Description

The calculation results of dynamic of the fission product activity of the Chernobyl-4 reactor fuel in difference time before the accident in dependence from reactor mode are given. Influence of the accident neutron capacity overshoot on time change of total activity of fission products after accident was investigated. It is shown that in result of the accident capacity growth the specific activity of the fission products increased in 50 times in comparison with mode of minimal capacity level. The total activity of volatile isotopes increased in two times. Authors came to a conclusion that iodine 132 made important contribution in the radioactivity during first month after the accident
