ive formal design verification by interdisciplinary or multi-organizational teams and those which can be reviewed by a single individual (a signature and date is acceptable documentation for personnel certification). Design documents subject to procedural control include, but are not limited to, specifications, calculations, computer programs, system descriptions, SAR when used as a design document, and drawings including flow diagrams, piping and instrument diagrams, control logic diagrams, electrical single line diagrams structural systems for major facilities, site arrangements, and equipment locations. Specialized reviews should be used when uniqueness or special design considerations warrant. d. The responsibilities of the verifier, the areas and features to be verified, the pertinent considerations to be verified, and the extent of documentation are identified in procedures. 20. The following provisions are included if the verification method is only by test: a. Procedures provide criteria that specify when verification should be by test. b. Prototype, component or feature testing is performed as early as possible prior to installation of plant equipment, or prior to the point when the installation would become irreversible. c. Verification by test is performed under conditions that simulate the most adverse design conditions as determined by analysis. 17.5-19 Revision 1 – August 2015 21. Procedures are established to ensure that verified computer codes are certified for use and that their use is specified. 22. Control of computer programs used for design analysis includes the following: a. Computer program acceptability is pre-verified or the results verified with the design analysis for each application. b. Computer programs are controlled to ensure that changes are documented and approved by authorized personnel. 23. Design and specification changes, including field changes, are subject to the same design controls that were applicable to the original
