iv) specify whether the snubber was constructed to the rules of ASME Code Section III, Subsection NF, (v) state whether the snubber is used as a shock, vibration, or dual purpose snubber, and (vi) for snubbers identified as either dual purpose or vibration arrestor type, indicate if both snubber and component were evaluated for fatigue strength. III. REVIEW PROCEDURES The reviewer will select and emphasize material from the procedures described below,.as may be appropriate for a particular case. For each area of review, the following review procedures apply: 1. Loading Combinations, System Operating Transient, and Stress Limits The objectives in reviewing the loading combinations and stress limits employed by the applicant in the design of Code Class 1, 2, and 3 compo- nents, component supports, ahd Class CS core support structures are to confirm that the appropriate postulated events have been included, that the loading combinations (including system operating transients) and the designation of design and service stress limits are appropriate. The review conducted during the CP stage determines that the objectives have been addressed and are being implemented in the design by obtaining a commitment from the applicant that specific design criteria will be utilized. 3.9.3-7 Rev. 1 - July 1981 By checking selected Code required Design Documents such as Design Reports, Load Capacity Data Sheets, and related material, the OL stage review verifies that the design criteria have been utilized and that components have been designed to meet the objectives. To assure that these objectives are met, the review is performed as follows: a. The applicant's proposed design and service loadings, and combina- tions thereof, are reviewed for completeness and for. appropriate designation of corresponding design and service stress limits. b. The combination of design and service loadings, including procedures for combination, proposed by the applicant for each Code-constructed item are
