Abstract

Abstract

A two-step calculation scheme may be one of the feasible ways if we intend to do core simulations with Monte Carlo method,i.e.,assembly level calculations with Monte Carlo method（MCNP） are done at first,the group constants are tallied at the same time,and then the core level simulations are performed using these group constants.In this paper,the group constants generation method via Monte Carlo is studied,and an equivalent homogenization theory has been applied to improve the results.The numerical calculation results illustrate that the group constants generation method via Monte Carlo is practicable,which can improve the efficiency of core simulations while ensuring the accuracy.
- Monte Carlo,
- Group constants,
