Computing for Remote Maintenance
Activated components must be maintained without direct human access, so remote handling relies on simulation, planning, and precise models.
Why remote
After operation, components near a D-T plasma become activated and cannot be approached directly for some time. Maintenance must be done by remote handling equipment. Because the environment is unforgiving and access is limited, every operation is planned and rehearsed in simulation before it is performed for real.
How computing supports it
- Plan and rehearse handling sequences in a physics-accurate digital twin.
- Check reach, clearance, and collision along every path.
- Schedule maintenance using predictive estimates of what needs attention.
- Track activation and dose so operations stay within limits.
Simulate first
A remote operation that fails partway can strand a tool in an inaccessible space. Simulating the full sequence first, against an accurate model of the as-built machine, catches interferences and errors before they happen. The twin is the rehearsal environment.
Activation awareness
The dose field around components comes from neutronics and decays with time. Maintenance planning uses this to sequence operations for lower dose and to schedule work when activation has dropped, tying remote handling to the safety analyses.
For Hyperion
The Hyperion breeder is a compact D-T machine, so its components are both highly activated and tightly packed, making remote maintenance planning especially demanding. The lower neutron fraction of the D-3He burner changes but does not remove this need.
Feeding the record
Every planned and executed operation is logged, feeding maintenance models and safety records.
