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.
