摘要
以国际研究焦点,欧洲先进示范铅冷快堆ALFRED(European advanced demonstration lead cooled fast reactor)为模型,采用纯铅作为冷却剂,在ALFRED堆芯设计参数的基础上构建全堆芯中子运输模型,进行蒙特卡洛模拟计算。在不考虑可燃毒物与控制棒的前提下,研究反应堆冷却剂温度及燃料棒尺寸变化对反应堆有效增殖因数k值的影响,得到不同燃料棒尺寸与不同反应堆冷却剂温度下的k值并分别作图,模拟实验结果表明:随着燃料棒棒径的增加,k值变化曲线斜率先增加后逐步减小;随着反应堆温度的升高,k值逐渐下降,结果与实际值较符合。
Based on the international research focus,ALFRED(European advanced demonstration lead cooled fast reactor)is used as the model,pure lead is used as the coolant,and the whole core neutron transport model is constructed on the basis of the design parameters of ALFRED core,and Monte Carlo simulation calculation is carried out.Without considering burnable poison and control rod,the effect of reactor coolant temperature and fuel rod size change on the effective multiplication factor k value of reactor was studied.The k value of different fuel rod size and different reactor coolant temperature was obtained and plotted respectively.The simulation results showed that,with the increase of fuel rod diameter,the slope of k value curve first increased and then decreased gradually.With the increase of reactor temperature,k value decreased gradually,and the result was in good agreement with the actual value.
