Abstract :
In this paper, the behavior of fission product is studied for 900 MW PWR. Especially, the radionuclide released from core under severe accident is simulated. The program is based on models in MELCOR, elements with similar chemical behavior in the reactor are treated as one class, 15 classes are used in the program. The core is divided into 33 cells altogether. For each cell and each class, radionuclide released from core at different time is calculated.
