Radiation induced heating modelling within nuclear reactor physics simulations

这个博士项目的目的是改进核反应堆堆芯和屏蔽内中子和伽马射线光子辐射诱导加热率的建模和模拟（M&S）。中子和伽马射线光子辐射诱导的加热速率的这种改进的M&S可以通过改进的核数据的发展来实现（即，微观中子截面，γ射线光子相互作用系数和KERMA因子），不确定性量化（即，中子和伽马射线光子截面协方差数据），以及使用现代的、并行的、确定性的、耦合的中子和伽马射线光子输运软件，如罗尔斯·罗伊斯AVARIS辐射输运M&S框架。

The aim of this PhD project is to the improve the modelling and simulation (M&S) of neutron and gamma-ray photon radiation induced heating rates within nuclear reactor cores and shields. This improved M&S of neutron and gamma-ray photon radiation induced heating rates with be achieved through the development of improved nuclear data (i.e., microscopic neutron cross-section, gamma-ray photon interaction coefficients and KERMA factors), uncertainty quantification (i.e., neutron and gamma-ray photon cross-section covariance data) as well as the use of modern, parallel, deterministic, coupled neutron and gamma-ray photon transport software such as the Rolls-Royce AVARIS radiation transport M&S framework.
