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.

本博士研究计画将探讨核能发电厂之低源启动与功率Ascension。该项目预计将对罗尔斯·罗伊斯的民用和国防核业务产生重大影响。这些好处包括更好地理解低源启动和功率Ascension，以及可能更好地放置一次和二次启动源或减少小型模块化核反应堆（SMR）电厂内的启动源数量。重要的是要注意，主要启动源的成本可能高达每克6000万美元，通过删除启动源可以显著减少工人的剂量，并支持“合理可行的最低水平（ALARP）”核安全原则。低源启动和功率Ascension是核电厂（NPP）建模的一个领域，自20世纪60年代以来，很少或根本没有研究，也是核工程的一个领域，更好地理解可以改善NPP的调试和启动。众所周知，随着NPP从源范围移动到功率范围，从核安全的角度来看，NPP在低源区的行为特别重要。
