Comparative Radiation Dose Study of a Hypothetical Accident in a Research Reactor

Abstract

This study is a contribution for radiation dose calculations of a hypothetical accident of a 1 MW research reactor Triga Mark II using HotSpot code. A postulated accidental release of noble gases and halogens were considered. The total effective dose (TED) was estimated for 1 day and 50 years after release. The total damage of fuel element cladding with a maximum radioactivity was considered. The obtained results show minimal TED values at the beginning of the release and at a shorter distance from the source. The maximum calculation results are acceptable and below the recommended public dose limit.

“…Additionally, to provide the most accurate description of the doses, the Health Physics Code Hot Spot [37] of Lawrence Livermore National Laboratory (LLNL laboratory was used to display the boundary contour line areas of the doses at the release location in Google Earth, using geographical coordinates of the 3 MW Triga Mark II reactor. There are three marked contours with different colours; the red contour represents the highest dose risk for the population in the inner area, while the green and blue contours represent the middle and outer doses [38]. The area is divided into three distinct regions, each marked with a different colour contour.…”
