Establishment of the hazard reduction methodology to be taken into account for safety assessment during decommissioning of nuclear facilities

This paper is to establish the hazard reduction methodology for decommissioning of nuclear facilities. There are radiological and non-radiological hazards during decommissioning of nuclear facilities. Based on a review of industrial methods and requirements of decommissioning safety, a method of hazard reduction has been designed and a mathematical method of cost estimation has been developed using a parametric method.
