Containment System for Heating and Off-Gassing
TS-065424 — Due to environmental concerns and the decreasing supply of fossil fuels, there is substantial demand for nuclear-based energy production. Nuclear energy now provides about 10% of the world's electricity from about 440 power reactors and is the second largest source of low-carbon power. In addition, over 50 smaller countries utilize nuclear energy in about 220 research-size reactors. These reactors are used to produce medical and industrial isotopes and several other purposes.
It is essential to meet the safeguard requirements in liquid-fueled molten salt reactors, fuel salt transportation, and fuel cycle processes and to develop effective methods for measuring and monitoring the mass of molten fuel salt or coolant salt. However, due to the complex and dynamic nature o…
