(NewTek: Pennsauken, NJ) -- NewTek Sensor Solutions, a U.S.-based manufacturer of linear and rotary position sensors, is developing an advanced linear variable differential transformer (LVDT) specifically designed to withstand the extreme environments found in next-generation molten salt reactors (MSRs). These reactors use molten salt as either a coolant or a solvent for nuclear fuel, providing a cleaner and safer approach to nuclear energy.

Accurate position measurement is essential in MSRs for monitoring and controlling essential mechanical systems, including control rods, fuel handling systems, and maintenance tools. However, designing sensors for these applications is challenging due to the high operating temperature, intense radiation, and corrosive nature of molten salts at elevated temperatures. Within the main containment areas, any sensors present must be rated in the 930°F to 1,300°F (500°C to 700°C) range.
