A radiotracer investigation was carried out in a Thermal Stratification Test Facility (TSTF) with objectivesof investigating the dispersion and diffusion of radionuclide and effectiveness of the thermocline tominimize the radionuclide content in the hot water layer. Technetium-99m (99mTc) as sodium pertechnetate was used as a radiotracer in the investigation. Qualitative analysis showed that a thermoclineis formed within the TSTF and is effective in preventing the transport of radionuclide from bottomsection to the top section of the facility. It was found that the radiotracer injected at the bottom of thepool took about 17.4 h to disperse from bottom to the top of the facility. The results of the investigationhelped in understanding the effectiveness of hot water layer and thus to minimize the pool top radiationlevels.
