this SRP section because the reviewer verifies that adequate radiation protection and protection from hazardous chemical releases will be provided to permit access to and occupancy of the control room under accident conditions. Regulatory Guides 1.52, 1.78, and 1.95 present methods acceptable to the staff for meeting control room occupancy protection requirements. Meeting the requirements of GDC 19 provides assurance that adequate protection will be maintained to permit access to and occupancy of the control room under accident conditions.43 6.4-9 DRAFT Rev. 3 - April 1996 4. Compliance with 10 CFR 50.34(f)(2)(xxviii) requires the evaluation of potential pathways for radioactive materials that may lead to problems related to control room habitability under accident conditions. The requirements 10 CFR 50.34(f)(2)(xxviii) apply to this SRP section because the review evaluates issues involving isolation of the control room, pressurization to prevent inleakage, filtration of the control room air, and location of ventilation intakes. Collectively, these criteria are designed to mitigate the radiological consequences of accidents in the control room. Meeting the requirements of 10 CFR 50.34(f)(2)(xxviii) provides assurance that, in the event of an accident, radiation doses to operators will not exceed acceptable limits and consequently prevent operators from performing required functions.44 III. REVIEW PROCEDURES The reviewer selects and emphasizes aspects of the areas covered by this review plan as appropriate for a particular case. The judgment on areas to be given attention and emphasis in the review is based on an inspection of the material presented to see whether it is similar to that recently reviewed for other plants and whether items of special safety significance are involved. 1. Control Room Emergency Zone The reviewer verifies that the control room emergency zone includes the areas identified in subsection II.1 of this SRP section. The emergency zone should be
