ABSTRACT A unified approach in performing a failure mode, effects and
criticality analysis (FMECA) is described. This procedure provides a
technique for performing a thorough analysis that can identify
engineering problem areas and failure modes at specific plant levels,
and contribute to the validity of design review process. It provides
formats for documenting plant/equipment operating characteristics so
that failure modes can readily be identified with a functional
characteristic. In addition, it gives an analytical technique that can
identify necessary corrective action with which top management can make
critical decisions

    ABSTRACT: Planning the development, use and regulation of computer systems in nuclear reactor protection systems in such a way as to enhance reliability and safety is a complex issue. This report is one of a series of reports from the Computer Safety and Reliability Group, Lawrence Livermore National Laboratory, that investigates different aspects of computer software in reactor protection systems. There are two central themes in the report. First, software considerations cannot be fully understood in isolation from computer hardware and application considerations. Second, the process of engineering reliability and safety into a computer system requires activities to be carried out throughout the software life cycle. The report discusses the many activities that can be carried out during the software life cycle to improve the safety and reliability of the resulting product. The viewpoint is primarily that of the assessor, or auditor. iv v CONTENTS 1. Introduction .............................

    ABSTRACT: The feasibility of integrating failure modes and effects analysis (FMEA) and sneak circuit analysis (SCA) into a comprehensive reliability analysis technique is examined especially from the perspective of automation. FMEA looks at a system's strengths and weaknesses; SCA looks for latent circuit conditions which may lead to unplanned or unexpected modes of operation. The goals of the two techniques complement each other and their combination results in a more comprehensive analysis than either technique alone can achieve. The rich collection of heuristics used in SCA can be applied to design validation and also used as guidelines at various stages of system design. At both the functional level and the component level, the combined analysis is done using the same circuit representation as for the SCA and for the FMEA, and draws on the same database
