摘要: 聚变装置主机大厅屏蔽门作为屏蔽措施的重要组成部分,需具备优异的中子与光子屏蔽性能,并确保其结构强度、地震稳定性及气密性,以保障外围环境和人员的安全。基于内层50 mm碳钢、中间层500 mm掺硼聚乙烯、最外层250 mm碳钢的复合屏蔽结构,采用蒙特卡罗粒子输运程序cosRMC开展了屏蔽门屏蔽性能的模拟分析,结果显示屏蔽门屏蔽性能均优于1 000 mm厚混凝土墙体,满足屏蔽性能要求。针对大型屏蔽门自重大、开闭较为频繁的功能特点,设计了铰链、驱动和锁紧机构。基于有限元ANSYS软件分析,屏蔽门主体部件在正常工况和地震工况下的最大等效应力分别为25.9 MPa和30.2 MPa,最大剪切应力分别为13.8 MPa和16.1 MPa,最大变形分别为0.048 mm和0.052 mm,均满足设计要求。

Abstract: The radiation shielding door located in the main hall of the fusion device is a crucial component of the shielding arrangementss, requiring excellent neutron and photon shielding performance, while maintaining structural strength, seismic stability and airtightness to safeguard both the surrounding environment and personnel safety. Based on a composite shielding structure consisting of a 50 mm carbon steel inner layer, a 500 mm boron-doped polyethylene middle layer, and a 250 mm carbon steel outer layer, a Monte Carlo particle transport program (cosRMC) was used to simulate the shielding performance of the door. The results show that the shielding performance of the radiation shielding door exceeds that of a 1 000 mm thick concrete wall, satisfying the required shielding performance criteria. Considering the functional characteristics of the large radiation shielding door, which has a significant weight and undergoes frequent opening and closing, hinge, drive and locking mechanisms were designed. Finite element analysis performed using ANSYS software indicates that, under normal operating conditions, the main structural components exhibit maximum equivalent stresses of 25.9 MPa, maximum shear stresses of 13.8 MPa, and maximum deformations of 0.048 mm; under seismic design basis conditions, the corresponding values are 30.2 MPa, 16.1 MPa, and 0.052 mm, respectively.All values meet thd design requirements.
