Deuterium–Tritium vs Advanced Fuels

The field's central fuel divide — and why Kronos runs both sides of it.

Mainstream

D–T

Advanced

D–³He, p–¹¹B

Kronos

Both, by purpose

Most fusion uses D–T for its unmatched reactivity, accepting a heavy neutron load (79.7%) and a steam cycle. A minority pursue low-neutron 'advanced' fuels (D–³He, p–¹¹B) for cleaner operation and direct conversion, accepting much higher temperatures. The two camps rarely overlap.

Kronos runs both: D–T in the breeder to make fuel and neutrons, and low-neutron D–³He in the burner to make clean electricity — capturing each fuel's advantage where it fits.
