The irradiation of two fuel pins containing thorium-plutonium oxide pellets is under way at the Halden research reactor in Norway. Thor Energy – which is leading the consortium carrying out the research – said this is the start of the third phase of a five-year trial-operation of thorium-based nuclear fuels. The thorium-MOX pellets were produced at the Institute for Energy Technology’s (IFE’s) nuclear fuel laboratory at Kjeller, near Oslo. The pellets were produced with thorium oxide provided by Solvay. These were loaded into two fuel pins and assembled into a test rig – together with a reference pin containing uranium oxide pellets – that was loaded into the OECD Nuclear Energy Agency’s Halden research reactor.
