核电厂放射性源项程序DORAST可视化平台开发

Development of Visual Platform for Source Term Program DORAST

  • 摘要: 核电厂放射性源项计算程序DORAST能模拟核电厂一、二回路主要设备中气态及液态排放物的放射性活度,以及核电厂主要系统和设备中γ射线的能谱。DORAST程序可计算不同模式下的系统及设备达十余个,通过输入文件输入既耗时又难以保证文件的正确性,计算内容详实使得输出文件有信息量大、阅读困难的缺点。本文利用C#语言开发了友好的可视化界面,将输入参数、生成输入文件、调用可执行程序、对数据后处理生成相应的表格及图表等功能集于一身,极大地方便了用户的使用过程。可视化平台通过界面上的控件和后台程序中参数之间的数据交换来解决并优化问题,结合其输出文件,将其数据表格化,给出相应的图形显示,并能将计算得到的放射性活度直观地显示在核电厂模型图中,显著提升了DORAST程序的工程实用性。

     

    Abstract: DORAST, the radioactive source term calculation program for nuclear power plant, is to simulate radioactive activity and the γ energy spectrum of the radioactive liquid and gas in the main equipments of primary and secondary system. There are so more than ten calculation models integrated in the DORAST, that it’s time-consuming and difficulty to ensure the accuracy of the input file, in addition, the output file is so informative, that it contains much information as well as hard to read. On this issue, it was necessary to develop friendly visual interfaces with C# program, combining input of parameter, generation of input file, call of the executable program, and generation of the tables and figures in one, which was much convenient for users. With the data exchange of the controls on the interface and the parameter of back-ground process it solves optimization problems, as well, with the graphing and visualization of the data it gives an intuitive display in the model diagram, greatly improving the practicality of the use of the DORAST program.
