A web-based nuclear simulator using RELAP5 and LabVIEW

A web-based nuclear reactor simulator has been developed using the best-estimate nuclear system analysis code RELAP5 as its engine, and abVIEW for graphical user interface and web-casting. Simulator retains the accuracy of the best-estimate code. Results are displayed in user riendly graphical format. Color-coded nominal values are displayed along with the current status of different variables in tab activated windows. ome variables of interest are also shown as a function of time. All graphical outputs are displayed in web browsers making the simulator’s front nd independent of the operating system. The interactive simulation feature allows the users to simulate specific reactor transients – such as LOCA, cram, etc. – using a single click. Simulator’s graphical output can be web-casted and is thus available to anybody with access to the web. Moreover, f permitted, the simulator can be operated remotely from another site connected to the server via the World Wide Web.
