Abstract
A study of radiation dose for the accident condition in the Subcritical Assembly for 99Mo Production (SAMOP) reactor experimental facility has been done. The main purpose of this study is to estimate the radiation dose received by worker as well as society during accident condition in the SAMOP reactor experimental facility. In this study, one of the worst accident scenario that has the highest probability is postulated as one of TRIGA fuel fall down in to the SAMOP reactor core during loading-unloading process. That accident inflicts one of this TRIGA fuel broken and radioactive materials are released. The radiation dose is estimated based on the radioactive source-term from ORIGEN 2.1 computer code calculation. Furthermore, the total effective dose equivalent (TEDE) received by the society is calculated using dispersion model of Hotspot 3.0 computer code. From this study, the total radiation dose received by the radiation worker during this accident condition is 4.5 mSv and the maximum TEDE received by society during this accident condition is 0.031 mSv. This study shows that the radiation dose received by worker as well as society during this accident condition is still below the limit appointed by regulatory body (BAPETEN).
