Abstract

The safety system for nuclear reactors continues to improve along with the development of the use of nuclear reactors as power generators. Likewise, early detection features in nuclear reactors are constantly evolving to produce the most optimum detectors. The increase in gamma radiation is one of the signs in the safety system of nuclear reactors so that the evolution of the detector refers to the gamma radiation detector. One consequence of the evolution of this detector is the production of detectors that have excellent capabilities but are very expensive. Plastic with the type of Poly Vinyl Toluene (PVT) can be used as a gamma detector and has a low cost. In this study, the possibility of using PVT-based scintillation detectors as an option for low-cost early detection features in nuclear reactor safety systems will be studied. The study was carried out by characterizing PVT-based scintillation detectors and then comparing them with commercial detectors. The parameter that is the main focus of this research is the efficiency of the detector.
