tion. Any referenced material must be readily available from a technical library. Copies of any referenced documents that are not readily obtainable from a technical library or the NRC Public Document Room, including proprietary reports, must be included with the documentation or provided upon request. The code documentation must be sufficiently detailed that a qualified engineer can understand the documentation without recourse to the originator as required of any design calculation that meets the design control requirements of Appendix B to 10 CFR Part 50, and the documentation requirement in Appendix K to 10 CFR Part 50. It is desirable that the documentation include the responses to requests for additional information, sorted according to the review issue so that it is easy to follow the entire review history for a single issue. The reviewer can help obtain this goal by issuing RAI’s organized by review issue. The documentation must include the following components: A. An overview of the evaluation model which provides a clear roadmap describing all parts of the evaluation model, the relationships between them, and where they are located in the documentation. B. A complete description of the accident scenario including plant initial conditions, the initiating event and all subsequent events and phases of the accident, and the important physical phenomena and systems and/or component interactions that influence the outcome of the accident. C. A complete description of the code assessment comprising a description of each assessment test, why it was chosen, success criteria, diagrams of the test facility that show the location of instrumentation that is used in the assessment, a code model nodalization diagram, and all code options used in the calculation. D. A determination of the code uncertainty for a sample plant accident calculation. (Appendix K models do not require a determination of the code uncertainty. E. A theory manual that is a self-contained
