Tritium Safety

Tritium is the breeder's one genuinely radioactive material. Kronos names it and engineers for it.

Tritium is a low-energy beta emitter that is hazardous chiefly if inhaled or ingested. Plants manage it by keeping inventories low (HYPERION's startup inventory is 6.47 kg), using permeation barriers, multiple containment, and continuous monitoring.

Because the burner runs low-neutron D–³He, tritium handling is overwhelmingly a breeder consideration, not a burner one.

Licensing-relevantTritium handling and accountancy are among the breeder's named gate items, treated as a real licensing task.

Tritium is the breeder's one genuinely radioactive material, a low-energy beta emitter managed with low inventories (6.47 kg startup), permeation barriers, layered containment and continuous monitoring. Because the burner runs low-neutron D–³He, tritium handling is overwhelmingly a breeder consideration, and Kronos names it as a licensing-relevant gate.

Common questions

Is tritium a showstopper?

No — it is a handled hazard managed with low inventories, permeation barriers and monitoring. The breeder breeds its own, so supply is a feature.
