ontainment | sump design (as part of SRP Section 6.2.2), 6.5.2-3 Rev. 3 - December 2005 - the hydrogen mixing function of the containment spray system (as part of SRP Section 6.2.5), and - the general guidance on the initial plant test program (as part of SRP Section 14.2). | The acceptance criteria and review procedures are given in the referenced SRP sections for the areas of review identified above. II. ACCEPTANCE CRITERIA The acceptance criteria for the fission product cleanup function of the containment spray system are based on meeting the relevant requirements of the following regulations: A. General Design Criterion (GDC) 41 as it relates to containment atmosphere cleanup systems designed to control fission product releases to the reactor containment following postulated accidents. B. GDC 42 as it relates to containment atmosphere cleanup systems designed to permit appropriate periodic inspections. C. GDC 43 as it relates to containment atmosphere cleanup systems designed for appropriate periodic functional testing. D. 10 CFR 52.47(a)(1)(vi) provides the requirement for ITAAC for design certification reviews. | | E. 10 CFR 52.97(b)(1) provides the requirement for ITAAC for combined license reviews. | The specific criteria necessary to meet the relevant requirements of GDC 41, 42, and 43 include: 1. Design Requirements for Fission Product Removal The containment spray system should be designed in accordance with the requirements of ANSI/ANS 56.5 (Reference 14), except that the requirements for any spray additive or | other pH control system in this reference need not be followed. a. System Operation The containment spray system should be designed to be initiated automatically by an appropriate accident signal and transferred automatically from the injection mode to the recirculation mode to ensure continuous operation until the design objectives of the system have been achieved. In all cases, the operating period should not be less than 2 hours. Additives to
