摘要

本文提出了钍铀燃料模块化高温气冷堆芯简化建模的体积均化方法。该方法显著降低了三维数值模型的复杂性。因此，与耗时的中子输运蒙特卡罗建模相关的计算时间大大减少。示例结果包括初始堆芯的几种配置的有效中子增殖因子和可裂变同位素（233U、235U、239Pu、241Pu）的时间演变。

Numerical modelling of modular high-temperature gas-cooled reactors with thorium fuel

Abstract The volumetric homogenization method for the simplified modelling of modular high-temperature gas-cooled reactor core with thorium-uranium fuel is presented in the paper. The method significantly reduces the complexity of the 3D numerical model. Hence, the computation time associated with the time-consuming Monte Carlo modelling of neutron transport is considerably reduced. Example results comprise the time evolutions of the effective neutron multiplication factor and fissionable isotopes (233U, 235U, 239Pu, 241Pu) for a few configurations of the initial reactor core.
