Reducing Measurement Time in Nuclear Calorimetry
Reduce nuclear material characterization time with power-compensation calorimetry, designed for efficiency, accuracy, and operational constraints.
Challenges related to time constraints for characterization in nuclear facilities
In nuclear facilities, calorimetric characterization of nuclear materials is essential for inventory control, safeguards, and safety. Depending on container size, activity, and thermal properties, measurement times can range from a few hours to several days. Multiplying measurement stations is often not economically or operationally viable, making time optimization a critical challenge.
The solution offered by power-compensation calorimetry
Conventional calorimeters operate in passive mode, measuring the natural heat flow generated by the container until thermal equilibrium is reached. Power-compensation calorimetry accelerates this process by maintaining a controlled thermal power inside the calorimeter using an electrical heating system. The required compensation power is directly linked to the container’s thermal output, enabling faster stabilization without compromising accuracy.
Heat-Check FAST: faster measurements, same reliability
Setsafe’s Heat-Check FAST calorimeters use power-compensation technology to significantly reduce measurement time.
For example, a 15-liter container can typically be characterized in 2 to 3 hours, compared to 3 to 4 hours with a standard passive calorimeter, representing a 20–30% time reduction.
This makes Heat-Check FAST particularly suited for high-throughput nuclear operations.
