REVIEW RESPONSIBILITIES Primary - Organization responsible for review of chemical engineering issues. | Secondary - Organization responsible for review of containment systems. | I. AREAS OF REVIEW The containment spray and the spray additive or pH control systems are reviewed to determine the fission product removal effectiveness whenever the applicant claims a containment atmosphere fission product cleanup function for the systems. The following areas of the applicant’s safety analysis report (SAR) relating to the fission product removal and control function of the containment spray system are reviewed. 1. Fission Product Removal Requirement for Containment Spray Sections of the SAR related to accident analyses, dose calculations, and fission product removal and control are reviewed to establish whether the applicant claims fission product scrubbing of the containment atmosphere for the mitigation of radiological consequences following a postulated accident. This review usually covers sections in SAR Chapters 6 and 15. 2. Design Bases The design bases for the fission product removal function of the containment spray system are reviewed to verify that they are consistent with the assumptions made in the accident evaluations in SAR Chapter 15. Rev. 3 - December 2005 6.5.2-2 3. System Design The information on the design of the spray system, including any subsystems and supporting systems, is reviewed to familiarize the reviewer with the design and operation of the system. The information includes: a. The description of the basic design concept; the systems, subsystems, and support systems required to carry out the fission product scrubbing function of the system; and the components and instrumentation employed in these systems. b. The process and instrumentation diagrams. c. Layout drawings (plans, elevations, isometrics) of the spray distribution headers. d. Plan views and elevations of the containment building layout. 4. Testing and Inspections The system
