Hyperion's tritium output is specified as a range, 1.87 to 4.0 kg per year, sized to the customer's requirement rather than to a physics maximum. Designing to a requirement is a different discipline from designing to a peak.
Because breeding ratio is a lever, tritium yield can be dialed to a target. Hyperion spans 1.87-4.0 kg/yr by choice, matching the machine to the national requirement instead of chasing the largest number the plasma could produce.
A requirement-sized machine is a smaller, cheaper, more licensable machine than a maximised one. It also means the tritium inventory on site stays inside existing civil licensing practice, which is a schedule advantage, not just a safety one.
