to detect and annunciate or has provided dual instrumentation on redundant MCES trains to detect, annunciate, and effect control measures to prevent the buildup of potentially explosive mixtures. This review is conducted by ETSBSPLB concurrently with its review as outlined in SRP Section 11.3 for a gaseous radioactive waste management system. ETSBSPLB will also determine if 10.4.2-5 DRAFT Rev. 3 - April 1996 the applicant's design includes adequate provisions to stop continuous leakage paths after an explosion. 4. ETSB reviews the quality assurance for the design, construction, and operational phases for the MCES according to the guidelines of Regulatory Guides 1.123 and 1.33 (Refs. 4 and 5). Exceptions are transmitted to QAB, which has primary responsibility under SRP Sections 17.1 and 17.2.26 For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.27 IV. EVALUATION FINDINGS ETSBSPLB verifies that sufficient information has been provided and that the review is adequate to support conclusions of the following type, to be included in the staff's safety evaluation report (SER): The main condenser evacuation system includes equipment and instruments to establish and maintain condenser vacuum and to prevent an uncontrolled release of radioactive material to the environment. The scope of our review included the system capability to transfer radioactive gases to the gaseous waste processing system or ventilation exhaust
