In addition to the guidelines applicable to specific systems, guidelines are provided for reactor facility siting, general component and system design, conduct of operations, initial test programs, accident analysis, technical specifications and quality assurance. For each reactor system, and for each of the general topical areas described above, the Design Guide recommends industry and NRC standards, codes and guides and the applicable portions of 10 CFR (including the General Design Criteria in 10 CFR 50, Appendix A) to be considered by the DOE reactor facility contractor. Many existing nuclear industry standards and codes and ysNRC Regulatory Guides, although written primarily for commerical power reactors, are also generally applicable to the design 6f certain Category II reactors. The Design Guide includes design guidelines which provide interpretations of the standards, codes, and guides in order to facilitate their application to Category II reactors. When criteria from existing standards, codes, and guides do not provide adequate guidance, the design guidelines include interim recommendations for the designer pending the development or approval of appropriate new standards, codes, and guides. Aided by the introductory guidance provided by the Design Guide, it remains for the designer to consult the appropriate referenced standards, codes, and guides in order to be f~lly appraised of all system design requirements. All of the applicable standards, codes, and guides that are recommended for consideration by the designer are available from the appropriate issuing organization. A program will be developed to periodically update and revise the Design Guide as necessary to reflect future standards, revisions and developments and to incorporate changes recommended by the Design Guide users. In this manner, the Design Guide will remain a timely standard reference for the designer and reviewer, alike.
