摘要
作为核燃料循环过程中一种兼具辐射危害和化学毒性的中间产物,UF_6的泄漏事故,特别是事故的环境评价技术越来越受到人们的重视。SAFUIT/UF_6是专门针对此类事故的环境评价模型,目前已经开展了初步的验证工作。根据1987年法国UF_6释放实验条件,对SAFUIT/UF_6模型计算结果进行了误差分析,并与HGSYSTEM/UF_6模型进行了对比。初步认为SAFUIT/UF_6模型可准确地模拟UF_6扩散。此外,SAFUIT/UF_6模型在某设施核事故应急评价系统中也得到了应用。
As an important intermediate in the nuclear fuel cycle process, Uranium Hexafluoride （UF6 ）has both the chemical toxicity and radiation hazard. This paper introduced the verification progress of SAFUIT/UF6 model, according to the condition of France experiments in 1987. SAFUIT/UFs calculation errors were analyzed and compared with HGSYSTEM/UF6 model. These results confirmed that SAFUIT/UF6 model was suite in modeling UF6 dispersion. In addition, this paper also introduced the application of SAFUIT/UF6 in a factory＇s nuclear accident emergency assessment system.
