Branch Status Summary

  • Containment and Ventilation

- 13 draft RAIs issued

- Resolution of EPITOME code error Code error involves LOCA mass and energy release calculation Turkey Point containment analysis is impacted Plant operability has been addressed Identifying analytical and operational margins Affected EPU documents have been identified Schedule for resolution under development 10

Branch Status Summary

  • Containment and Ventilation

- Debris generation and NPSH considerations EPU has no effect on insulation debris generation EPU has no effect on sump flow Classic NPSH requirements are met without credit for containment overpressure Containment overpressure provides margin to address potential flashing and de-aeration effects
