HDF5数据格式在核反应堆计算软件中的应用研究

Application of HDF5 Data Format in Nuclear Reactor Computing Software

核反应堆计算软件需要处理和维护结构复杂且规模庞大的数据集合,为满足软件对海量数据进行存储和处理的需求,深入研究了分层数据存储格式HDF5 (Hierarchical Data Format v5)的数据存储模型、I/O方法和编程接口,并根据典型的核反应堆组件中子学计算、堆芯中子学计算和堆芯热工水力计算等软件数据存储和处理的需求,将HDF5数据格式成功应用到相应软件中,设计并实现了基于HDF5数据格式的组件参数库KYMRES (KYlin-2 Main RESults databank)、堆芯参数库COMRES (COrca-3D Main RESults databank)、子通道参数库THMRES (Thermal-Hydraulic subchannel Main RESults databank),为核反应堆数值计算软件开发提供了一种新的数据存储和管理方案。

Nuclear reactor computing software need to process and maintain complex and massive data sets.Inorder to meet the requirement of mass data storage and processing in software,the data storage model and I/Omethod and programming interface of HDF5(hierarchical data format v5)are deeply studied.According to thedata storage and processing requirement of typical nuclear reactor computing software such as assembly or coreneutronics computing software and core thermal-hydraulic computing software,K YMRES(kylin-2 main re-sults databank)and COMRES(corca-3d main results databank)and THMRES(thermal hydraulicsubchannel main results databank)are designed and implemented.A new data storage and management solutionfor nuclear reactor computing software is provided.
