The B-10 enrichment to be used in the SLCS for LaSalle 1, has been changed from
.18.9% to 45%. Conservatively, a concentration of 800 ppm of natural Baron was used for this reload licensing analysis because the actual Technical Specification minimum Boron Concentration (including allisotopes)is no less than 660 ppm.
The methodology documented in NFD-ND-900-1 Appendix B, Procedure 8.3 was J used.

- 6. Loading Error Results q The fuelloading error includes both the mislocated bundle event and u,e misoriented bundle event. GE indicated in Reference 10 that if the operating limit MCPR will be >- 1.28 (as it will be for this cycle), then the mislocated bundle analysis is not required. Use of this bounding value of 1.28 implies a ACPR of {
0.21, which is reported here for the fuel loading error. The ACPR for the I misoriented bundle event is less than 0.21. Therefore, the fuel loading error l event is bounded by the 1.28 MCPR for the mislocated bundle event and its l associated 0.21 ACPR. j Event /ff_g Fuel Loading Error 0.21 {

Loss of Feedwater Heating 1,23 1 l
Rod Withdrawal Error 1.35 (for unblocked RBM setpoint)
Fuel Loading Error 1.28 These MCPR Operating Limits are based on a MCPR Safety Limit of 1.07.
- 8. Control Rod Drop Analysis Results LaSalle is a benked position withdrawal sequence plant, so the control rod drop accident (CRDA) analysis is not required for startups or normal operation. NRC approval is documented in References 11 and 12. However,in order to allow the i site the option of inserting control rods using the simplified centrol rod sequence shown in Table 1, a control rod drop accident analysis was performed for the simplified sequence. The results demonstrate that the 280 cal /gm Technical l Specification Limit is not exceeded. The simplified sequence is thus valid for LaSalle 1 Cycle 8.
j 9. Maximum Exposure Limit Compliance The maximum nodal exposure achieved during LaSalle 1 Cycle 8 is 45507 mwd /ST. This corresponds to 88% of the design limit. The maximum nodal exposure occurs in the bundle located at 09-42 in node 10. This value ensures that no exposure limits will be reached during normal cycle operation.

Appendix B Impact of Change to the APRM Flux Scram Setpoint l
'Ihe APRM High Neutron Flux Analytical Limit has been changed from 122.4% to 124.2%. This change has -
been incorporated into Overpressure Analysis described in Section 12. The review of non-pressurization events required by GESTAR is the responsibility of Comed. This change will not cause other non-limiting l AOO events to become limiting. This change has been incorporated in the the off-rated flow dependent limits defined in B33-0029p-03P, Updated Transient Analysis: AbnormalStart-up ofan Idle Recirculation Loop for LaSalle County Nuclear Station, Unlu 1 and 2, March 1998. -

See Figure A-1 Reactor cott stability ratio, yfxo : 0.78 Channel hydrodynamic performance decay ratio, ygxo :
Hot Channel Decav Ratio GE 8x8NB 0.65
- 1. This stability analysis was performed using verified and NRCmviewed code::. and 'the current reloa procedure. This is not intended to be a bounding analysis however, and the calculated value for the core and channel decay ratios may not be indicative of plant stability under some conditions. Oscillations may occur in sp ratios which are calculated to be significantly less that 1.0. For this reason, Commonwealth Edison Compan not rely on this calculated decay ratio as a basis for avoiding or delaying implementation of the latest GE and NRC guidance in tids area.
The main usefulness of these analysis results is to provide a comparison with previous cycle analysis results re to core and fuel design differences.
