| Abstract: | In this paper, a seed assembly model with integral type burnable poison of SCFR-M has been established.It calculated and analyzed the neutronics parameters of seed assembly with different materials,mass fractions of poison and layouts. After considering the distortion of power distribution of the assembly,the reactive suppression at the beginning of life and the residual absorption penalty in the end of life,it selected the most appropriate layout arrangement of burnable poison.The conclusion shows that Er2O3 in Scheme 4 results in the best neutronics parameters. |
