A large white cylindrical containment building rises above a curved glass-walled auxiliary plant room at ground level. Cracked asphalt spreads across the forecourt. Yellow bollards mark vehicle paths. To the left, metal-clad service buildings with corrugated sheeting stand two storeys high. A brick structure on the right shows black-and-yellow hazard striping on its bollards. Steel ladders and safety railings climb the containment vessel. Overcast sky presses low. HIFAR, the High Flux Australian Reactor, operated at Lucas Heights from 1958 until its permanent shutdown in 2007. The auxiliary plant room housed compressors, pumps and chillers that maintained precise environmental conditions inside the reactor building. The brick annexe, added in the 1990s, provided power distribution through a dedicated cable penetration point. ANSTO decommissioning of the facility continues.
