ASSESSMENT OF PROLIFERATION RESISTANCE OF DUPIC FUEL CYCLE BY INPRO METHODOLOGY

The IAEA has launched an International Project on Innovative Nuclear Reactors and Fuel Cycle (INPRO) in 2000, and the INPRO methodology is developed to assess the future innovative nuclear energy system. Proliferation resistance is one of goals to be satisfied for the sustainability of future nuclear energy systems. The INPRO methodology in proliferation resistance area is here reviewed, and evaluation metrics are suggested. Korea is developing the DUPIC fuel cycle technology to reuse the spent PWR fuel in CANDU reactors without separating stable fission products. The proliferation resistant characteristics of the DUPIC fuel cycle are assessed by using the developed INPRO methodology and the evaluation metrics. The proposed assessment procedure and the evaluation metrics for the demonstration study on DUPIC can be utilized as a reference for assessment of the proliferation resistance of a future nuclear energy system.
