th Regulatory Guides The information and requirements contained in this appendix supersede those in the October 1973 version of Regulatory Guide 1.67 and the May 1973 version of Regulatory Guide 1.48. Regulatory Guides 1.124 and 1.130 on Class 1 linear 165 and Class 1 plate and shell component support structures are to be supplemented by this appendix. DRAFT Rev. 2 - April 1996 3.9.3-26 TABLE I Allowable Service Stress Limits for Specified Service Loading Combinations for ASME Class 1, 2, and 3 Components and Component Supports, and Class CS Core Support Structures 166 System Service Service Stress Plant Event Operating Conditions Loading Combination Limit 2 1,4 ______________________________________________________________________________________________________ 1.

LOCA + SSE Faulted Sustained Loads + LOCA + SSE D3 NOTE: The appropriate method of combination is subject to review and evaluation. Refer to Section 1.2. 1 Refer to Table II for definition of terms 2 In addition to meeting the specified service stress limits for given load combinations, operability and functional 3 capability must also be demonstrated as discussed in subsection 2.0 of this appendix and in SRP Section 3.10. These events must be considered in the pipe stress analysis and pipe support design process when specified in the 4 ASME Code-required Design Specification. The Design Specification shall define the load and specify the applicable Code Service Stress Limit. For clarification, it should be noted that the potential for water hammer and water (steam) hammer occurrence should also be given proper consideration in the development of Design Specifications.
