Abstract
The revision of safety analysis report of TR-2 research reactor had been initiated in 1995. The
whole accident analysis and accepted scenario for maximum credible accident has been revised
according to the new safety concepts and the impact to be given to the environment due to this
scenario has been assessed. This paper comprises all results of these calculations.
The accepted maximum credible accident scenario is the partial blokage of the whole reactor
core which resulted in the release of 25% of the core inventory. The DOSER code which uses
very conservative modelling of atmospheric distributions were modified for the assessment
calculations. Pasquill conditions based on the local weather observations, topography, and
building affects were considered. The thyroid and whole body doses for 16 sectors and up to 10
km of distance around ÇNAEM were obtained. Release models were puff and a prolonged one
of two hours of duration. Release fractions for the active isotopes were chosen from literature
which were realistic.
