TO: ALL UNIT 2 TECHNICAL l SPECIFICATIONS MANUAL HOLDERS l ) By amendment 106 to the Unit 2 Technical Specifications, the NRC authorized relocation l of certain fuel-related limits from the Technical Specifications to the adjunct Core Operating Limits Report (COLR). This letter transmits to all Unit 2 Technical Specifications manual holders a copy of Revision 0 of the COLR for Hatch 2 Cycle 12. This document should be utilized in conjunction with the Unit 2 Technical Specifications, as referred to in the Specifications. Normally, the shift technical advisor or reactor engineer will use this report.

   '      Where necessary, the fuel limits from the COLR are included in plant procedures.

Please discard Revision 0 of the COLR for Hatch 2 Cycle 11, which was issued in November 1992, since it is no longer applicable. If you have questions regarding Revision 0 of the Unit 2 COLR for Cycle 12, please contact me at extension 8-821-7392 or telephone number (205) 877-7392. SRPf sp l nan r Enclosure O cc: NORMS O O

The core operating limits presented herein were developed using NRC-approved methods (Refe-rences 1 and 2). Results from the reload analyses for the General Electric (GE) fuel in Unit 2 Cycle 12 are documented in References 3 and 4.

The following cycle-specific core operating limits are included in this report:

a. Control Rod Program Controls - Technical Specification 3/4.1.4.3.
b. Average Planar Linear lleat Generation Rate (APLIIGR) -

Technical Specification 3/4.2.1. , c. Minimum Critical Power Ratio (MCPR) - Technical Specification 3/4.2.3.

d. Linear IIcat Generation Rate (L.HGR) - Technical Specification 3/4.2.4 2.0 ROD BLOCK MONITOR (Technical Specification 3/4.1.4.3)

Both Rod Block Monitor (RBM) channels shall be operable as specified in O- Technical Specification 3/4.1.4.3 and when:

a. TilERMAL POWER is < 90% of RATED THERMAL POWER l- and the MCPR is < 1.70 or
b. TIIERMAL POWER is.2. 90% of RATED THERMAL POWER-

,g and the MCPR is < 1.40. , >%)

3.0 APLHGR LIMIT (Technical Specification 3/4.2.1) The APLHGR limit is given by the applicable rated power, rated flow limit taken from Figures 3-3 through 3-8, multiplied by the smaller of either: l

a. The factor given by Figure 3-1 or l \

l

b. The factor given by Figure 3M l For the fuel types whose APLHGR limits are shown in Figures 3 3 through 3-8, the APLHGR limit shall be applied to each axial location in the fuel assembly.

i As required by GESTAR Amendment 19, the hand-calculated APLHGR values for a multi-lattice (i.e., GE8-296 and Gell-LUA) fuel must be less than or equal to the APLIIGR limits shown in Figures 3-4 and 3-7, respectively. When .O ^ v ' " o n v"i"e> =re determi"ea 8 the 7 vroee>8 ee m n"ter the iettiee-dependent APLHGR limits are used. Under these conditions, some axial , locations may have APLHGR values exceeding the values shown in Figures 3-4 ) and 3-7. l l l i, O O. Revision 0 2 April 1994

The NICPR operating limit (OLh1CPR) is a function of fuel design, average scram time, core flow, number of operating recirculation loops, and core power. Note that in Figure 4-3, the rated-power and rated-flow OLMCPR is fuel-type dependent; e.g., the Option B limits are 1.22 for GE7B, GESB, and GE9B fuels, and 1.28 for Gell fuel. Os 4.1 Two Recirculation Loon Operation For 259E.1 power < 309c, the OLMCPR is given in Figure 4-1. For power 2. 3092, the OLhiCPR is the greater of either:
