assurance is achieved by identifying the critical characteristics of the item and verifying their acceptability by inspections, tests, or analyses performed by the purchaser or third-party dedicating entity after delivery, supplemented as necessary by one or more of the following: commercial grade surveys; product inspections or witness at holdpoints at the manufacturer’s facility, and analysis of historical records for acceptable performance.” An acceptable set of fundamental requirements for this process is described in IEEE 7-4.3.2, Section 5.3.2, and guidance given in Annex D (Informative) of the standard. This standard is endorsed in Reg. Guide 1.152, Rev. 1. In this guidance, the qualification process is accomplished by comparing the commercial-grade item to the design criteria of the standard. This standard allows the use of engineering judgment for the acceptance of existing software, and the use of compensating factors to substitute for missing elements of the software development process. These provisions should not be interpreted to permit unsupported subjectivity in the acceptance of existing software. The guidance provided herein for the review of newly developed software provides technical background pertinent to evaluating the use of the engineering judgment and compensating factors provisions. The standard requires the acceptance, and its basis, to be documented and maintained with the qualification documentation. In order to demonstrate reasonable assurance, the acceptance process for most PDS can be expected to comprise a variety of technical activities conducted in significant detail. Guidance on these activities has been provided in EPRI TR-106439. The NRC has issued a safety evaluation report (SER) on the EPRI guideline in which it determined that “TR-106439 contains an acceptable method for dedicating commercial grade digital equipment for use in nuclear power plant safety applications.” If the guidance in EPRI TR-106439 is applied in
