Content:
through drywell penetrations is obtained as a product of the review under SRP Section 6.2.1.1.C. If B is the bypass fraction and DF is the time-integrated pool decontamination factor, then the overall decontamination, D, to be used for accident dose calculations, may be taken as: DF D = 1 + B(DF-1) The reviewer should clearly distinguish that fraction of B, which may be further treated by the standby gas treatment system, from that fraction of B which also bypasses the secondary containment building. 3. Other Containment Atmosphere Cleanup Systems Drywell or containment spray systems for which fission product cleanup credit is claimed are reviewed under SRP Section 6.5.2, and credit for both suppression pool and spray cleanup can be given as a result of the separate reviews. DRAFT Rev. 1 - April 1996 6.5.5-6 4. Technical Specifications The technical specifications are reviewed to ensure that they require periodic inspection to confirm suppression pool depth and surveillance tests to confirm drywell leak tightness, consistent with the bypass fraction used in computing the overall decontamination. For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.14 IV. EVALUATION FINDINGS The reviewer verifies that sufficient 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
