طراحی مفهومی سیستم اندازه‌گیری غنا و وزن پودر اورانیم‌ تترافلوراید

One of the key steps in the nuclear fuel cycle is uranium enrichment. It is essential to control processes using continuous measurement on the way to uranium with the desired enrichment of the facility. On the other hand, due to being in an environment with high external radiation and also suitable for internal exposure of the operator, especially when working with uranium powder, it is necessary to use accurate instruments with the ability to monitor online and continuously, which is a special place in nuclear instrumentation. In this work, we worked on a conceptual design of the enrichment and weight measurement system for uranium tetrafluoride powder in loading and handling tanks. This is in the nuclear industry. To reduce costs while eliminating maximum counting errors, only gamma rays emitted from powder or with radioactive lateral sources were considered. The design was based on geometric location optimization of scintillating detector/detectors around the tank containing uranium tetrafluoride powder to have maximum measurement accuracy. The simulation results in Monte Carlo software show that for different enrichment percentages and different heights of uranium powder inside the cylindrical tank, we can have the greatest accuracy in measuring two parameters, enrichment percentage and powder weight at specific angles.
