RB	Belgrade	Heavy water		Temporary shutdown	0.00	1958-04-29		Vinča Nuclear Institute, Vinča	At the beginning, the RB reactor was designed and constructed as an unreflected zero power heavy water - natural uranium critical assembly. First criticality was reached in April 1958. Later, the 2% enriched metal uranium fuel and 80% enriched UO₂ fuel were obtained and used in the reactor core. Modifications of the reactor control, safety and dosimetry systems (1960, 1976, 1988) converted the RB critical assembly to a flexible heavy water reflected experimental reactor with 1 W nominal power, operable up to 50 W. Several coupled fast-thermal systems were designed and constructed at RB reactor in the early 1990s, for research in fast reactors physics.

Civilian (private and university) research and test reactors formerly licensed to operate

Research and test reactors under decommission orders or license amendments are authorized to decontaminate and dismantle their facility to prepare for final survey and license termination. Research and test reactors with possession-only licenses are not authorized to operate the reactor, only to possess the nuclear material on-hand. They are permanently shut down.

Civilian (private and university) research and test reactors in construction

Executive Order 14301 created DOE's Reactor Pilot Program, expediting advanced reactor testing outside national labs, targeting criticality for three test reactors by July 4, 2026. 11 Reactors are being developed as part of this program. This list is of the reactors already in construction.
