Tritium-Handling Standards

Tritium is a low-energy beta emitter that must be contained, accounted for, and monitored to established practice.

Handling a mobile, radioactive isotope

Tritium is a radioactive isotope of hydrogen that emits low-energy beta particles and is chemically hydrogen — it permeates materials and mixes into water. It is not an external-radiation hazard through skin, but it must be contained to prevent inhalation or ingestion. Handling it draws on decades of established practice at tritium facilities worldwide.

Controls Kronos designs to

• Multiple containment barriers with monitored interspaces.
• Materials selected for low tritium permeability, with recovery systems on likely pathways.
• Continuous air and effluent monitoring against radiation-protection limits.
• Rigorous accountancy — every gram tracked — which also supports safeguards transparency.

Why it is central to the breeder

The breeder both breeds and burns tritium and produces a tritium-class product on the order of 4 kg/yr, so tritium handling is not a side system — it is core plant infrastructure. It also determines the helium-3 product, since helium-3 arises from tritium decay and must be captured. Handling readiness is therefore inseparable from the breeder's product case, and it is designed to established standards rather than improvised.
