List of nuclear research reactors

This article is about nuclear fission research reactors. For fusion research reactor lists, see List of nuclear reactors. For commercial power reactors, see List of commercial nuclear reactors and List of nuclear power stations.

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.

This is an annotated list of all the nuclear fission-based nuclear research reactors in the world, sorted by country, with operational status. Some "research" reactors were built for the purpose of producing material for nuclear weapons.

Notes: The main uses of the current OPAL reactor are:

• Irradiation of target materials to produce radioisotopes for medical and industrial applications
• Research in the fields of materials science and structural biology using neutron beams and its sophisticated suite of experimental equipment
• Analysis of minerals and samples using the neutron activation technique and the delay neutron activation technique
• Irradiation of silicon ingots in order to dope them with phosphorus and produce the basic material used in the manufacturing of semiconductor devices

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.
