This document identifies guidelines that review high-integrity software requirements documents in nuclear power plants and addresses item 4 (Adequacy of System Functions and Commitments) of the seven review requirements for digital systems listed in NUREG-0800. The framework used for developing the guidelines was taken from the Nuclear Regulatory Commission Standard Review Plan, as well as Branch Technical Positions applicable to software-based digital systems. The topic areas include accuracy, functionality, reliability, robustness, maintainability, security, timing, and human-computer interaction. Checklists in accordance with IEEE Std 830 for use during software requirements reviews are also discussed.
This document provides descriptions of 45 failures that are linked to software requirements review guidelines listed in Volume I prepared under Contract NRC-00-037. The failure descriptions are "lessons learned" illustrating why specific software requirements guidelines are needed.
