Resumé

Most of the literature exists on the simulation of accidental release from chemical or nuclear plant. In this work we have carried out fundamental modelling of radioactive release under normal operating conditions. An attempt is made to estimate the airborne radionuclide concentration in the atmosphere from probable release from stack. The effect of release stack height and the radionuclide source strength on the airborne radionuclide concentration are studied. The location of maxima of airborne radionuclide concentration is investigated in this work. The released source strength was varied to study the impact on the radionuclide concentration profile. Study reveals with increase in source strength of radionuclide airborne concentration of radionuclide increases.  It is observed from the study that for similar weather condition even though source strength was varied the concentration profiles remain same and only absolute value of maxima increases with source strength. The maximum airborne concentration of radionuclide was estimated 1.03E-01 Bq/m3 for 50 m high stack release considering radioactive release source strength of 1.807E-03 Bq/s.
