Siemens Argonaut Reaktor-Graz, Nuclear research reactor at Technical University of Munich, Germany.
The Siemens Argonaut Reactor-Graz was a small research facility with a thermal power of about 1 kilowatt that used light water as a moderator and graphite reflectors to focus neutrons. The system was a compact design created specifically for teaching and scientific experiments.
The facility was built in the late 1950s as Germany's first nuclear reactor designed and constructed entirely by German scientists and engineers. It remained operational until 1968, representing an important milestone in the country's independent nuclear research capability.
The facility served as a teaching hub where nuclear engineering students gained hands-on experience with reactor operations and nuclear science. This educational mission shaped how a generation of researchers understood and worked with atomic technology.
The site is located in Munich and is no longer open to visitors, as the facility was completely dismantled. The area has been converted into public green space after all decontamination work was finished.
After shutdown, the reactor site was transformed into a green area that today reminds visitors of its former scientific role. This conversion shows how nuclear research facilities can be reintegrated into urban spaces for public use.
