REVIEW RESPONSIBILITIES Primary - Materials and Chemical Engineering Branch (EMCB)1 Secondary - Plant Systems Branch (SPLB) 2 Emergency Preparedness and Radiation Protection Branch (PERB) 3 I. AREAS OF REVIEW The ice condenser system is reviewed to determine the fission product removal effectiveness whenever the applicant claims a containment atmosphere fission product cleanup function for the system. 4 The following areas of the applicant's safety analysis report (SAR) are reviewed: 1. Fission Product Removal Requirement for the Ice Condenser System Sections of the SAR related to accident analyses, dose calculations, and fission product removal and control are reviewed to establish whether or not fission product scrubbing of the containment atmosphere is required for mitigation of radiological consequences following a postulated accident. This review usually covers SAR Chapters 6 and 15. 2. Design Bases The design bases for the fission product removal function of the ice condenser system are reviewed to verify that they are consistent with the assumptions made DRAFT Rev. 4 - April 1996 6.5.4-2 in the accident evaluations of SAR Chapter 15. The methodology used in this SRP section is not intended for containment venting evaluation. Containment venting will be considered in the evaluation of ice condensers as fission product cleanup systems when the Commission approves the final guidance on containment venting. 3. System Design The information on the design of the ice condenser system important to its fission product removal function is reviewed to familiarize the reviewer with the design and post-accident functioning of the ice condenser. The information includes: a. The basic design concept, the systems, subsystems, and support systems required to carry out the fission product cleanup function of the ice condenser. b. Descriptions and figures from the SAR related to the time required to establish a steady flow of an air-steam-iodine mixture through the ice beds,
