Job Analysis of Maintenance Mechanic Position for the Nuclear Power Plant Maintenance Personnel Reliability Model.

摘要

The report is one of a series planned to describe the results of a program to define, develop, validate, and disseminate a methodology for the quantitative prediction of human reliability in the conduct of maintenance tasks in nuclear power plants (NPPs). An analysis was performed of the job of maintenance mechanics in nuclear power plants in order to provide a part of the information required for modeling nuclear plant maintenance activities. It is believed that such a model would provide substantial insights into the various human, equipment, and environmental factors likely to affect reliability of maintenance personnel, and thereby suggest and allow evaluation of standards, design changes or other modifications to improve reliability and minimize public risk. The task list method of job survey was selected because the approach minimizes data acquisition costs, interferes minimally with the work of job incumbents, is comprehensive and objective, provides quantitative data, and seemed highly appropriate for achieving the goals of the work. In collaboration with supervisory personnel at BWR and PWR nuclear power plants, a comprehensive list of 107 tasks performed by maintenance mechanics was developed. The tasks were grouped within six generic work functions: remove and install, test and repair, inspect and perform preventive maintenance, miscellaneous, communication, and report preparation. The lists were then assembled into appropriate questionnaire form. The results of the survey are reported in this study.
