CFR Title: 

Content:
olant pressure boundary shall be specified, including reactor internals and core support structures. The section of the applicant's SAR which pertains to transients will be acceptable if the transient conditions selected for equipment fatigue evaluation are based upon a conservative estimate of the magnitude and 3.9.1-2 Rev. 2 - July 1981 frequency of the temperature and pressure conditions resulting from those transients. To a large extent the selection of these specific transient conditions is based upon engineering judgment and experience. Some guidance on the selection of these transients and combinations can be found in References 8 and 9. Transients and resulting loads and load combinations with appropriate specified design and service limits must provide a complete basis for design of the reactor coolant pressure boundary for all conditions and events expected over the service lifetime of the plant. 2. To meet the requirements of 10 CFR Part 50, Appendix B and GOC 1, a list of computer programs that will be used (preferably programs which are I recognized and widely known) in dynamic and static analyses to determine the structural and functional integrity of seismic Category I Code and non-Code items, and the analyses to determine stresses-shall be provided. For each program the following information shall be provided to demonstrate its applicability and validity: a. The author, source, dated version and facility. b. A description, and the extent and limitation of its application. c. The computer program solutions to a series of test problems which shall be demonstrated to be substantially similar to solutions obtained from any one of sources 1 through 4, and source 5: (1) hand calculations (2) analytical results published in the literature (3) acceptable experimental tests (4) by an MEB acceptable similar program (5) the benchmark problems prescribed in Reference 10. A summary comparison of the solution obtained by using sources 1 through 4 shall be
