An approach to the semi-quantitative assessment model on human errors for decommissioning of nuclear facilities

• The assessment model on human errors for decommissioning of nuclear facilities was proposed.
• The structure of the model was systematically established.
• The method of the model was quantitatively designed.
• Feasibility study of the method was demonstrated.

This paper is to suggest the assessment model on human errors for decommissioning of nuclear facilities. On the basis of evaluation items, the structure of the model was systematically established and the method for the model was quantitatively designed. The categories of evaluation items consist of ‘psychological’, ‘physical’, ‘man-machine’, and ‘environmental’. The method is composed of scaling and weighting factors. Feasibility study of the method was accomplished by applying a scenario.
