Description

The French Tore Supra tokamak is upgraded in an x-point divertor fusion device in the frame of the WEST (W-for tungsten-Environment in Steady-state Tokamak) project, launched in support to the ITER tungsten divertor strategy. The WEST project aims to test actively cooled tungsten Plasma Facing Units (PFU) under long plasma discharge. As the existing cooling loop B30 cannot ensure the cooling of the W divertor elements under ITER nominal conditions, a new pressurized water loop must be designed to exhaust all the heat coming from the plasma and transmitted to the in-vessel components. It includes additional piping networks of around 50m33 connected to the existing loop in order to cool components such as stainless steel vessel protection panels, upper and lower divertor coper coils, baffle, bumpers and ripple protection. During plasma operation, the water inlet temperature is 70 °C and the pressure at the inlet of the pump is 2.4 MPa while baking is performed at 200 °C and 2MPa to achieve the outgassing of components inside the vacuum vessel. As the pressure drop of the divertor coils is higher than the pressure drop of the other PFCs, the cooling of these coils is ensured by an independent water loop with a new centrifugal pump. This paper presents the thermo-mechanical analysis of this system including piping stress and supports analysis according to CODETI standards.
