follows: any chemical additive storage requirements, materials compatibility of the long-term containment sump and recirculation spray solutions, and organic material decomposition including formation of organic iodides as part of SRP Sections 6.1.1 and 6.1.2, the heat removal and hydrogen mixing function of the containment spray system and the containment sump design as part of SRP Sections 6.2.2 and 6.2.5. The acceptance criteria for the review and the methods of application are contained in the referenced SRP sections. II. ACCEPTANCE CRITERIA The acceptance criteria for the fission product cleanup function of the contain- ment spray system are based on meeting the relevant requirements of the following regulations: A. General Design Criterion 41 (Ref. 1) as it relates to containment atmosphere cleanup systems being designed to control fission product releases to the reactor containment following postulated accidents. 6.5.2-2 Rev. 2 - December 1988 B. General Design Criterion 42 (Ref. 2) as it relates to containment atmosphere cleanup systems being designed to permit appropriate periodic inspections. C. General Design Criterion 43 (Ref. 3) as it relates to containment atmosphere cleanup systems being designed for appropriate periodic functional testing. Specific criteria necessary to meet the relevant requirements of General Design Criteria 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 Reference 4, except that requirements for any spray addi- tive 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 to be 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
