Abstract:
For the last three years about fifty experts have been working in the international IAEA project "Evaluation and Demonstration of Safety during Decommissioning of Nuclear Facilities (DeSa Project)" on; (i) the establishment of a harmonized general safety assessment methodology for decommissioning; on (ii) the development of recommendations for a regulatory review process of such safety assessments; (iii) development of recommendations on the application of a graded approach to performance and review of safety assessment, which ensures that the extent of the safety assessment is commensurate which the risks posed by the facility and the proposed decommissioning activities, and finally (iv) the application of the new methodologies to three test cases with different complexities and hazard potentials ・a nuclear power plant, a research reactor and a nuclear laboratory.
This paper provides an overview on current status of the DeSa project activities, and their application to the development of the Research Reactor Test Case. The DeSa project results are envisaged to be summarized at the 4th Joint DeSa meeting in October 2007, where a potential follow-up project will be also discussed.
