Identification of human errors of commission using Sneak Analysis

Abstract

Sneak Analysis was adapted for use in identifying human errors of commission. Flow diagrams were developed to guide the analyst through a series of questions aimed at locating sneak paths, sneak indications, sneak labels, and sneak timing. An illustration of the application of this methodology in a nuclear environment is given and a computerized tool to support Sneak Analysis is described. A nuclear power plant loss of coolant accident is used as the example of sneak analysis of reactor safety. 8 figs
