摘要

大型熔盐储罐作为钍基熔盐堆（thorium molten salt reactor，TMSR）储能与能量释放的核心设备，其抗震性能直接影响整个系统的稳定性和经济性。为明确大型高温熔盐储罐在地震荷载下的动力响应特性及简化计算方法的适用性，以TMSR系统隔离回路立式薄壁熔盐储罐为对象，分别采用弹簧-质量方法、附加质量方法和声固耦合法建立三维有限元数值模型，开展模态和地震反应谱计算，对三种抗震分析方法得到的熔盐晃动频率、储罐振动频率及抗震评定结果进行了比较。结果表明：弹簧-质量法与声固耦合法均可准确求解熔盐晃动频率，所得地震应力结果基本相当；声固耦合法计算的储罐水平自振频率与API 650规范吻合较好，弹簧-质量法计算结果偏大，附加质量法计算结果偏小。地震作用下，三种方法的应力评定结果均满足规范要求且具有约50%的安全裕量，其中声固耦合法最贴合实际，但计算耗时最长，附加质量法较其计算效率提升10.5倍，且建模简单、收敛稳定。此外，熔盐储罐竖向振动有效参与质量占比极低，对整体抗震响应影响极小，工程分析中可忽略竖向地震作用。综合建模难度、计算成本与工程效率，本研究建议采用附加质量法进行抗震计算，可为同类型高温熔盐储罐的抗震分析方法的选取提供工程指导依据。

Abstract

As the core equipment for energy storage and release within a thorium molten salt reactor (TMSR)

large-scale molten salt tanks directly determine the stability and economic efficiency of the entire system. To clarify the dynamic response characteristics of large-scale

high-temperature molten salt tanks under seismic loads and the applicability of simplified calculation methods

a vertical thin-walled molten salt tank in the TMSR isolation loop was selected as the research object. Three-dimensional finite element models were developed using the spring-mass

added-mass

and acoustic-structure coupling methods to perform modal analysis and seismic response spectrum calculations. Subsequently

the molten salt sloshing frequency

tank vibration frequency

and seismic evaluation results obtained using the three seismic analysis methods were compared. The results demonstrate that both the spring-mass and acoustic-structure coupling methods can accurately calculate the molten salt sloshing frequency with equivalent seismic stress results. The horizontal natural vibration frequency calculated using the acoustic-structure coupling method agrees well with the API 650 code

whereas the values calculated using the spring-mass and added-mass methods are overestimated and underestimated

respectively. Under seismic action

the stress evaluation results from all three methods meet the code requirements with a safety margin of approximately 50%. Although the acoustic-structure coupling method is the most realistic

it requires the longest computation time. The added-mass method is 10.5 times more efficient and provides simpler modeling and more stable convergence. In addition

the vertical vibration effective mass participation ratio of molten salt tanks is extremely low

negligibly affecting the overall seismic response. Therefore

the vertical seismic action can be ignored in engineering analysis. Considering modeling difficulty

computational cost

and engineering efficiency

the added-mass method is recommended for seismic analysis. The findings of this study can serve as a reference for selecting seismic analysis methods for similar high-temperature molten salt tanks.
