Issues Identified in Trouble Event Analysis concerning Maintenance Management in Nuclear Power Plants

Abstract

We extracted the problems related to maintenance management by applying the perspective of 98 PSF items of the GAP-W type PSF reference list for factor analysis of disclosed cases of trouble at nuclear power plants (NUCIA database, Japan Nuclear Safety Institute). Also we examined good practices in contents of education and training courses implemented in relation to maintenance of electric utilities that were published in peer review reports, and we extracted items needing attention from them. By considering the problems comprehensively that we extracted from the factor analysis and the items that we extracted from the good practices research, we derived seven issues for future consideration for maintenance management. I. “Efficiency of training by utilizing the difference in skill type.” II. “Establishment of principles of maintenance management, as reflected in maintenance education and maintenance activities.” III. “Setting definitions of abnormal experiences, and introducing them into maintenance training.” IV. “Fostering a suitable behavior-criteria in maintenance work.” V. “Enhancing the ability to avoid easily overlooked pitfalls in work carried out.” VI. “Education and training for increased awareness of abnormalities, and securing and training of educational staff.” VII. “Development of an information support system within the maintenance work site.”
