sment of design and structural integrity of the supports. The review addresses three types of supports: plate and shell, linear, and component standard types. All the component supports of these three types are covered in this SRP section. Although classified as component standard supports, snubbers require special consideration due to their unique function. Snubbers provide no load path or force transmission during normal plant operations but function as rigid supports when subjected to dynamic transient loads. Component supports are those metal supports which are designed to transmit loads from the pressure-retaining boundary of the component to the building structure. The methods of analysis for calculating the responses of the reactor coolant pressure boundary supports resulting from the combination of LOCA and SSE events are reviewed in SRP Sections 3.6.2 and 3.9.2. 3.9.3-2 Rev. 1 - July 1981 In addition, the MEB will coordinate other branches evaluations that interface with the overall review of this SRP section as follows: The Equipment Qualifica- tion Branch (EQB) evaluates the operability of pumps and valves and judges the design criteria for pressure-relieving devices which may have an active function during and after a faulted plant condition against the requirements of the component operability assurance program as part of its primary review respon- sibility for SRP Section 3.10. The Auxiliary Systems Branch (ASB) verifies that the number and size of valves specified for the steam and feedwater systems have adequate pressure-relieving capacity as part of its primary review responsi- bility for SRP Section 10.3. The Reactor Systems Branch (RSB) verifies that the number and size of valves specified for the reactor coolant pressure boundary have adequate pressure-relieving capacity as part of its primary review responsi- bility for SRP Section 5.2.2. The Containment Systems Branch (CSB) reviews the applicant's analyses of subcompartment differential
