Australia’s first nuclear reactor retires after powering science for 70 years
ANSTO begins decommissioning Australia’s historic HIFAR reactor, marking a milestone in nuclear history after nearly 70 years.
Australia’s Nuclear Science and Technology Organisation (ANSTO) has embarked on a major decommissioning project for the country’s first nuclear research reactor.
Located at Lucas Heights, HIFAR was opened back in 1958 by Australian Prime Minister Sir Robert Menzies. It remained operational for nearly 50 years before being replaced by ANSTO’s current research reactor, OPAL, in 2007.
The commencement of the decommissioning project follows a license issued in late 2024 by the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) for the initial stages of dismantling.
ANSTO CEO Shaun Jenkinson reflected on the significance of HIFAR, stating, “Australia’s nuclear age was formally ushered in with the commissioning of HIFAR, which has remained an iconic landmark on ANSTO’s campus.”
“The distinctive white circular steel frame of the HIFAR facility has been a prominent fixture of Lucas Heights and across the valley here in southern Sydney for nearly 70 years,” he added.

The decommissioning of HIFAR is a complex, multi-stage process that will be carried out in line with international best practices.
ANSTO’s extensive experience in radiation protection, safety, and engineering will play a crucial role in ensuring safe and efficient decommissioning.
