About the Heat Check SV
Solving Nuclear Waste Measurement Challenges
Nuclear facilities face stringent requirements when it comes to the classification and disposal of radioactive waste. For waste packages containing alpha and beta emitters, quantifying heat output accurately is essential to ensure safe storage, compliance with regulatory thresholds, and long-term repository planning. The Heat Check SV calorimeter addresses this challenge by providing a non-destructive, automated solution for precise heat release measurement in small volume containers.
Technical Overview: Advanced Calorimetry and Thermal Sensing
The Heat Check SV employs a high-sensitivity calorimetric chamber with advanced thermal insulation and temperature control systems. Waste containers are placed into the sealed chamber where even minor temperature increases are captured and translated into heat output values. This makes it possible to determine the decay heat from isotopes like plutonium-238, strontium-90, and tritium.
A key advantage of this system lies in its automation. With pre-programmed cycles and minimal manual handling, the calorimeter eliminates operator variability, ensuring consistent and reproducible results. It’s especially suited for facilities where waste stream characterisation is frequent and high accuracy is mandatory.
Use Cases: Broad Applicability Across Nuclear Sectors
Nuclear Facility Operations
Nuclear engineers and operations managers use the Heat Check SV to validate that heat release from stored waste does not exceed licensing thresholds. It provides the data needed to safely store, classify, and plan disposal of containerised waste.
Radioactive Waste Management Agencies
Governmental and private-sector waste handling authorities deploy the Heat Check SV as part of their characterisation toolkit, especially for legacy or decommissioned waste streams. Its non-destructive nature makes it ideal where repackaging is not feasible.
Environmental Remediation Projects
Post-clean-up waste and decommissioned site materials are frequently analysed in small containers. The SV enables verification of remaining isotope activity, supporting clearance and disposal planning.
Regulatory and Compliance Use
With its robust data outputs and traceable operation, the system is ideal for nuclear regulators and inspectors seeking to validate declared heat output figures or audit waste packages prior to final storage.
Research and QA/QC Applications
The Heat Check SV is also used in research settings where consistent thermal data on experimental nuclear materials is critical. Its precise control and measurement capabilities support innovation in radiological instrumentation and materials science.
Competitive Advantages
- Small Footprint, Big Capability: Optimised for confined labs or transport to field sites.
- High Accuracy and Repeatability: Ensures confidence in data used for nuclear safety decisions.
- Compatible with Existing Infrastructure: Can work alongside gamma spectrometry to provide a full radiological profile.
- Minimised Human Intervention: Reduces risk of contamination and measurement error.
- Compliant by Design: Engineered to meet national and international waste handling and classification regulations.

Product FAQ's
The Heat Check SV provides accurate, non-destructive calorimetry measurement of radioactive waste to determine heat output from isotopic decay.
Yes. The system quantifies heat from alpha and beta decay sources such as plutonium-238, tritium, and strontium-90 with high accuracy.
Absolutely. Its compact, robust design allows for use in active nuclear facilities, decommissioning sites, or storage locations.
While gamma spectrometry identifies gamma emitters, the Heat Check SV complements this by quantifying total decay heat from alpha and beta emitters which gamma systems may miss.
Samples must be in sealed small-volume containers suitable for thermal analysis. The system accepts industry-standard packaging used in nuclear waste storage.
