Content:
information has been provided by the applicant and that the review and any calculations support conclusions of the following type, to be included in the staff's safety evaluation report: The staff has reviewed the fission product scrubbing function of the pressure suppression pool and finds that the pool will reduce the fission product content of the steam-gas mixture flowing through the pool following accidents that blow down through the suppression pool. The staff estimates that the pool will decontaminate the flow by a factor of ______ for molecular iodine vapor and by a factor of ______ for particulate fission products. No significant decontamination of noble gases and organic iodides will occur in the pool. The system is largely passive in nature, and the active components are suitably redundant so that its fission product attenuation function can be accomplished assuming a single failure. The applicant's proposed program for preoperational and surveillance tests will ensure a continued state of readiness, and that bypass of the pool is unlikely to exceed the assumptions used in the dose assessments. The staff concludes that the pressure suppression pool as a fission product cleanup system is acceptable and meets the requirements of General Design Criterion 41 with respect to the iodine removal function following a postulated loss-of-coolant accident, General Design Criterion 42 with respect to the capability for periodic inspection of the system, and General Design Criterion 43 with respect to the capability for periodic testing of the system. For design certification reviews, the findings will also summarize, to the extent that the review is not discussed in other safety evaluation report sections, the staff's evaluation of inspections, tests, analyses, and acceptance criteria (ITAAC), including design acceptance criteria (DAC), site interface requirements, and combined license action items that are relevant to this SRP section.15 6.5.5-7 DRAFT Rev. 1 - April
