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
