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.
