locations and efficiencies, system redundancy, actuation signals, time to reduce region pressures below atmospheric, placement of ducting (see SAR Sections 6.2.3, 6.5.1, and 6.5.3). 6.5.3-3 Revision 3 - March 2007 The reviewer is responsible for determining that each system can perform its functions as claimed to reduce fission product release following a postulated design basis accident. Knowledge of fission products removal systems is necessary for modeling the system for the dose calculation. D. General design characteristics- e.g., negative pressure during normal operation, free volumes and mixing regions, and leakage rates (see SAR Sections 6.2.3, 6.5.3, and 9.4). Knowledge of these parameters is necessary for developing the mathematical model for dose calculations. 3. Other Fission Product Control Systems. The ventilation systems used to control fission products and the capability to maintain a negative pressure during accident conditions (see SAR Sections 9.4.1 through 9.4.5). 4. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant's proposed ITAAC associated with the structures, systems, and components (SSCs) related to this SRP section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses, and Acceptance Criteria." The staff recognizes that the review of ITAAC cannot be completed until after the rest of this portion of the application has been reviewed against acceptance criteria contained in this SRP section. Furthermore, the staff reviews the ITAAC to ensure that all SSCs in this area of review are identified and addressed as appropriate in accordance with SRP Section 14.3. 5. COL Action Items and Certification Requirements and Restrictions. For a DC application, the review will also address COL action items and requirements and restrictions (e.g., interface requirements and site parameters). For a COL application referencing a DC, a
