“…The WEST tokamak is the result of a deep transformation of the Tore Supra tokamak [1,6,7]. The diverted configuration has been achieved by inserting poloidal field coils inside the circular vacuum vessel [8] and increasing the aspect ratio from 3.3 up to 5-6. The constraint to integrate ITER divertor vertical target technology at full scale led to the choice of a single quasi horizontal target (tilted at −22 • with respect to the horizontal axis) that collects both strike points.…”

WEST is an MA class superconducting, actively cooled, full tungsten (W) tokamak, designed to operate in long pulses up to 1000 s. In support of ITER operation and DEMO conceptual activities, key missions of WEST are: (i) qualification of high heat flux plasma-facing components in integrating both technological and physics aspects in relevant heat and particle exhaust conditions, particularly for the tungsten monoblocks foreseen in ITER divertor; (ii) integrated steady-state operation at high confinement, with a focus on power exhaust issues. During the phase 1 of operation (2017–2020), a set of actively cooled ITER-grade plasma facing unit prototypes was integrated into the inertially cooled W coated startup lower divertor. Up to 8.8 MW of RF power has been coupled to the plasma and divertor heat flux of up to 6 MW m−2 were reached. Long pulse operation was started, using the upper actively cooled divertor, with a discharge of about 1 min achieved. This paper gives an overview of the results achieved in phase 1. Perspectives for phase 2, operating with the full capability of the device with the complete ITER-grade actively cooled lower divertor, are also described.

From 2012 to 2016, the Tore Supra tokamak was upgraded in an x-point divertor device within the frame of the WEST project. A huge design activity was made to modify the whole configuration of Tore Supra including the invessel components. Some of the most noticeable changes are the addition of inner divertor coils inside the vacuum vessel and the replacement of all plasma facing components. Fitting all the new components in a previously existing environment was probably one of the major challenges of the project. To improve the assembly plan and the design of toolings, Virtual Reality (VR) was introduced in the design process. For complex assembly operations, simulations were developed for VR headsets from CAD models. From the requirements expressed by the design team, the VR engineers developed dedicated tools to address the specific issues. Engineers, designers and operators were then able to experience the assembly conditions in a 3D 360° real size immersive environment and interact with the models thanks to a large set of dedicated tools which are developed in the VR lab. This approach showed impressive results for issues such as accessibility, complex kinematics of large components and design of handling tools. It allowed reducing the number of mock-ups and helped the WEST assembly team to reduce the number of unforeseen assembly issues. It was for example used to simulate the assembly of the divertor: insertion through the ports, toroidal displacement on rails, and assembly with gaps lower than 1mm. Virtual Reality will also provide innovative solutions to help designers in the anticipation of challenges linked to operation of a nuclear facility: operator's training for nuclear maintenance, virtual mock-ups for qualification of maintenance, maintenance scenario optimization with real time simulations... A first module plotting the dose rate is currently being tested. On the one hand, it would for example allow designers to improve the design by adapting maintenance operations to any complex 3D map of dose rate, and on the other hand, it would permit workers to train for operations in radioactive environments (showing no go areas, hot spots…).
