INTRODUCTION'his Core Operating Limits Report for Browns Ferry Unit 2, Cycle 9 is prepared in accordance with the, requirements, of Browns Ferry Technical Specification 6.9.1.7.
The core operating limits presented here were developed using 'NRC-approved methods (References 1 and 2).
Results from the reload analyses for.Browns Ferry Unit 2, Cycle 9 are documented in Reference 3.
The following core operating limits.are included in this, report:
a.
Average Planar Linear Heat Generation Rate (APLHGR) Limit (Technical Specification 3.5.'I)
- b. Linear Heat'Generation Rate (LHGR) Limit (Technical Specification 3.5.Q
- c. Minimum Critical Power Ratio Operating Limit(OLMCPR)
(Technical Specification 3.5.K/4.5.K) d.
Average Power Range Monitor'(APRM) Flow Biased Rod Block Trip Setting (Technical Specification 2.1..A. 1'.c, Table 3.2.C, and Specification 3.5.L) e.
Rod Block Monitor (RBM) Upscale (Flow Bias) Trip.Setting and Clipped Value (Technical Specification Table 3.2.C)
- 2. APLHGR LIMIT(TECHNICALSPECIFICATION 3.5.I)
The APLHGR limit for each. type of fuel as, a function of exposure is shown in
'ables 1 - 8. The APLHGR limits,for the GE9B (GE8X8NB).and the GE11 bundles,
',are for the most limiting lattice at each" exposure point. The specific values for each lattice are given in Reference 4.

- 3. LHGR LIMIT(TECHNICALSPECIFICATION 3.5.J)
The LHGR'limitfor unit 2 cycle 9 is fuel type dependent, as shown below:

- 4. OLMCPR,(TECHNICALSPECIFICATION 3.5.K/4.5.K) a.
The OLMCPR is equal to the:fuel type and exposure dependent MCPR limit at rated flow and rated power shown-in Figures 1 - 3 multiplied by the Kf shown in Figure 4, where; Save ZB Z = 0.0 or Z,
whichever is greater.

where:
SRB = Rod Block setting. in percent of rated thermal power (3293 MWt)
W = Loop recirculation flow rate in percent of.rated Note:
Under certain conditions, the APRM Rod Block setting must'be adjusted by FRP/CMFLPD.
See Technical Specification 3.5.L.
- 6. RBM UPSCALE'(FLOW BIAS) TRIP SETTING AND CLIPPED VALUE (TECHNICALSPECIFICATION TABLE'3.2.C)
Tlie RBM Upscale trip setting shall be:
