Analysis of Environmental Influence in Maximum Hypothetical Accident of CFBR-II Reactor

Institute of Nuclear Physics and Chemistry, China Academy of Engineering Physics, Mianyang, Sichuan, 621900, China

摘要: 根据国外快中子增殖反应堆型最大假想事故的确定原则,计算分析了中国快中子增殖反应堆(CFBR-II堆)的最大假想事故的规模及源项。根据对释放模式、大气扩散模式和个人有效剂量来源的分析,在保守假设的情况下,计算得到距堆厅典型位置的公众和工作人员的个人有效剂量。与国家标准进行比较,发生最大假想事故时,对公众和工作人员不需要采取服碘、隐蔽和撤离等应急措施,事故应急处于应急待命水平。

Abstract: Scale of accident and data of radioelement on CFBR-II reactor are calculated and analyzed based on the principle used in its determination in the fast pulsed reactors in foreign countries. According to analysis of gas-dispersion mode, aerodynamic diffusion mode and source of individual effective dose, the individual effective dose of public and operator on the representative position in a conservative estimate is obtained. Compared with the national standards, it is not necessary to take emergency measurements such as for the public and operators to take iodine, shield and evacuate when maximum hypothetical accident does occurred.
