摘要
分别采用了代价—利益、代价—效益、多属性效用分析等方法对核燃料元件厂化工转化(ADU工艺)生产线出料场所防护改进方案进行了最优化分析,3种不同的分析方法得出的分析结果一致。通过实施改造能够显著降低化工生产线(ADU工艺)还原岗位出料场所的放射性气溶胶浓度,进一步改善场所作业环境,提高操作人员的职业健康水平。
The protection improvement solutions about the discharge position of the conversion production line （ ADU technology） in the nuclear fuel element plant were optimized analyzed by using cost-benefit, cost-efficiency and multi-attribute utility analysis, respectively. The results coincided by using the three methods. Through the implementation of the transformation measures, the concentration of radioactive aerosol which came from the discharge position of the reduction post in the conversion production line （ADU technology） was decreased. The work environment was further improved, and the occupational health level of the operators was raised.
