Modular construction method for spent fuel heat shield of high-temperature gas cooled reactor
The invention provides a high-temperature gas cooled reactor spent fuel heat shield modular construction method which comprises the following steps: when a spent fuel vertical shaft is subjected to concrete construction, an embedded steel plate is arranged on the side wall of the spent fuel vertical shaft, a guide rail is mounted on the embedded steel plate, and the guide rail extends in the height direction of the spent fuel vertical shaft; a heat shield cylinder is divided into a plurality of sub-modules, the sub-modules are manufactured in a prefabricated mode, and supporting assemblies are arranged on the outer sides of the sub-modules; the position of the guide rail is measured, the supporting length of the supporting assembly is adjusted according to measurement data of the guide rail, all the sub-modules are sequentially hoisted into the spent fuel vertical shaft, and all the sub-modules are arranged in the height direction of the spent fuel vertical shaft; and when the sub-module is hoisted, one side, far away from the sub-module, of the supporting assembly is embedded in the guide rail. The spent fuel heat shield barrel has the technical effects that modular installation of the spent fuel heat shield barrel can be achieved, and the construction difficulty and the safety risk are effectively reduced.
本发明提供一种高温气冷堆乏燃料热屏模块化施工方法，包括如下步骤：乏燃料竖井在进行混凝土施工时，在乏燃料竖井的侧壁上设置预埋钢板，并在所述预埋钢板上安装导轨，且所述导轨沿乏燃料竖井的高度方向延伸；将热屏筒划分为多个子模块，采用预制的方式制作所述子模块，并在所述子模块的外侧设置支撑组件；对导轨的位置进行测量，根据导轨的测量数据调整所述支撑组件的支撑长度，依次吊装各个子模块至乏燃料竖井内，各个子模块沿乏燃料竖井的高度方向排布；在吊装所述子模块时，支撑组件的远离所述子模块的一侧嵌设于所述导轨内。本发明的一个技术效果在于，能够实现乏燃料热屏筒的模块化安装，有效地降低施工难度和安全风险。
