Remote-Handling Systems
Activated, high-dose components cannot be maintained by hand; remote handling replaces the first wall, blanket modules, and center-post.
Hands-off by necessity
After operation, the breeder's in-vessel components are activated and sit in radiation fields too high for hands-on work. Maintenance and replacement are therefore done remotely, with manipulators and tooling operated from outside the machine. Remote handling is not a convenience; it is the only way to service the components that wear out.
What gets replaced
- First-wall tiles and plasma-facing armor, as they erode.
- Blanket modules, over life and for upgrades.
- The center-post, on its short ~0.01 fpy interval.
- Divertor targets under concentrated exhaust load.
Designed into the machine
Remote handling only works if the machine is built for it: access routes, standardized module interfaces, connections that a manipulator can make and break, and viewing and metrology to guide the work. These are top-level design requirements, decided early, because a machine not built for remote handling cannot be maintained at all once activated.
Why it is central here
The breeder's short-lived components — center-post, first wall, divertor — make remote handling a defining system rather than a support function. The replacement cadence, hot-cell handling, and remote joining pages describe how the machine turns unavoidable component wear into a scheduled, executable maintenance program.
Rescue and recovery
A remote-handling plan must include recovery from its own faults: a manipulator that stalls with a component half-removed cannot be reached by hand in an activated vessel. Designs therefore build in redundant or rescue tooling and viewing, so a stuck operation can be recovered remotely rather than stranding the machine mid-maintenance.
This page documents a design and simulation study, not a built machine. Construction begins Q2 2027; first-of-a-kind first tritium is targeted near 2030. Figures are computed, reproducible targets, not measurements.
