摘要
紧凑式水泥固化装置在处理少量或零星放射性废液上具有装置灵活、经济等优势。为兼顾该装置轻便灵活和运行辐射安全要求,需精确了解相应的辐射分布情况,精准推算屏蔽配置需求,从而促进优化辐射防护设计。本文采用蒙特卡洛方法建立了紧凑式水泥固化装置的屏蔽计算模型,研究在不同运行工况下,操作人员工作区域的辐射场。以此为基础,按照××厂对个人剂量限值的要求,对紧凑式水泥固化装置进行了屏蔽设计,并推算出所需屏蔽体厚度。最后采用真实热料进行工程验证,测量数据表明屏蔽设计及计算保守合理,能保护操作人员的辐射屏蔽安全。
The compact cement curing device has the advantages of flexibility and economy in the treatment of small or sporadic radioactive waste liquids.In order to take into account the lightness and flexibility of the device and the radiation safety requirements for operation,it is necessary to accurately understand the corresponding radiation distribution and accurately calculate the shielding configuration requirements,thereby promoting the optimization of radiation protection design.In this paper,the Monte Carlo method is used to establish the shielding calculation model of the compact cement curing device,and the radiation field of the operator’s working area is studied under different operating conditions.Based on this,according to the personal dose limit requirement of XX factory,the shielding design of the compact cement-fixed device is carried out,and the required shielding thickness is calculated.Finally,the real hot material is used for engineering verification.The measurement data shows that the shielding design and calculation are conservative and reasonable,which can protect the radiation shielding safety of operators.
