Moltex Energy Canada has validated an innovative technology that could transform nuclear waste management by consuming most of the transuranic elements present in used fuel bundles from Canada’s Candu reactors and using them as fuel.

Moltex said it has validated its “waste to stable salt” (Watss) process on used fuel bundles from a commercial reactor in Canada through hot cell experiments, marking what it called a pivotal moment in closing the nuclear fuel cycle and advancing next-generation nuclear sustainability.

According to Moltex, the advancement vastly reduces nuclear waste volumes.
