Computational Modelling and Simulation of Low Source Start-up and Power Ascension in Advanced Nuclear Power Plants (NPP)

本博士项目将研究核电厂的低源启动和功率提升。该项目预计将对劳斯莱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提升，以及可能更好地放置初级和次级启动源或减少小型模块化核反应堆（SMR）发电厂内启动源的数量。值得注意的是，主要启动源每克的成本可能高达6000万美元，通过删除启动源可以显著减少对工人的剂量，并支持“尽可能低的合理可行（ALARP）”核安全原则。低源启动和功率提升是核电厂（NPP）建模的一个领域，自20世纪60年代以来很少或没有研究，这是核工程的一个领域，更好的理解可以改善NPP的调试和启动。众所周知，随着核电站从源范围进入功率范围，从核安全的角度来看，核电站在低源区域的行为尤为重要。

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.
