Fixed Bed Nuclear Reactor
passively cooled nuclear reactor

The Fixed Bed Nuclear Reactor (FBNR) is a simple, small, proliferation resistant, inherently safe and passively cooled nuclear reactor with reduced environmental impact. The reactor is being developed under the auspice of the International Atomic Energy Agency. Its science and technology is in the public domain.
The main developer of the Fixed Bed Nuclear Reactor is the Federal University of Rio Grande do Sul. Several international institutions have shown interest in participating in this project, including Imperial College of the University of London, Institute of Theoretical and Experimental Physics (ITEP) and the Institute of Physics and Power Engineering (IPPE) in the Russian Federation.
The design underwent 3D analysis and testing and results were published in 2020.
This brief starts where responsible research should: with the source description of “Fixed Bed Nuclear Reactor” as passively cooled nuclear reactor. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as passively cooled nuclear reactor. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 18, 2023. The linked authority identifier is Q3931177. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2020.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
