项目摘要

Current reactor safety codes are designed to assess the fuel thermal behaviour under normal and accident conditions of CANDU reactors. These safety codes may have been modified to predict fuel thermal behaviour at conditions relevant to supercritical water-cooled reactors (SCWR) but for an idealized geometry. The results of the present Phase II research proposal will provide an improved heat transfer prediction method to be used in reactor safety codes in order to make them more applicable to various normal and accident SCWR conditions and applicable for a more realistic flow geometry, i.e. by considering (i) the flow direction effect, (ii) the effect of flow geometry (by comparing the supercritical heat transfer (SCHT) in tubular geometries vs. bundle geometries), (iii) the presence of flow obstructions, e.g., introduced by fuel rod spacers, and (iv) transient flow conditions, with time dependent pressure, mass flow and/or heat flux. This will enable the reactor safety analysts to better assess the impact of the previously mentioned separate effects on the sheath temperature behaviour during normal operating and accident conditions.
现行的反应堆安全规范旨在评估CANDU反应堆在正常和事故条件下的燃料热行为。 这些安全代码可能已经被修改,以预测燃料的热行为在相关的条件下,超临界水冷反应堆(SCWR),但一个理想化的几何形状。本第二阶段研究提案的结果将提供一种改进的传热预测方法,用于反应堆安全规范,以使其更适用于各种正常和事故SCWR条件,并适用于更现实的流动几何形状,即通过考虑(i)流向效应,(ii)流动几何形状的影响(通过比较管状几何形状与管束几何形状中的超临界传热(SCHT)),(iii)流动障碍物的存在,例如,由燃料棒间隔件引入,以及(iv)瞬态流动条件,具有时间依赖的压力、质量流量和/或热通量。 这将使反应堆安全分析人员能够更好地评估在正常运行和事故条件下,上述单独效应对鞘层温度行为的影响。
