REVIEW RESPONSIBILITIES Primary - Chemical Engineering Branch Secondary - Plant Systems Branch Radiation Protection Branch I. AREAS OF REVIEW The pressure suppression pool is reviewed under this plan only when the applicant claims credit for fission product scrubbing and retention by the suppression pool. The pressure suppression pool and the drywell, when considered as a barrier to the release of fission products, are reviewed to assess the degree to which fission products released during postulated reactor accidents will be retained in the sup- pression pool. Leakage paths that allow fission products to bypass the pool are identified and reviewed, and the maximum fractional bypass leakage is obtained, for use in the evaluation of radiological dose consequences. 1. Fission Product Control Requirements Sections of the applicant's safety analysis report (SAR) related to accident analyses, accident dose calculations, and fission product control are reviewed to establish whether or not fission product scrub- bing of the drywell or reactor compartment atmosphere is claimed or required for mitigation of radiological consequences following a postu- lated accident. 2. Design Bases The design bases for the fission product removal function of the suppres- sion pool and the drywell or reactor compartment are reviewed to verify that they are consistent with the assumptions made in the accident evaluations of SAR Chapter 15. Rev. 0 - December 1988 USNRC STANDARD REVIEW PLAN Stardard review plans are prepared for the guidance of the Office of Nuclear Reactor Regulation staff responsible for the review of applications to construct and operate nuclear power plants. These documents are made available to the public as part of the Commission's policy to inform the nuclear Industry and the general public of regulatory procedures and policies. Standard review plans are not substitutes for regulatory guides or the Commission's regulations and compliance with them is not required. The
