摘要

本文讨论了为确定AP600压水堆(PWR)上部水头区域的热混合程度而进行的研究。这一信息最终有助于评估上顶头本身及其邻近部件的热致应力。顶部区域的冷却剂温度曲线在浮力显著的瞬态评估中也很重要,例如自然循环(NC)冷却。

Computational Fluid Dynamics Analysis of Thermal Mixing in the AP600 Upper Head
The paper discusses studies conducted to determine the extent of thermal mixing in the upper head region of the AP600 pressurized water reactor (PWR). This information is ultimately useful in the assessment of thermally-induced stresses in the upper head itself and the components adjacent to it. Coolant temperature profiles in the upper head region are also of interest in the evaluation of transients in which buoyancy forces are significant, such as natural circulation (NC) cooldown.
