Abstract
The purpose of this work is to estimate dose received in case of release of radionuclide into the atmosphere from the under-construction Rooppur Nuclear power plant (NPP) due to a hypothetical accident with the help of an atmospheric dispersion model. A generic source term code has also been developed using MATLAB by following NUREG-1228. The sensitivity analysis is based on variation of the received total effective dose equivalent (TEDE) corresponding to the variation of the uncertain input parameters. The sensitivity was seen to be higher at stable conditions with the change of high wind speed. Estimated TEDE dose results for Xe-133 at different downwind distances from Rooppur NPP site in different atmospheric stability classes. The maximum TEDE of 6.40E-06 Sv was estimated at maximum distance of 0.7 km from the site for stability class A, whereas, in case of unstable stability class B, it was 5.70E-05.
期刊介绍：
The IJLR is a peer-reviewed journal dedicated to the publication of research articles, review papers and technical notes in all domains related to low-dose radiation, among which are the biological and health effects in humans and the biota, in vitro and in vivo research on low radiation effects, regulatory and policy aspects, risk estimation and public perception.
