What is HYPERION?

HYPERION is Kronos's breeder machine: a compact spherical tokamak (Q = 3.424, 88.7 MW) whose product is neutrons, tritium (4.0 kg/yr/yr) and helium-3, not grid electricity. It fuels the burner and is a saleable neutron source in its own right.

Building it first is what lets Kronos earn before net electricity is proven.
