The aim of this PhD project is to develop novel numerical algorithms on modern, multi-core and many-core, high performance distributed computing (HPC) architectures for radiation shielding analyses of small modular reactors (SMRs) such as the steam raising nuclear power plants (NPPs) of nuclear submarines or the new Rolls-Royce, civil nuclear, SMR concept. The computational analysis of radiation shielding and dosimetry problems, in general, requires the solution of a complex transport equation that describes the migration of neutral particles through a prescribed host medium such as a radiation shield. Its application to the modelling and simulation of nuclear power plants (NPPs) is challenging because of the complex three-dimensional geometries involved as well as the presence of void or ducts within the geometry; especially in reactor shielding analyses.

该博士项目的目的是在现代、多核和高性能分布式计算(HPC)体系结构上开发新的数值算法，用于小型模块反应堆(SMR)的辐射屏蔽分析，例如核潜艇的蒸汽提升核电站(NPP)或新的劳斯莱斯、民用核、SMR概念。辐射屏蔽和剂量学问题的计算分析通常需要求解描述中性粒子通过规定的主体介质(如辐射屏蔽)的迁移的复杂输运方程。它在核电站(NPP)的建模和仿真中的应用具有挑战性，因为所涉及的复杂的三维几何以及几何中存在的空洞或管道；特别是在反应堆屏蔽分析中。
