Abstract
Techniques are described for automatically removing and replacing components, including a vacuum vessel, from a tokamak. The inventors have recognized that schemes for automatically removing and replacing components from a tokamak should preferably be simple (e.g., using proven equipment to perform a series of non-mechanically complex tasks) and have a very low risk of damaging components. Techniques described herein may include splitting a tokamak into multiple pieces, separating the pieces, and removing the now separate pieces of the vacuum vessel from within the pieces of the tokamak. A new vacuum vessel can be inserted in multiple pieces and the tokamak rejoined to complete the replacement process.
