Tritium Handling and Containment

Tritium is processed in sealed, negative-pressure systems with getters, permeation barriers, and continuous cleanup.

Because tritium is a mobile gas that permeates metals and exchanges into water vapor, handling it is an exercise in containment and capture rather than shielding. The dose hazard from tritium is internal (inhalation or absorption), so the entire fuel cycle is built to keep it inside sealed systems and to recover any that escapes.

The containment toolkit

• Negative pressure: tritium zones held below ambient so leaks flow inward.
• Secondary enclosures: gloveboxes and double-walled piping around active components.
• Getters and molecular sieves: materials that trap tritium for recovery.
• Detritiation systems: convert and capture tritium from air and water streams.
• Permeation barriers: coatings and material choices that slow migration through walls.

The design goal is a closed loop: bred and burned tritium circulates within the plant, with cleanup systems recovering stray material back into the cycle. This both limits releases and conserves a scarce fuel. Workers interact with tritium systems through remote and glovebox operations under an ALARA program.

Routine emissions

Even well-contained tritium plants have small, permitted routine emissions, monitored continuously and kept well within regulatory limits. The strategy is capture-first: minimize what is emitted rather than dilute-and-disperse. See tritium monitoring and permeation control.

Handling tritium is a solved, industrial discipline drawn from decades of experience at existing facilities; Kronos applies it at a plant scale set by the small resident inventory.
