Partial reuse assumes that all foreseen activities will be transferred to the Shipping
Area and the Auxiliary Building, while all other buildings and areas will be
decommissioned to unrestricted release. After cessation of any remaining activities,
the entire BR3 site would be released to unrestricted use.

6.5.14 Graz Reactor, Austria (Kainz, 2009)
The Reactor Institute Graz, attached to the University of Technology Graz, Austria,
operated a low power Siemens-ARGONAUT-Type reactor for education and training.
The reactor was finally shut down on August 31, 2004. As the shielding consisted of
modular concrete blocks (Fig. 6.33) the dismantling of this reactor was exceedingly
smooth. Besides, due to the low power level only very few reactor components were
slightly activated and were considered low active waste. The reactor building was
rehabilitated in 2006 and used for other laboratories. In the ground floor there is a
welding laboratory and on the first floor a flight simulator.

6.5.15 University of Washington Reactor WA, USA (Save The
Reactor, 2016)
In contrast with many successful redevelopment projects, the University of Washing-
ton reactor, Seattle, WA tells a different story. Built the Nuclear Reactor Building
housed the University of Washington nuclear program. It was designed by an
