Content:
minimum radioiodine removal efficiency of the charcoal adsorbers in the standby gas treatment system (SGTS) filter trains and the maximum time for the SGTS to draw a specified negative pressure in the secondary containment may be verified by the ITAAC for the SGTS. The minimum radioiodine removal efficiency of the charcoal adsorbers in the control room and TSC ventilation 14.3.8-5 DRAFT Rev. 0 - April 1996 system filter trains may be verified by the ITAAC for the HVAC systems. Capability of the main steam system to maintain structural integrity in an safe-shutdown earthquake (SSE) may be verified by the ITAAC for the turbine main steam system. Capability of the off-gas system to withstand an internal hydrogen explosion may be verified by the ITAAC for the off-gas system. The applicant should provide a radiological analysis table in DCD Tier 2 Section 14.3 that should be used to ensure that the most important, though not necessarily all, of the key parameters in the accident dose analyses are addressed in Tier 1. Site Parameters PERB is responsible for ensuring that the meteorological dispersion values assumed in various accident analyses are identified as bounding parameters for a site in Tier 1 section for site parameters. These parameters should be specified for the EAB and LPZ at appropriate time intervals for the standard design. The reviewer should ensure that the site parameters in Chapter 2 of DCD Tier 2 are consistent with Tier 1. The parameters are used to evaluate the suitability of a site for the design, and must be demonstrated as part of an early site permit or as part of an application for a combined license. III. REVIEW PROCEDURES 1. Follow the general procedures for review of Tier 1 contained in the Review Procedures section of SRP Section 14.3. Ensure that the DCD is consistent with Appendix A to SRP Section 14.3. Review responsibilities may be consistent with those in Appendix B to SRP Section 14.3. 2. Ensure that all Tier 1 information is
