That fact sheet seems internally contradictory. Quote:
”As part of this commitment to nuclear stewardship, Australia has committed to managing all radioactive waste generated through its nuclear-powered submarine program, including spent nuclear fuel, in Australia.”…..
”Australia will not enrich uranium or reprocess spent fuel as part of this program”…
To be clear, spent HEU fuel rods contain unspent weapons grade highly enriched uranium and plutonium. The idea of storing spent rods unprocessed indefinitely in Australia seems mad, particularly as there are other uses for it elsewhere. That’s ignoring the reaction by the other NPT signatory nations and the security risks.
