tainment venting. 3. System Design The information on the design of the suppression pool is reviewed to familiarize the reviewer with the expected temperature histories, depth of fission product entry expected during postulated accidents, and potential leakage paths through drywell penetrations. 4. Testing and Technical Specifications The details of the applicant's proposed preoperational tests and, at the operating license stage, the surveillance requirements are reviewed to ensure that the pool depth and amount of leakage bypassing the pool are maintained consistent with the assumptions used in assessing the pool's effectiveness in fission product cleanup. Review Interfaces:4 EMCB also reviews the drywell or containment spray systems for which fission product cleanup credit is claimed as part of its primary review responsibility for SRP Section 6.5.2. In addition, the EMCB will coordinate other branches' evaluations that interface with the overall review of the system as follows: 1. The Containment Systems and Severe Accident Branch (SCSB) reviews containment leakage assumptions as part of its primary review responsibility for SRP Section 6.2.1.1.C. 2. The SPLB reviews the engineered safety feature atmosphere cleanup systems as part of its primary review responsibility for SRP Section 6.5.1. II. ACCEPTANCE CRITERIA The acceptance criteria for the fission product cleanup function of the suppression pool are based on the relevant requirements of the following regulations: A. General Design Criterion 41 (Ref. 1) as it relates to the control of fission products 5 following postulated accidents. 6.5.5-3 DRAFT Rev. 1 - April 1996 B. General Design Criterion 42 (Ref. 2) as it relates to the periodic inspections of 6 engineered safety features. C. General Design Criterion 43 (Ref. 3) as it relates to the periodic functional testing of 7 engineered safety features. Where it can be shown to be in compliance with these criteria, the suppression pool may be given appropriate
