Research on Nuclear Facilities Decommissioning Engineering Support System Framework

Nuclear facilities decommissioning is complex system engineering. Many countries have been studying correlative computer technology and have developed some computer system to support nuclear facilities decommissioning. These systems can be used to quantify radioactive waste, to visualize radioactive inventory, to simulate the dismantling plan, to evaluate workload in radiation environments and to optimize the decommissioning plan. The paper analyzed several correlative researches of other countries and studied the actuality of 101 research reactor of China. Based on above results, the paper proposes and describes in detail a new framework of the Nuclear facilities Decommissioning Engineering Support system (NADES) which will serve the 101 reactor decommissioning project. The framework is also recognized by correlative experts.
