- 15. Stability. Analysis Results GE SIL-380 recommendations have been included in the River Bend Station operating procedures and Tech-nical Specifications; therefore, the stability analysis is not required. NRC approval for deletion of a cycle-
! specific stability analysis is documented in Amendment 8 to NEDE-240ll-P-A-US. River Bend Station i recognizes the issuance of NRC Bulletin No. 88-07, Supplement 1, Power Oscillations in Boiling Water l Reactors (BWRs), and will comply with the recommendations contained therein.
- 16. Loss-of-Coolant Accident Results LOCA method used: SAFE /REFLOOD De following table lists the least limiting and most limiting MAPLHGRs for the new fuel: The core-wide metal water reaction is <0.23% De peak clad temperature is 62189'F at all exposures; the local oxidation (fraction) is $ 0.060. De MAPLHGR multiplier for single-loop operation is 0.84 for all fuels in the core.

RIVER BEND 24A5188 Reload 6 Rev.O Appendix B Alternate Analysis for Feedwater Temperature Reduction To provide for improved operating flexibility and cycle extension for Cycle 7, expanded operating domain analyses were performed forIncreased Core Flow (ICF) at 107 % rated and intermittent use of Final Feedwater Temperature Reduction (FFWTR) to a temperature (at full power) of 320 degrees F. T he analyses for cycle extension with ICF were performed at EEOC78 exposure point using appropriate thermal hydraulic condi-tions. The analyses for cycle extension with ICF and FFWTR was performed at EEEOC79exposure point achieved with ICF and FFWTR using the appropriate thermal hydraulic conditions. Contained in this license submittal are results of all analyses evaluated for this licensing activity. The transient MCPR values for all analyses are given in Section i1. The analyses for ICF and FFWTR bound the intermittent concurrent use of FFWTR from BOC to EEEOC operation with ICF and FFWTR.
The Final Feedwater Temperature Reduction (FFWTR) extension flexibility option cannot be exercised until the GE Nuclear Service organization has completed their work and evaluation.

Appendix D I Basis for Analysis of Core-Wide and Overpressurization Transients I
l The Core-Wide and Overpressurization Transients were analyzed with four valves out of sixteen operable I in relief mode and five valves out of sixteen operable in safety mode. The seven inoperable S/RV's are appli-cable only to the Vessel Overpressure ASME Code Compliance upset condition and fuel thermal performance criteria. The analyses performed reflect the River Bend Station Technical Specifications, which permit operation with 4 valves in relief mode and 5 valve:. in safety (spring) mode.
In addition , the core-wide pressurization transients and overpressurization transients were evaluated with new opening setpoints on the S/RV's. The GE Nuclear Services analysis is still not complete and these set points cannot be implemented until such time as their evaluation has been completed.

RIVER BEND 24A5188 Reload 6 Rev.0 Appendix F Basis for Analysis of Standby Liquid Control System Shutdown Capability l
The minimum required boron shutdown margin is dependent on the fuel design type and the calculational j method. The minimum required boron shutdown margin represents the biases and uncertainties needed to assure suberiticality. This is a GE recommended value and may be less restrictive than the River Bend specific technical spesifications requirement for the liquid boron shutdown margin, in which case the technical speci-fication value shall be used. For the analysis reported in this Supplemental Reload Licensing Submittal fuel specific borated libraries were generated using lattice physics methods at 160 deg. C and 724 ppm boron.
A boron concentration of 724 ppm boron at 160 deg. C is equivalent to 660 ppm boron at 20 deg. C resulting from the change in water density and inventory. The margin requirements to satisfy for this method with gel 1 in the core is 1.4%.

Plant Operation Above the i Rated Load Line Up to Rated Power l
l For River Bend Station, Reload 6/ Cycle 7 analyses have been performed in addition to the standard reload analyses to support operation in the extended operation region. The consequences of the AOO's have been evaluated to determine if operating limits reported in Section 11 are bounding for operation in the extended operating range. The analyses were performed at 100% power and 91% flow with both normal feedwater temperature and reduced feedwater temperature. The results of the calculations are reported below and are bounded by the OLMCPR operating limits of 1.28 for the GElI fuel and 1.22 for the GE8 fuel reported in Section i1 of the Supplemental Reload Licensing Report.
