摘要
在广义等效理论(GET)和超级均匀化方法(SPH)的基础上,提出同时满足反应率、界面流和组件特征值守恒,且不显式使用等效因子的超级等效方法(SPE)。在蒙特卡罗组件均匀化中应用SPE,将该方法植入蒙特卡罗组件均匀化程序MCMC,并通过C5G7基准题进行验证。验证分析表明:SPE等效均匀化群常数堆芯计算精度更高,适应性更广。
Based on the general equivalence theory （GET） and the superhomogenization method （SPH）, the super equivalence method （SPE） has been proposed to preserve the surface current, the reaction rates and the lattice reactivity, using the implicit equivalence factors. SPE has been implemented into the Monte Carlo method based homogenization code MCMC. The C5G7 benchmark problem has been calculated to verify the SPE method. The results show that the SPE method provides improved accuracy and adaptation compared to the traditional GET and SPH methods.
