This proposed PhD project will investigate the low source start-up and power ascension of nuclear power plants. The project is expected to have major benefits across the civil and defence nuclear businesses of Rolls-Royce. These benefits include a better understanding of low source start-up and power ascension as well as potential better placement of primary and secondary start-up sources or a reduction in the number of start-up sources within small modular nuclear reactor (SMR) power plants. It is important to note that primary start-up sources can cost as much as $60M per gram and reductions in dose to workers by deletion of start-up sources can be significant and support the "As Low As Reasonably Practicable (ALARP)" nuclear safety principles. Low source start-up and power ascension is an area of nuclear power plant (NPP) modelling that has received little or no research since the 1960's and is one area of nuclear engineering where a better understanding can improve the commissioning and start-up of NPPs. It is well known, as the NPP moves from the source range through to the power range, the behaviour of the NPP in the low source region is particular important from a nuclear safety perspective.

该拟议的博士学位项目将调查核电厂的低源启动和功率提升。预计该项目将在劳斯莱斯的民事和国防核业务中获得重大利益。这些好处包括更好地了解低源启动和功率提升，以及潜在的基本和次要启动源的位置，或减少小型模块化核反应堆（SMR）发电厂内的启动源数量。重要的是要注意，主要初创企业来源每克的成本高达6000万美元，并且通过删除启动来源的剂量减少对工人的剂量可能很大，并且支持“低于合理可行的（ALARP）”核安全原则。低源启动和电力提升是核电站（NPP）建模领域，自1960年代以来几乎没有研究，并且是核工程领域的一个领域，更好地了解可以改善NPP的调试和启动。众所周知，随着NPP从源范围转移到功率范围，从核安全性的角度来看，NPP在低源区域中的行为特别重要。
