核应急决策辅助系统极为重要，机组内设备损坏情况、事故扩大趋势和应急干预措施可行性的评估对于事故后决策有重要作用.在事故评价方面，传统的模拟机和实时信息系统各有局限性，事故后不能充分发挥应急辅助决策的作用.通过结合二者的优点，开展基于在线仿真系统的事故评价和预测的技术方案研究，可以在事故瞬态时提供精确的三维展示、演变趋势预测和干预措施仿真推演功能，以支持采取科学有效的应急手段.
Nuclear emergency auxiliary decision-making system is important, and the evaluation about equipment damage situation within the unit, expansion trend of accident, feasibility of emergency intervention plays important roles in post-accident decision-making. In terms of accident evaluation, traditional simulator and real-time information system have their own limitations, which can not fully assist emergency decision-making after the accident. By combining advantages of the two and studying technical solutions for accident evaluation and prediction based on online simulation systems, this research provides accurate 3D display, evolutionary trend prediction and simulation deduction of intervention measures to support making scientific and effective emergency decision.
