Description and Design Drawings The reviewer should see that the fuel system description and design drawings are complete enough to provide an accurate representation and to supply information needed in audit evaluations. Completeness is a matter of judgment, but the following fuel DRAFT Rev. 3 - April 1996 4.2-10 system information and associated tolerances are necessary for an acceptable fuel system description: Type and metallurgical state of the cladding Cladding outside diameter Cladding inside diameter Cladding inside roughness Pellet outside diameter Pellet roughness Pellet density Pellet resintering data Pellet length Pellet dish dimensions Burnable poison content Insulator pellet parameters Fuel column length Overall rod length Rod internal void volume Fill gas type and pressure Sorbed gas composition and content Spring and plug dimensions Fissile enrichment Equivalent hydraulic diameter Coolant pressure Design Specific Burnup Limit49 The following design drawings have also been found necessary for an acceptable fuel 50 system description: Fuel assembly cross section Fuel assembly outline Fuel rod schematic Spacer grid cross section Guide tube and nozzle joint Control rod assembly cross section Control rod assembly outline Control rod schematic Burnable poison rod assembly cross section Burnable poison rod assembly outline Burnable poison rod schematic Orifice and source assembly outline C. Design Evaluation The methods of demonstrating that the design bases are met must be reviewed. Those methods include operating experience, prototype testing, and analytical predictions. Many of these methods will be presented generically in topical reports and will be incorporated in the Safety Analysis Report by reference. 4.2-11 DRAFT Rev. 3 - April 1996 1. Operating Experience Operating experience with fuel systems of the same or similar design should be described, including the maximum burnup experience . When adherence to 51 specific
