What is the Synroc Waste Plant?

ANSTO is developing a Synroc plant to manage the by-products of past, current and future manufacture of nuclear medicine. 


The first of its kind, the plant will showcase this technology to the rest of the world.


What is Synroc?

The term Synroc was derived from ‘synthetic rock’, as the method mimics the natural way rocks are able to lock up radioactive elements for hundreds of thousands of years.

Developed by scientists at ANSTO and the Australian National University, this innovative technology has been shown to significantly reduce the volume of nuclear by-products compared with other waste management methods.

ANSTO’s Synroc team has developed a range of waste form solutions involving the use of Hot Isostatic Pressing (HIP) technology where components are placed in a sealed can inside a furnace and compressed to maximum density and minimise disposal volume. 


What is Hot Isostatic Pressing (HIP)?

HIP technology consists of a pressure vessel containing a furnace. The components are placed in a sealed stainless steel can inside the furnace which is heated and pressure applied, using argon gas, to create the synthetic rock and minimize disposal volume.
