摘要： PURPOSE: An internal structure disposed within a nuclear reactor vessel, the structure including an internal structural member configured and disposed, is provided to be capable of stabilizing the coolant flow in a region located near or close to an outlet nozzle, to thereby eliminate or mitigate difficulties which may otherwise be involved in the temperature measurement of the coolant flowing through the outlet pipe. CONSTITUTION: A short member(1) serving as a flow stabilizing member is mounted within the upper plenum(40) in an outer region extending outside of the fuel region along the inner wall of the core barrel(30) at a position lower than the outlet nozzle(12). In this conjunction, the phrase "outer region extending outside of the fuel region" means a region on the upper surface of the upper core plate(21) extending outside of the fuel assembly region(33) within the upper plenum(40) the outer periphery thereof corresponding to that of the core. Further, the phrase "at a position lower than the outlet nozzle(12)" means that the top end of the flow stabilizing member(1) in the mounted state within upper plenum(40) is lower than a lowermost portion of the bore of the outlet nozzle(12).
摘要翻译：目的：设置在核反应堆容器内的内部结构，包括构造和设置的内部结构构件的结构能够使位于靠近或靠近出口喷嘴的区域中的冷却剂流稳定，从而消除或减轻否则可能涉及流过出口管的冷却剂的温度测量的困难。构成：用作流动稳定构件的短构件（1）在位于中心筒（30）的内壁的外侧区域的外部区域内安装在上部空间（40）内，该外部区域在低于出口喷嘴（12）。在这一点上，短语“延伸到燃料区域外部的外部区域”是指在上部集气室（40）内延伸到燃料组件区域（33）外侧的上部芯板（21）的上表面上的区域，外部其周边与芯的边缘相对应。此外，短语“在比出口喷嘴（12）低的位置”是指在上部空间（40）内处于安装状态的流动稳定构件（1）的顶端低于孔的最下部出口喷嘴（12）。
