Abstract: Taking domestic uranium processing and fabrication facilities (hereinafter referred to as factory A) for example, the author analyzes the factors influencing the optimization of public dose constraint value of uranium processing and fabrication facilities. Using methods of engineering judgment and multiple attribute function analysis, factors including individual effective dose, the public collective effective dose, waste management cost and public reactions of the critical population group are considered to calculate the optimal values of public dose constraint of uranium processing and fabrication facilities weighted by different influencing factors, then the optimal value and maximum efficiency function curve of dose constraint value is calculated using least square method. Finally, the average value of optimal target management of uranium processing and fabrication facilities was calculated by adopting of the weighted average method. Strictly speaking, this value depends on various factors. So this is not “optimal solution”, can only be described as a compromised “satisfactory solution”.

Key words: uranium processing and fabrication facilities, dose constraints, optimization analysis
