Revision 0 Browns Ferry Unit 2 Cycle 19 LAR Fuel Cycle Design Page 1-1 1.0 Introduction AREVA NP Inc. (AREVA) has performed a fuel cycle design and fuel management calculations for Cycle 19 operation in support of the introduction of ATRIUMTM* 1OXM fuel at the Browns Ferry Unit 2 BWR. These analyses have been performed with the approved AREVA neutronics methodology (References 1 through 5). The CASMO-4 lattice depletion code was used to generate nuclear data including cross sections and local power peaking factors. The MICROBURN-B2 three dimensional core simulator code, combined with the application of the applicable critical power correlation, was used to model the core. The MICROBURN-B2 pin power reconstruction (PPR) model was used to determine the thermal margins presented in this report.

Design results for the Cycle 19 reactor core loading including projected control rod patterns and evaluations of thermal and reactivity margins are presented. The Cycle 19 results are based on Cycle 18 core operational history as summarized in Table 2.1

Revision 0 Browns Ferry Unit 2 Cycle 19 LAR Fuel Cycle Design Page 2-1 2.0 Summary The Cycle 19 fresh batch size [ ] and batch average enrichment [

] were determined to meet the energy requirements provided by Tennessee Valley Authority (TVA) (Reference 7). For a complete description of the fresh reload assemblies, see Reference 6. The loading of the Cycle 19 fuel as described in this report results in a projected Cycle 19 full power energy capability of 2,063+/-41 GWd (15,147+/-300 MWd/MTU). Beyond the full power capability, the cycle has been designed to achieve 172 GWd additional energy via FFTR and power coastdown operation.

In order to obtain optimum operating flexibility, the projected control rod patterns for Cycle 19 were developed to be consistent with a conservative margin to thermal limits. The cycle design calculations also demonstrate adequate hot excess reactivity and cold shutdown margin throughout the cycle. Key results from the design analysis are summarized in Table 2.1. Table 2.2 summarizes the assembly identification range by nuclear fuel type batch for the Cycle 19 design. Figures 2.1 and 2.2 provide a summary of the cycle design step-through projection.

The Cycle 19 design satisfies the C-lattice Channel Bow criteria, as defined in GNF SIL-320, which is conservative for a D-lattice plant.

Peak rod average power was verified to not exceed 6.3 kW/ft at exposures of ->54 GWd/MTU (Regulation Guide 1.183 requirement).

Revision 0 Browns Ferry Unit 2 Cycle 19 LAR Fuel Cycle Design Page 3-1 3.0 Cycle 19 Fuel Cycle Design 3.1 GeneralDescription The assembly design for the Cycle 19 BFE2-19 fresh reload fuel for Browns Ferry Unit 2 is described in detail in Reference 6. Elevation views of the fresh reload fuel design axial enrichment and gadolinia distributions are shown in Appendix B, Figures B.1 through B.3. The loading pattern maintains full core symmetry within a scatter load fuel management scheme.

This loading in conjunction with the control rod patterns presented in Appendix A shows acceptable power peaking and associated margins to limits for projected Cycle 19 operation.

The analyses supporting this fuel cycle design were based on the core parameters shown in Table 3.1. Figures 3.1 through 3.5, along with Table 3.1 define the reference loading pattern used in the fuel cycle design. The specific core location of the fresh assemblies in Cycle 19 is provided in Appendix C. Key results for the cycle are summarized in Table 2.1.

3.2 Control Rod Patternsand Thermal Limits Projected control rod patterns for Cycle 19 and resultant key operating parameters including thermal margins are shown in Appendix A. The thermal margins presented in this report were determined using the MICROBURN-B2 3D core simulator PPR model to provide adequate margin to thermal limits from Reference 7. A detailed summary of the core parameters resulting from the step-through projection analysis is provided in Tables A.1 and A.2. Limiting results from the step-through are summarized in Table 2.1 and in Figure 2.2. The hot operating target k-eff versus cycle exposure which was determined to be appropriate for Cycle 19 is shown in Table 3.2. The k-eff and margin to limits results from the design cycle depletion are presented graphically in Figures 2.1 and 2.2. The k-eff values presented in Figure 2.1 and in Appendix A are not bias corrected. Selected exposure and radial power distributions from the design step-through are presented in Appendix D. Projected control rod patterns near EOC18 are shown in Appendix E.

3.3 Hot Excess Reactivity and Cold Shutdown Margin The cycle design calculations demonstrate adequate hot excess reactivity, SLC shutdown margin, and cold shutdown margin throughout the cycle. Key shutdown margin and R-Value results are presented in Table 2.1. The shutdown margin for Cycle 19 is in conformance with the Technical Specification limit of R + 0.38 %Ak/k at BOC. The cold target k-eff versus exposure determined to be appropriate for calculation of cold shutdown margin in Cycle 19 is AREVA NP Inc.

Revision 0 Browns Ferry Unit 2 Cycle 19 LAR Fuel Cycle Design Page 3-2 shown in Table 3.3. The core hot excess reactivity was calculated at full power with all rods out, 102.5 Mlb/hr core flow, with equilibrium xenon. Tables 3.4 through 3.6 summarize the Cycle 19 reactivity margins versus cycle exposure, including the SLC shutdown margin for the cycle.
