Nuclear Industry

In no sector of engineering are reliable material properties data more important than in the field of nuclear energy. This refers to the different categories of materials for nuclear reactors and nuclear waste management such as cladding materials, absorbers, structural materials, fresh and spent fuels, and other waste forms.

The thermodynamic and thermophysical properties are the main focus of our product line for nuclear materials testing. These, of course, have to be completed by mechanical properties for establishing a comprehensive material properties data base.


Thermophysical properties are broadly defined as those parameters relating to the interaction of matter and energy. These properties can be divided into two groups: (1) thermodynamic properties which relate to thermodynamic equilibrium and (2) transport properties which involve the movement of heat, mass or electric charge. With Differential Scanning Calorimetry (DSC) we measure thermodynamic properties, such as specific heat and transition energetics, and with Dilatometry (DIL) we determine the thermal linear and volumetric expansion (ΔL/L0 and ΔV/V0), thermal linear and volumetric expansion coefficients (α and β) and density (d). Transport properties which include thermal conductivity (λ) and thermal diffusivity (a) are measured by LaserFlash Analyzers (LFA), by Heat Flow Meters (HFM), by Guarded Hot Plate Systems (GHP) and Hot Wire (TCT) techniques.
Our instruments cover a temperature range of -260°C to 2800°C and can be configured to operate in cold, fume hood, glovebox and hot cell environments.

We have the ideal solution for you!

Our product recommendation for you:
