On-orbit Nuclear Power Concepts Workshop

ellite nuclear power systems. Our focus is on producible, cost-effective nuclear reactors � not bespoke designs suited for a one-time demonstration. DARPA TTO and the Department of Energy (DOE) will also hold a workshop to establish a common understanding of on-orbit nuclear power technology and cha

llenges, facilitate community interactions and collaboration, and identify key technology risk areas that, if addressed, would enable practical implementation of on-orbit nuclear power. The workshop will be held on April 21-22, 2026 at the
