Remarks: This ENN-DC-126 MCC is to a VY design verified calculation prepared under AP-0017.

AP-0017 did not have a "checklist", instead design verification was documented on form VYAP0017.04.

ENN-DC-1 26, REv. 4, ATrACHMENT 9.8 MINOR CALCULATION CHANGE FORM Section 5. Description of Change Discussion The minor change to VYC-2314 addresses condition report CR-VTY-2004-02206 [Reference 28]. The condition report documents an error in the vendor calculation [Reference 221 that was used as a design input for MCC/CCNOI. As a result, design input Reference 22 is deleted and the revised vendor calculation in Reference 29 is incorporated as design input in this MCCICCN02.

The error in the vendor calculation was associated with the mixing efficiency of the drywell sprays. Assuming 100% mixing efficiency reduces the available containment pressure.

The increased drywell spray efficiency does not adversely affect the primary containment pressure response used in the net positive suction head evaluations. GE performed the evaluation for the post-LOCA containment response with the increased primary containment leakage rate of 1.5 wt-% per day and 100% drywell spray mixing efficiency [Reference 29]. The updated results of the evaluation were compared to the 0.8 wt-% per day results [Reference 71. The increased leakage rate with 100% drywell mixing efficiency results in approximately 032 psi decrease at about 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. Table I provides a comparison of the suppression pool pressure results.

The conclusions from the GE post-LOCA results are applicable to the non-LOCA calculations in VYC-2314.

Leakage rate or flow is proportional to the square root of the AP (conversely, AP =cis 2 ). The post-accident LOCA AP (drywell to atmosphere) bounds the non-LOCA cases. As a result, the 0.32 psi decrease at 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> post-LOCA is also bounding for the non-LOCA events. The "Summary of Results" in VYC-2314 Revision 0 documents the margin available for the non-LOCA NPSH evaluations is in the order of 3 to 5 psig. A maximum decrease of 0.32 psi will still provide adequate NPSH margin at the 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> time of interest.

Results from 8035.1 seconds and beyond are conservatively selected and assigned to the same time.

The drywell spray mixing efficiency of 100% has an insignificant impact on suppression pool pressure. The time frame of interest in the present calculation is approximately 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, therefore the 0.32 psi reduction in suppression pool pressure due to 1.5 weight-% per day primary containment leakage and 100% drywell spray mixing efficiency is bounding.

Conclusion This MCC does not change the results in the existing calculation (VYC-2314, Revision 0). The MCC documents the primary containment leakage rate assumption of 1.5 wt-% per day with 100% drywell spray mixing efficiency. The need for crediting suppression pool overpressure in the RHR and CS NPSH evaluation shall also be addressed in the SADBD (Reference 17), UFSAR (Reference 23), system DBDs RHR (Reference

24) and CS (Reference 25), NEDC-33090P (Reference 26) and VYDC-2003-008 (Reference 27). These documents are listed in the attached AP0017.07 form as design output documents.

Note that the changes to the UFSAR were originally proposed in VYDC-2003-008 and are pending incorporation via the design change and licensing processes. The use of overpressure credit must be approved by the NRC as part of EPU. This MCC simply updates a design input parameter in the calculation that was performed under AP-0017.

No specific 50.59 Screening/Evaluation is required for this MCC/CCN since all EPU design changes and associated 50.59 documentation will be part of VYDC-2003-008 (Reference 27).
