Abstract
The purpose of this paper is to cover human reliability analysis of the
Tehran research reactor using an appropriate method for the representation
of human failure probabilities. In the present work, the technique for human
error rate prediction and standardized plant analysis risk-human reliability
methods have been utilized to quantify different categories of human errors,
applied extensively to nuclear power plants. Human reliability analysis is,
indeed, an integral and significant part of probabilistic safety analysis
studies, without it probabilistic safety analysis would not be a systematic
and complete representation of actual plant risks. In addition, possible
human errors in research reactors constitute a significant part of the
associated risk of such installations and including them in a
probabilistic safety analysis for such facilities is a complicated issue.
Standardized plant analysis risk-human can be used to address these
concerns; it is a well-documented and systematic human reliability analysis
system with tables for human performance choices prepared in consultation
with experts in the domain. In this method, performance shaping factors are
selected via tables, human action dependencies are accounted for, and the
method is well designed for the intended use. In this study, in
consultations with reactor operators, human errors are identified and
adequate performance shaping factors are assigned to produce proper human
failure probabilities. Our importance analysis has revealed that human
action contained in the possibility of an external object falling on the
reactor core are the most significant human errors concerning the Tehran
research reactor to be considered in reactor emergency operating procedures
and operator training programs aimed at improving reactor safety.
