Development of a checklist for evaluating maintenance, test and calibration procedures used in Nuclear Power Plants

Abstract

This report describes the process for developing a checklist to be used by United States Nuclear Regulatory Commission Office of Inspection and Enforcement (I and E) inspectors during their evaluation of maintenance, test and calibration procedures. The objective of the checklist is to aid inspectors in identifying procedural characteristics that can lead to human performance deficiencies. Five nuclear power plants were surveyed to obtain a sample of procedures and related information for human factors evaluation. Procedural deficiencies were identified. In addition, a human factors analysis of 988 LERs submitted during the period 1975 through 1978 was performed to identify the major categories of procedures-related personnel error. Checklist items aimed at correcting these errors were developed. The checklist and suggested methods of application are presented. A companion document, Procedures Evaluation Checklist for Maintenance, Test and Calibration Procedures, NUREG/CR-1369, SAND80-7054, describes the checklist and provides instructions for use by I and E inspectors.
