The Ring RPT Method for DH Systems Containing Dispersed Particle-Type of Fuel and Burnable Poisons

Autor: Lei Lou, Xingjie Peng, Xiaoming Chai, Dong Yao, Mancang Li, Lianjie Wang, Liang Chen

Publikováno v: Frontiers in Energy Research, Vol 9 (2021)

Because dispersed particle-type fuel and burnable poisons both have double heterogeneity (DH), using the traditional volumetric homogenization method (VHM) to treat DH systems will bring about large reactivity calculation deviation. The improved reac
