Development And Application Of Nuclear Reactor Physics Simulation Code Graphic User Interface

REMARK program is a thorough and proven nuclear reactor physics simulation software,which could achieve refined calculation by making reactor discrete in space.But it is hard to learn and use because the input card of REMARK has complex construction and plenty of parameters.Even though researchers have got used to REMARK,it is possible to lead to man-made input mistake because of the strong correlation of input parameters.Therefore,it is necessary to establish a graphic user interface,which could reduce the workload of modeling and filling in input cards apparently.Meanwhile it could lower the possibility of modeling by mistake obviously and cut the time of inspection down,make the course of modeling more rapid and convenient.Hence,the paper researches the content and construction of REMARK input cards,classify all parameters in cards by writing law.The paper draws up corresponding projects for cutting down the workload,and succeeds to set up an interface which packages all parameters and realizes simplified process of writing input cards by computer programs.In addition,researchers usually need simulate a nuclear reactor for its coupled neutronics and thermal-hydraulics characteristics,especially the power distribution.However,current coupled neutronics and thermal-hydraulics programs are specific.Therefore,the paper establishes a new interface,used to work out coupled calculating project and generate calculating program files,based on REMARK program and RELAP5 program.The new interface could be regarded as an important part of graphic REMARK modeling interface.It permits researchers to build various models and writes corresponding program files automatically.Finally,a typical PWR is choosen to prove that it could be simulated as an example by the interface and program files which is builded by the paper.The steady state operation characteristics of the example is observed,the function of the interface is tested,and finally a conclusion is got that the interface can satisfy simulation need and be easy to come into use.
