High performance deterministic radiation transport methods for SMRs

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。这一输运方程在许多学术和工业重要的工程和物理领域是核心的，包括：核反应堆物理、反应堆屏蔽、核临界安全评估、医学成像、核安全、云和太阳辐射传输物理、等离子体中的光子传输和纳米级电子器件。

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. This transport equation is central to a wide variety of academically and industrially important areas of engineering and physics including: nuclear reactor physics, reactor shielding, nuclear criticality safety assessment, medical imaging, nuclear security, cloud and solar radiative transfer physics, photon transport in plasmas and nano-scale electronic devices.
