te the evaluations of with other branches those 31 evaluations that interface with the overall review of the system, as follows: 32 33 a. The Containment Systems and Severe Accident Branch (CSB)(SCSB) evaluates 34 the containment pressure response and mixing fractions, verifies positive pressure periods, and determines containment leakage rates as part of its primary review responsibility for Standard Review Plan (SRP) Sections 6.2.1 and 6.2.6. 35 b. SCSB also has responsibility for evaluating the pressure transient in the secondary containment to verify secondary containment region pressures after a design basis accident and for reviewing bypass leakage paths as part of its primary review responsibility for SRP Section 6.2.3.36 The Auxiliary Systems Branch (ASB) reviews the ventilation system used to control fission products and the capability to maintain a negative pressure during accident conditions as part of its primary review responsibility for SRP Sections 9.4.1 through 9.4.5.37 DRAFT Rev. 3 - April 1996 6.5.3-4 c. The Mechanical Engineering Branch (MEB)(EMEB) reviews the seismic design 38 and quality group classifications for ventilation systems as part of its primary review responsibility for SRP Sections 3.2.1 and 3.2.2. d. The Mechanical Engineering Branch (EMEB) also has responsibility for evaluating the structural design of the ventilation system.39 The acceptance criteria for the review of those sections and the methods of application are contained in the referenced SRP section of the corresponding primary review branch. II. ACCEPTANCE CRITERIA In establishing the model for estimating the radiological consequences of a design basis loss-of-coolant accident and determining the acceptability of the fission products control systems and structures, AEBSPLB uses acceptance criteria based on the requirements of the following 40 regulations: A. General Design Criterion 41 (GDC 41) (Ref. 1) as it relates to the containment 41 42 atmosphere cleanup system being
