e that the code is adequate for analyzing the chosen scenario. 5. Uncertainty Analysis Uncertainty analyses are performed to confirm that the combined code and application uncertainty is less than the design margin for the safety parameter of interest when the code is used in a licensing calculation. Examples of safety parameters are peak cladding temperature (PCT), cladding oxidation thickness, departure from nucleate boiling ratio (DNBR), and critical power ratio (CPR). 6. Quality Assurance Plan The quality assurance plan covers the procedures for design control, document control, software configuration control and testing, and error identification and corrective actions used in the development and maintenance of the evaluation model. The program also ensures adequate training of personnel involved with code development and maintenance, as well as those who perform the analyses. II. ACCEPTANCE CRITERIA The acceptance criteria are based on meeting the requirements of the regulations in 10 CFR Part 50 that govern the evaluation models for the specific accident under consideration (e.g., 10 CFR 50.46 for a LOCA). The following sections discuss the specific criteria. 1. Documentation The submittal must identify the specific accident scenarios and plant configurations for which the codes will be used. The evaluation model documentation must be scrutable, 15.0.2-3 Initial Issuance - December 2005 complete, unambiguous, accurate, and reasonably self-contained. Consistent nomenclature must be used throughout the entire model documentation. 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
