Assembly and set-up of the CIEL project plasma facing components on Tore Supra

Tore Supra is the only superconducting Tokamak equipped to actively cooled plasma facing components. The CIEL project (composants internes et limiteurs) consists of a complete major upgrade of all the existing internal components (Fusion Engineering and Design 56–57 (2001) 117). This new device should enable removing 15 MW of convected flux on the toroidal pump limiter (TPL) and should sustain high radiated plasma power losses of at least 10 MW on the first wall during pulse length up to 1000 s. The associated primary pressurized water loop (3 MPa at 150 °C) has also been upgraded in order to be able to exhaust the injected power in a steady state configuration. The paper describes assembly operations during the fabrication and setting-up of plasma facing components as part of the CIEL project during the 2000–2002 shutdowns.
