.3)

The Moderstor Temperature Coemc6ent (MTC) l6mits are:

2.2.1 The BOUARO/HZP-MTC shall be less positive t%n +3.8 x 10 Ak/k/'F.

4 2.2.2 The EOUARO/HFP MTC shall be less negative than 4.1 x 10d Ak/k/'F.

2.2.3 The EOUARO/HFP-MTC Surveillance limit at 300 ppm shall be less negative

. than or equal to 3.2 x 10d ak/k/'F.

where BOL stands for Beginning of Cycle Lrfe ARO stands for All Rods Out HZP stands for Hot Zero Thermal Power.

The normal operation W(Z) values have been determned at burnups of 150, 10000 and 17500 MWD /MTU.

Table 2.5.2 shows the FC (z) penalty factors that are greater than 2% per 31 o

EllecWve Full Power Days. These values shaR be used to increase the F*o(z) as per Surveillance Requirement 3.2.1.2. A 2% penalty factor shaR be used at all cycle bumups that are outside the range of Table 2.5.2.
