Cohen proposes expanded research on small field-reversed configuration reactors, targeting fusion power between 0.5 and 50 MW and fuels that produce fewer neutrons. His white paper presents a research programme, identifying potential engineering advantages while specifying physics and technology questions that still require investigation. Priorities include current drive, kinetic modelling, plasma stabilization and heating, alongside the development of shielding for reactor components. Proposed direct electricity-conversion methods need testing; reduced neutron production does not remove the need for shielding. Cohen recommends beginning with specialized customers who lack alternatives, before competing in the broader electricity market.
