Content:
is of the dynamic characteristics of components, such as doors, blowout panels, or sand plugs, that must open or be removed to provide a vent flow path, and the methods and results of components tests performed to demonstrate the validity of these analyses. The analytical procedure to determine the loss coefficients and inertia terms (L/A, m (ft )) for each vent flow path, and to predict the vent mass flow rates, is -1 -1 5 reviewed. The design pressure chosen for each subcompartment is also reviewed. Review Interfaces6 The SCSB will coordinate other branches' evaluations that interface with the overall review of 7 8 the containment subcompartments. 1. The Mechanical Engineering Branch (EMEB) and the Structural Engineering Branch 9 (SEB), as part of theirits primary review responsibility for SRP Sections 3.6.2, and 3.8.3, respectively,will review the break locations and dynamic effects of postulated pipe ruptures, and the mechanical and structural design of movable and stationary devices 10 provided for vent flow control in containment subcompartments. 11 2. The Civil Engineering and Geosciences Branch (ECGB) , as part of its primary review 12 responsibility for SRP Section 3.8.3, will review the structural design of movable and stationary devices provided for vent flow control in containment subcompartments.13 3. The Materials and Chemical Engineering Branch (EMCB) reviews those applications that propose to exclude dynamic effects of pipe ruptures, including localized pressurization effects and loads on component supports, as part of its primary review responsibility for SRP Section 3.6.3 (later).14 For those areas of review identified above as being reviewed as part of the primary review responsibility of other branches, the acceptance criteria and their methods of applications are contained in the referenced SRP sections of the corresponding primary branchidentified as the primary review responsibility of those branches. 15 II.
