The Design Methodology and the Safety Concept of the Surface Disposal Facility for the Belgian Category A Waste at Dessel

The paper describes the design methodology that ONDRAF/NIRAS, the Belgian Agency for Radioactive Waste and Enriched Fissile Materials, has developed and applied in the framework of the surface disposal facility for category A waste, i.e. solid conditioned low level radioactive waste that contains a limited amount of long lived radionuclides, at Dessel. The proposed disposal facility supporting the submitted construction and operation license application [1, 2] is also presented.
