PhD thesis with NIRAS/ONDRAF

To advance research related to waste and disposal issues NIRAS/ONDRAF and SCK•CEN propose several joint PhD opportunities.

Preparing your doctoral thesis at the Belgian Nuclear Research Centre in collaboration with NIRAS/ONDRAF offers you the best of both worlds: you stay in close contact with the academic world and you enjoy a unique international research environment, with advanced nuclear experimental facilities and top-level guidance from our experts.

PhD students should register at a pre-defined university, depending on the topic of their PhD. Although they are doctoral students at the university, they are based in Mol for the greater part of the time.
