一种辐照屏蔽保温结构
摘要：
本发明属于反应堆结构设计技术领域，具体涉及一种辐照屏蔽保温结构。本发明安装在由换料水池、环梁、反应堆压力容器围成的封闭空腔内，其包括辐照屏蔽材料、高效隔热保温层和包壳，高效隔热保温层覆盖在辐照屏蔽材料临近反应堆压力容器的一侧，包壳整体封装辐照屏蔽材料和高效隔热保温层。本发明能够有效降低辐照屏蔽材料温度和反应堆压力容器热损失，避免辐照屏蔽材料高温失效；能够阻碍辐照通过，降低反应堆厂房操作平台辐照剂量，降低结构设备活化水平。
摘要（英）：

The invention belongs to the technical field of reactor structure design, and particularly relates to an irradiation shielding thermal insulation structure. The structure is installed in a closed cavity defined by a refueling pool, a ring beam and a reactor pressure vessel and comprises an irradiation shielding material, an efficient thermal insulation layer and cladding. The efficient thermal insulation layer covers the side, close to the reactor pressure vessel, of the irradiation shielding material, and the irradiation shielding material and the efficient thermal insulation layer are integrally packaged in the cladding. The temperature of the irradiation shielding material and the heat loss of the reactor pressure vessel can be effectively reduced, and high-temperature failure of the irradiation shielding material is avoided; irradiation passing can be hindered, the irradiation dose of a reactor plant operation platform is reduced, and the activation level of structural equipment isreduced.
