Located at the Helmholtz-Zentrum Berlin (HZB) in Germany, BER II was a pool-type research reactor dedicated to neutron scattering for civilian scientific purposes. It operated for several decades before its permanent shutdown in December 2019. Its history reflects a key role in advancing material sc

Located at the VTT Technical Research Centre in Otaniemi, Espoo, Finland, FiR 1 is a 250 kWth TRIGA Mark II research reactor. It was used for civilian purposes such as neutron activation and boron neutron capture therapy (BNCT) before its permanent shutdown in 2015. The reactor no longer operates bu

Based in Halden, Norway, the Halden Boiling Water Reactor (HBWR) was a unique heavy water boiling research reactor operated by IFE. It was significant for international collaboration, involving 19 member countries, and focused on fuel testing and materials research over its 59-year operational histo

The HIFAR research reactor was situated at Lucas Heights in New South Wales, Australia, and operated by ANSTO. It was a cornerstone of Australian nuclear research for isotope production and neutron scattering over its 49-year operational history until its shutdown in 2007, when it was replaced by th

Located at the Nuclear Scientific Research Center in Tajura, Libya, the IRT-1 is a 10 MWth pool-type research reactor. It played a role in training and neutron activation studies during its operational period. The reactor was permanently shut down in 1989 under IAEA supervision.

The Japan Materials Testing Reactor (JMTR) is located in Oarai, Ibaraki, Japan, and was operated by the Japan Atomic Energy Agency (JAEA). It was historically significant for materials testing and fuel irradiation studies, contributing to the development of civilian nuclear technologies. The reactor

Situated at Chalk River Laboratories in Ontario, Canada, the NRU was a heavy water research reactor with a thermal power of 135 MWth, once the world’s largest producer of Mo-99 for medical use. Its significance stems from over 60 years of contributions to isotope production, materials testing, and n

Located at the CEA Saclay site in France, ORPHEE was a pool-type research reactor moderated by heavy water, focused on neutron scattering and condensed matter physics. It played a notable role in scientific research for approximately 40 years before its permanent shutdown in 2019. Its contributions

The Portuguese Research Reactor (RPI) was located at Instituto Superior Técnico in Lisbon, Portugal, and operated by IST/LPSR. This 1 MWth pool-type reactor supported neutron activation and training until its permanent shutdown in 2013. It played a role in advancing civilian nuclear research and edu

PROTEUS, a zero-power critical assembly, was located at the Paul Scherrer Institut (PSI) in Villigen, Switzerland. It played a key role in reactor physics and criticality experiments for civilian nuclear research until its permanent shutdown in 2011. With a thermal power of just 0.001 MWth, it suppo

Located in Diliman, Quezon City, Philippines, the PRR-1 is a pool-type research reactor managed by the Philippine Nuclear Research Institute. It was used for training and neutron activation studies before being permanently shut down in 1988 due to safety and funding concerns. The reactor no longer o

The R2-0 research reactor was located at Studsvik in Nyköping, Sweden, and was operated by Studsvik AB. As the last operating research reactor in Sweden, it was significant for materials testing and training until its permanent shutdown in 2005. This 0.05 MWth pool-type reactor contributed to civili

UUJV (IRT-R1000) was located in the Havana area of Cuba and operated by CPHR. This Soviet-supplied pool-type research reactor, used for training and research, was operational from approximately 1968 to 2000. It is now permanently shut down, marking the end of its contribution to civilian nuclear res
