基于 cosRMC 的新一代 PWR栅元和组件燃耗计算
Burnup Calculation of Next Generation PWR Cell and Assembly Based on cosRMC
摘要
Abstract
One important character of next generation PWR is fuel enrichment .Taking into account of fuel fabrication and burnup ,the 235 U enrichment in UO2 fuel is less than 5% ,and the content of fissile Pu in M OX fuel is also less than 6% in general in PWR . The enrichment in the next generation fuel is likely to exceed the existing standard and the average burnup is expected to reach 70 GW · d/tU ,w hich proposed new require‐ments for reactor calculation software .The fission reaction rate distribution ,neutron flux density distribution and nuclear number density with the burnup for the next gener‐ation PWR fuel pin cell and fuel assembly were analyzed using cosRMC .In addition ,the burnup of Gd rod was also analyzed in detail .The results show that the result using cosRMC agrees with that calculated by other well‐known codes .It is also shown that the difference of Pu content in fuel calculated by different codes increases with burnup .关键词
