| Abstract | ||
| The fission process of uranium-235 nucleus, produce radioactive fission gases such as (85Kr,135Xe) as the most important products. The risks of these products on the reactor safety and the environment are important the quantities of these radioactive gases depend on the fission rate inside the nuclear fuel; ie, on their yields in fission products. Uranium dioxide ceramics UO2 are widely used in pressurized water reactors (PWR). The calculations were obtained need by using (MATLAB R2011b), through calculating the effects of thermal power, neutrons flux, cooling water temperature. It was found that the quantities of radioactive gases produced increased with thermal power and neutrons flux. With the increase of coolant temperature led to decrease of the amounts of radioactive gases . | ||
