摘要
为解决多维计算程序对铅铋堆主回路进行长时间模拟时所需计算资源庞大的问题,基于自主开发的一维CFD程序,将零维点堆动力学模型及二维燃料棒传热模型集成到其中,并进行多物理场耦合,开发了一款适用于池式铅铋堆的系统分析程序。使用OECD/NEA发布的加速器驱动次临界系统(ADS)失束事故国际基准例题,对所开发程序进行稳态以及瞬态验证,以确保模型准确性。验证结果表明,所开发程序在关键参数上与发布结果吻合较好,且所需计算资源明显小于多维程序,证明了该程序可以对池式铅铋堆进行初步的热工水力及安全分析。
To solve the problem that multidimensional computing code needs huge computing resources when itsimulates the lead-bismuth reactor for a long time,based on the self-developed one-dimensional CFD code,integratingthe zero-dimensional point reactor dynamics model and the two-dimensional fuel rod heat transfer model,and carringout the multi-physical field coupling,we have developed a system safety analysis code for lead-bismuth pool reactor.The international benchmark for Accelerator Driven Sub-critical System(ADS)beams transient accident,which waspublished by OECD/NEA,was used to process the steady-state and transient validation,and to ensure the accuracy ofthe model.The verification results show that the code developed is in good agreement with the published results interms of key parameters,and the computational resources required are obviously smaller than those of the multi-dimensional computing code.It is proved that this code can be used for preliminary thermo-hydraulic and safetyanalysis of lead-bismuth reactor.
