Abstract

The safety measures for nuclear reactors are constantly advancing in line with the progress in utilizing nuclear reactors as power sources. Furthermore, the capabilities of early detection systems in nuclear reactors are always advancing to provide the most efficient detectors. Gamma radiation rise serves as an indicator in the safety system of nuclear reactors, specifically in relation to the gamma radiation detector. An outcome of the advancement of this detector is the creation of detectors that possess exceptional capabilities but come with an expensive cost. Poly Vinyl Toluene (PVT) plastic can function as a gamma detector and is cost-effective. This study aims to investigate the possibility of utilizing PVT-based scintillation detectors as a cost-effective solution for incorporating early detection capabilities into nuclear reactor safety systems. The work involved the characterization of PVT-based scintillation detectors, followed by a comparison with commercially available detectors. The primary focus of this research is the efficiency of the detector parameter.
