Lithium-6 & the No-Breeding-Claim

Some concepts invoke lithium-6 breeding. Kronos deliberately makes no such claim — its fuel is staged D–³He, and it says so plainly.

Lithium-6
A neutron-absorbing isotope used for tritium breeding
Some concepts
Invoke p–⁶Li or Li breeding in the fuel story
Kronos position
Makes NO breeding claim on lithium
Actual fuel
Staged, catalyzed D–³He

Lithium-6 is the isotope that D–T reactors use to breed tritium, and it appears in various advanced-fuel proposals — including proton–lithium-6 reactions. Kronos is deliberately clear about what it does not claim: the MetroVolt fuel cycle is staged, catalyzed D–³He, and the company makes no lithium-breeding claim and does not describe its fuel as "lithium-6 and helium-3."

This matters because overstated fuel-cycle claims are a common way fusion proposals lose credibility. Kronos's helium-3 comes from in-situ D–D breeding, not a lithium blanket, and the p–⁶Li channel is examined and set aside rather than leaned on. Stating the fuel path precisely — and refusing the breeding claim it doesn't have — is part of the same "show your work" discipline as the pre-registered predictions.
