Meshod and Schedule of Verification for Unverified NDITs: Hewtytton ofInformation: Attached is the Braidwood Unit 2 Cycle 8 Core Operating 1.imits Report (COLR) in the ITS fomiat and W(r) runcinon. Purpose orInformation* . Sequence 1 of this NDIT supersedes NDIT NFM9900022. Seq. 4. This COI,R incrwpcentes the ITS format and W(7.) function. Sequence I lacorporanes a revised K(Z) curve for assembly everage burnup $ 4000 MWD /MTU due to the recent issue on the LOCBART code discrepancy affecting 1.81KA analysis. Broidwood Station is rcquested to perform an Independent Technical Review (ITR) cithis docurnanL Upon -: .' h of the ITR. Braidwood Station is to transmit the COLR portion to the Nuclear Regulatory Commnssion. Please provide nrm (Rob Lsc) with a copy of Braidwood Stasson's completed rTR and COLR submittal in the NRC. source ofinformation: 1) PND Calculation Number PC41. "BR2C8 W(a) Curve Generation."

- 2.0 OPERATING LIMITS The cycle-specific parameter limits for the specifications listed in Secten 1.0 are preserited in the tollowing subsechons. These limits are applicable for the entire cycle unless otherwise identified.
These limits have been developed using the NRC-approved methodologies specified in Technical Spec 3c i;cni 5.6.5. 2.1 Shutdown Marain (SOMJ 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, 31.5, 3.1.6, 3.1.8, 3.3.9, and 3.9.1; TRM TLCOs 3.1.b,3.1.d, 3.1.f, 3.1.h, and 3.1.J)
The SDM limits for MODE 5 are: 2.1.2.1 SDM shall be greater than or equal to 1.0% Ak/k (LCO 3.1.1). 2.1.2.2 SDM shall be greater than or equal to 1.3% Ak/k (LCO 3.3.9; TRM TLCO 3.1.i and 3.1.j). 2.2 Moderator Temperature Coefficient (LCO 3.1.3) The Moderator Temperature Coefficient (MTC) limits are: 2.2.1 The BOUARO/HZP-MTC shall be less positive than +3.7 x 104Ak/k/*F. 2.2.2 The EOL/ARO/HFP-MTC shall be less negative than -4.1 x 10d Ak/k/'F. 2.2.3 The EOL/ARO/HFP-MTC Surveillance limit at 300 ppm shall be less negative than or equal to -3.2 x 10dAk/k/'F. where: BOL stands for Beginning of Cycle Li'e ARO stands for All Rods Out HZP stands for Hot Zero Thermal Power EOL stands for End of Cycle Life s R"o tands for Hot Full Thermal Power i i
