Aspects of an inertial-confinement, fusion reactor that uses an energy release {approx gt}10{sup 11} joules are discussed. The large energy release makes possible direct conversion of the fusion neutrons' energy after nuclear heating of an evaporated blanket to the plasma state. Surface damage by charged particles is avoided and structural damage by neutrons is alleviated. Complex fuel assemblies and other expandable parts may be used as a result of the high monetary value of the energy release.
