An assessment for determining N-16 activity concentrations during the operation condition ofBangladesh Atomic Energy Commission TRIGA Research Reactor was performed employing severalgoverning equations. The radionuclide N-16 is a high energy (6.13 MeV) gamma emitter which is predominatelycreated by the fast neutron interaction with O-16 present in the reactor core water. Duringreactor operation at different power level, the concentration of N-16 at the reactor bay region may increasecausing radiation risk to the reactor operating personnel or the general public. Concerning thesafety of the research reactor, the present study deals with the estimation of N-16 activity concentrationsin the regions of reactor core, reactor tank, and reactor bay at different reactor power levels under naturalconvection cooling mode. The estimated N-16 activity concentration values with 500 kW reactor powerat the reactor core region was 7:40 105 Bq=cm3 and at the bay region was 3:39 10 5 Bq=cm3. At3 MW reactor power with active forced convection cooling mode, the N-16 activity concentration in thedecay tank exit water was also determined, and the value was 4:14 10 1 Bq=cm3.
