The Power-Exhaust Problem
Getting the fusion power out without destroying the components it flows through.
- Challenge
- Concentrated heat flux
All the power a plasma produces must eventually leave through its surfaces — and concentrating it on a small divertor can exceed material limits. Managing power exhaust, chiefly by radiating a large fraction before it reaches the target, is one of fusion's hardest engineering problems. HYPERION leans on a high radiated fraction, a named gate.
The low-neutron burner's linear geometry gives it a gentler exhaust problem.
Getting the fusion power out without destroying the components it flows through is one of fusion's hardest problems, because concentrating it on a small divertor can exceed material limits. Radiating most of the exhaust before it lands is the primary tool — the basis of HYPERION's high-radiated-fraction divertor and a genuine performance gate.
Common questions
All the exhaust power funnels toward a small divertor area, where it can exceed what any material survives. Getting the power out without destroying the components it flows through is a genuine engineering limit.
By radiating most of the exhaust power before it reaches the targets, spreading it over the whole wall. Achieving that high radiated fraction while keeping the core clean is a named performance gate.
