SIMULATION SYSTEM FOR SEVERE ACCIDENT PHENOMENA OF THE NUCLEAR POWER PLANT

摘要

The present invention relates to an interactive simulation system for a severe accident in a nuclear power plant. The interactive simulation system for a severe accident in a nuclear power plant according to the present invention comprises: a user interface which receives a simulation command from a user; a severe accident interpretation engine which implements a dynamic linking library (DLL) using a severe accident interpretation code; and a controller which controls the severe accident interpretation engine by using the simulation command to simulate the severe accident in the nuclear power plant, and delivers the generated simulation result to the user interface to be outputted. The controller performs a plurality of control routes for controlling the severe accident interpretation engine and performs simulation including at least two steps. In particular, the controller is characterized to apply a simulation command, which is inputted while simulation is under progress, to a next step to be executed following a current step, such that the user can intervene and manipulate the simulation progress. Also, according to the present invention, simulation result data is stored in the order of time, and then sequentially loaded to be outputted when the user requests the result data. Therefore, user satisfaction can be improved by enabling the user to easily acknowledge and play back the simulation result.
