Fusion Reactor and Test Cell Configuration^a

Remote maintenance and repair considerations will play a major role in determining the design and layout of next-generation fusion devices, including the buildings and facilities supporting the nuclear operation of those devices. The reactor/test cell described in this paper represents a “nominal copper” TFCX (Tokamak Fusion Core Experiment) concept that emphasizes an integrated approach to the design of the experimental device and its supporting facilities. This configuration is unique with respect to other TFCX concepts in that it promotes the use of a modular design with readily replaceable stand-alone sectors, integrates the machine and test cell structures, incorporates a facility arrangement that results in a smaller overall facility footprint, reduces the transportation path of activated hardware, and allows access to three sides of the test cell facilities.
