Anton Paar MCR 302 Rheometer with CTD1000

The Anton Paar MCR 302 is a modular rheometer for rotational and oscillatory rheological measurements. Integrated with the CTD1000 Convection Temperature Control Device (-100°C to 1000°C), it enables high-temperature fluid characterisation, essential for molten salt reactors (MSRs), pyroprocessing, and nuclear waste studies.

Capabilities
     • Molten Salt & High-Temp Rheology: Measures viscosity, flow behaviour, and phase transitions of molten salts and reactor coolants.
     • Shear & Oscillatory Testing:
         o Rotational Mode: Determines shear viscosity and flow curves for nuclear fuel cycle fluids.
         o Oscillatory Mode: Analyses storage (elastic) and loss (viscous) moduli for structural integrity.
     • Controlled Atmosphere Testing: Allows studies under inert, oxidising, or reducing gases to simulate real-world reactor conditions.
     • Cone/Plate & Parallel Plate Geometries: Enables precise shear stress and rate control for complex fluids.

Technical Specifications
     • Temperature Range: -100°C to 1000°C with convection heating for uniform distribution.
     • Torque Range: Min. 0.01 µNm, Max. 230 mNm, enabling precise viscosity measurements from low-viscosity liquids to high-viscosity slurries.
     • Shear Rate Range: 10⁻⁵ s⁻¹ to 10⁴ s⁻¹, covering slow-flowing to highly dynamic fluids.
     • Frequency Range: 10⁻⁷ Hz to 100 Hz, supporting broad oscillatory testing.

This high-precision rheometer enables detailed rheological analysis of molten salts, nuclear coolants, and high-temperature materials, supporting reactor development, pyroprocessing, and nuclear waste handling.
