====Metallic fuel====
Metal fuel with a sodium-filled void inside the cladding to allow fuel expansion has been demonstrated in EBR-II. Metallic fuel makes [[pyroprocessing]] the reprocessing technology of choice.{{citation needed|date=March 2014}}

Fabrication of metallic fuel is easier and cheaper than ceramic (oxide) fuel, especially under remote handling conditions.<ref name=PE/>

Metallic fuel has better [[heat conductivity]] and lower [[heat capacity]] than oxide, which has safety advantages.<ref name=PE/>
