Environments
Supercritical Water
Experiments can be performed in two supercritical water autoclaves.
- Up to 600°C
- High-performance liquid chromatography pump provides flow rates up to 100 mL/min at up to 27.5MPa
- Water conductivity monitored at the inlet and outlet
- Dissolved Oxygen monitored at the inlet and outlet to 5 ppb
- Water chemistry control via mixing column
Light Water Reactor Environments
Experiments can be performed in two CERT systems in simulated BWR or PWR environments.
- Water temperatures at 288-360°C
- Water conductivity
- Monitored at the inlet and outlet
- Controlled via dilute acidic solution in mixing column
- Dissolved Oxygen
- Monitored at the inlet and outlet
- Controlled from 8 ppm down to 1 ppb
- Additions of boric acid and lithium hydroxide to simulate PWR environment
High Temperature Steam
Single specimen CERT tests can be performed in a high temperature steam environment.
- Steam temperatures up to 550°C
- Desired corrosion potential can be obtained by controlling the H2/H2O partial pressure ratio
- Hydrogen partial pressure is controlled using custom Ar/H2 gas mixtures and a mass flow controller
- Water vapor partial pressure is controlled using a steam bath in combination with dew point meters
Constant Load Testing
Creep tests can be performed in a two-liter constant load system. This system allows for simultaneous testing of three samples under controlled load conditions.
- Simulated BWR or PWR conditions (288-360°C)
- High temperature gas (550°C)
- Creep rates lower than 10-9 s-1 can be reliably measured
