Risk Assessment in a Chemical Storage Facility

A risk assessment was performed to assist in the evaluation of equipment improvements for a chemical storage facility. The risk assessment was accomplished through the use of several different methodologies e.g., fault tree analysis, event trees, and risk perspective techniques. The result of the study was a new alternative for a chemical storage facility. This new alternative eliminated the requirement for a large storage facility and reduced the capital project cost by over 10 million dollars.

Application of Fault Tree Analysis Technique to Predict Instrumentation System Failure and Define Problem Areas in a Nuclear Power Plant Containment Study

An application of the Fault Tree Analysis Technique to predict instrumentation and control system failure of a nuclear power plant containment isolation system is described in this paper. Because of the lack of a reliable data base, a qualitative failure assessment was made to define problem areas, determine the priority of failures of hardware, software and human interface units and their impact on the total system. This qualitative analysis may detect startling problem areas and may, also, reveal the effect of unit faults on specific systems not otherwise apparent.

An Integrated Approach to System Failure Effects

The failure modes and fault tree analysis techniques as used on spacecraft have been applied to a transport system study. A general approach to systems reliability has evolved and been applied to other systems. Based on an analysis of systems functional modes, the system level effects of component deviation from nominal are derived. A grouped tree analysis of these events facilitates the allocation of probabalistic reliability requirements and provides good visibility when fail-safe or similar conditions apply. The approach is not limited to hardware. Computer programs and other software can also be analysed and risks defined and minimised.
