Abstract: 

Radioactive protection is one of the most important subjects in nuclear power plants safety. Analysis of BNPP spent fuel pool shielding, as a main source of energetic g-rays was the main goal of this project. Firstly, we simulated the reactor core using WIMSD-4 neutronic code and the amount of fission product in the fuel assembly (FA) was calculated during the reactor operation. Then, by obtaining the results from the previous calculation and by using MCNP4C nuclear code, the intensity of g-rays was obtained in layers of spent fuel pool shields. The results have shown that no significant g-rays passed through these shields. Finally, an accident and resulting exposure dose above the pool was analyzed.
