参考俄罗斯的“罗蒙诺索夫” 号浮式核电站的总布置示意图以及相关文献资料，本文设计一个浮式核电站的堆舱安全壳舱段并建立有限元模型。在堆舱安全壳舱段的温度场计算中，本文将舱段依照结构划分为75个封闭腔室，并假设任一腔室内空气温度保持恒定。根据封闭无源空腔的热流量守恒，计算出舱段内各个腔室的空气温度。将腔室空气温度带入有限元分析软件Abaqus进行舱段温度场计算，得到舱段的温度分布。采用顺序耦合法计算舱段的温度应力，在设置舱段的力学边界条件后，将温度场作为预设场施加在舱段力学有限元模型上，有限元分析软件Abaqus进行计算，得到舱段的温度应力分布。
Referring to layout of barge design for floating nuclear power plant of "Academician Lomonosov" and related literature, this paper has design a nuclear compartment tank and established the finite element model. For the calculation of thermal field of the nuclear compartment tank, it was divided into 75 closed cavities. Based on thermal equilibrium, the inflow and outflow of heat are equal for any closed passive cavity. So each air temperature of cavity was calculated, and the thermal field of nuclear compartment tank was obtained using the ABAQUS software. Sequentially coupled method was carried out for the calculation of thermal stress, thermal field was applied on the finite element model as the pre-defined field under mechanical boundary conditions. Using the ABAQUS software, thermal stress distribution of the nuclear compartment tank was obtained.
