Designing an efficient reactor core simulation strategy for the Canadian-SCWR

加拿大scwr是第四代能源系统，其设计基于以下两个考虑：卓越的安全性和可靠性，以及极低的反应堆堆芯损坏可能性和程度。由于SCWR是一个核系统，它的一般行为是由反应堆物理控制的，它被用来预测堆芯中中子的数量随时间的变化，以及堆芯性质变化引起的反应性变化。本文提出了一种基于反应堆物理数值模拟的加拿大scwr高效模拟策略。这意味着选择能够模拟堆芯结构的反应堆物理软件，在软件和仿真策略中实现新的模型，以提高分析的精度，并优化正常运行条件或事故情景下的反应性控制机制和停机系统。

The Canadian-SCWR is a Generation IV energy system that is designed based on the following two considerations: excellence in safety and reliability and a very low likelihood and degree of reactor core damage. Because the SCWR is a nuclear system, its general behavior is controlled by reactor physics, which is used to predict the population of neutrons in the core with time as well as the changes in reactivity resulting from variation in the core properties. Here we propose to design an efficient simulation strategy for the Canadian-SCWR based on numerical simulation in reactor physics. This implies selecting reactor physics software that can model the core configuration, implementing new models in the software and in the simulation strategy to improve the precision of the analysis and optimize the reactivity control mechanism and shutdown systems for normal operation conditions or during accident scenarios.
