摘要

乏核燃料（SNF）的干式储存和燃料组件的冷却对核工业至关重要。乏核燃料（SNF）将贮存在秦山核电站的混凝土干桶和室内干式贮存设施中。在本研究中，使用 Ansys Fluent 对所研究的干式贮存设施中以圆柱体形式存放 SNF 的八个垂直干式贮存桶的热情况对称边界和通风特性进行了模拟。模拟采用不可压缩理想气体，并使用低雷诺 k-ε 湍流模型。本研究对以下参数进行了分析：(i) 不同的热负荷；(ii) 不同的布置；(iii) 事故条件；(iv) 在设施中干式储藏系统（DSS）的出口位置安装主动通风系统。结果表明，干式储存系统的热负荷、半封闭和布置对设施内的温度分布有很大影响。在出口位置安装主动通风系统会影响工作人员，并显著降低设施内的温度分布。建议在今后的设计中将风扇转速设定为 600 至 750 rpm。这些结果为今后室内干燥储藏设施的设计提供了指导。

Thermal assessments for design and active ventilation system of indoor dry storage facility of Chinshan Nuclear Power Plant

Dry storage of spent nuclear fuel (SNF) and the cooling of fuel assemblies are essential for the nuclear industry. SNF will be stored in concrete dry casks and an indoor dry storage facility at the Chinshan Nuclear Power Plant. In this study, Ansys Fluent is used to simulate the symmetric boundaries of thermal cases and the ventilation characteristics of eight vertical dry storage casks for SNF as cylinders in the studied dry storage facility. Incompressible ideal gas is adopted in the simulation, and the low Reynolds k-ε turbulence model is used. The following parameters are analyzed in this study: (i) different heat loads, (ii) different arrangements, (iii) accident conditions, and (iv) installation of an active ventilation system at the outlet position of the dry storage systems (DSSs) in the facility. The results show that the DSS heat load, half-blockages, and arrangements significantly influence the temperature distribution in the facility. Installing an active ventilation system at the outlet position affects the staff and significantly decreases the temperature distribution in the facility. It is recommended that the rotational fan speed be set at 600 to 750 rpm for future designs. The results provide future design guidelines for indoor dry storage facilities.
