HIGH PRESSURE COOLING MANIFOLD
The water supply manifolds are located on the components facing the plasma of the lower divertor of the WEST (W (Tungsten) Environment Steady-state Tokamak) project.
The pressurized water loop extracts the thermal power received and transfers this thermal power to a secondary circuit via a heat exchanger.

HIGH PRESSURE COOLING MANIFOLD
The mission's challenge
The first part produced using additive manufacturing for the reactor, it required significant technical qualification efforts.
The high pressure combined with operating temperatures required advanced fluid and mechanical analyses, performed using ANSYS Workbench and Fluent.
- Fluid analysis: pressure distribution, pressure losses, flow velocity.
- Mechanical analysis: static, pressure, thermoelastic.
