Content:
containment spray system is determined from the following equation (Reference 415) : 38 where H is the effective iodine partition coefficient, V is the volume of liquid in s containment sump and sump overflow, and V is the containment building net c free volume less V . s The maximum decontamination factor is 200 for elemental iodine. The effectiveness of the spray in removing elemental iodine shall be presumed to end at that time, post-LOCA, when the maximum elemental iodine DF is reached. Because the removal mechanisms for organic iodides and particulate iodines are significantly different from and slower than that for elemental iodine, there is no need to limit the DF for organic iodides and particulate iodines. 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.39 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided by the applicant and that the review and calculations support conclusions of the following type, to be included in the staff's safety evaluation report: The concept upon which the proposed system is based has been demonstrated to be effective for fission product removal and retention under postaccident conditions. The proposed system design is an acceptable application of this concept. The system 6.5.2-15 DRAFT Rev. 3 - April 1996 provides suitable redundancy in components and features so that its safety function can be accomplished assuming a single
