These coolants are essential in fusion reactors to extract heat and breed tritium, but their corrosive nature threatens the integrity of the structural materials used.

The proposed approach would still use deuterium and tritium, which are generally accepted as the most promising pair of fuels for fusion energy production.

Researchers, working on nuclear fusion, are fusing tritium and deuterium together to maximize the amount of energy created in one small area.

Records show that from the 1940s through the 1960s, it was not uncommon for local hospitals, labs and other industrial operations to dispose barrels of tritium, carbon-14 and other similar waste at sea.

The NRC says tritium spills happen from time to time but typically don’t affect public health or safety.
