翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Core shroud ： ウィキペディア英語版 Core shroud A core shroud is a stainless steel cylinder surrounding a nuclear reactor core whose main function is to direct the cooling water flow. The nuclear reactor core is where the nuclear reactions take place. Because the reactions are exothermic, cool water is needed to prevent the reactor core from melting down. The core shroud helps by directing this cool water towards the reactor core, providing stability to the nuclear reactions. == Structure == The core shroud is composed of multiple cylindrical thermal shields stacked on top of each other. In between each thermal shield is a horizontal, stainless steel cylindrical plate that helps keep the thermal shields in place. The plates are then welded together with the thermal shields so that they create one solid structure.Vertical tie bolts are then used to reinforce each horizontal plate with their adjacent thermal shields, stabilizing the cylindrical core shroud. The thermal shields are needed because the core shroud exists near the nuclear reactor core where heat is constantly present. The thermal shields prevent heat from damaging the core shroud by absorbing or reflecting the heat. Core shroud walls are relatively thin, ranging from three to five centimeters in thickness.〔 This is because the core shroud is not built to withstand high amounts of pressure for long periods of time, so thicker walls would be unnecessary for the core shroud's function. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Core shroud」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
