Proposed License Amendment Design and Licensing Bases Considerations
- Post-accident sump pH control
- Retention of radioiodine in sump water/leakage
- Effectiveness of containment sprays and long-term retention of radioiodine in sump water is dependent on pH
- Corrosion rates
- Rates in non-neutral pH solutions are increased
- Hydrogen generation rates
- Hydrogen release not risk-significant
- Equipment Environmental Qualification components
- On-going evaluations I

Proposed License Amendment Impact on Radiological Analyses
- Retention of radioiodine in sump water
- Spray removal and retention would not be credited due to loss of pH control
- Preliminary analyses indicate
- 10 CFR 100 limits will be met Predicted dose increases but remain within acceptable limits
- General Design Criteria (GDC) 19 limits will be met
- Predicted dose increases but remain within acceptable limits with KI and use of Tracer Gas test results "I,.
