Chemical and Material Safety
The plant's chemical hazards — lithium, beryllium, coolants — are conventional industrial hazards managed by standard practice.
Beyond radiation, a fusion plant contains chemical hazards common to heavy industry, plus a few specific to the breeder blanket. None of these couples to the radiological case in a way that creates a large release; they are managed with established industrial chemical-safety practice.
The main chemical hazards
- Lithium (breeder blanket): reactive with water and air — handled in inert, dry systems.
- Beryllium (neutron multiplier): toxic as fine dust — controlled with containment and respiratory protection.
- Coolants and working fluids: conventional thermal and chemical management.
- Cryogens and gases: covered under cryogenic and gas safety.
Lithium and beryllium appear specifically in the breeder (Hyperion) blanket, where lithium breeds tritium and a beryllium (or other) multiplier boosts neutron yield toward the target tritium breeding ratio (studied at 1.1 / 1.5 / 1.8). Their hazards — lithium's reactivity, beryllium's toxicity — are well characterized and handled with inerting, containment, and worker protection. See breeder blanket safety and beryllium handling.
The burner is simpler
The burner (Aegis / MetroVolt) has no breeding blanket, so it avoids the lithium and beryllium inventories entirely; its chemical hazards reduce to deuterium (flammable) and conventional plant chemicals. See deuterium safety.
Chemical safety is standard industrial practice applied to a modest, well-understood inventory.
