The irradiation program for the development of fuel elements for the gas- cooled fast breeder reactor GCFR is discussed. Thermal flux irradiations included two vented mixed-oxide fuel rods, one irradiated to 54,000 MWd/Te and one that attained a burn-up of 20,500 MWd/Te. These experiments provided design data and confirmed the feasibility of the vented fuel concept. Fast flux irradiation of an assembly of seven encapsulated mixed-oxide sealed fuel rods to planned burnups up to a maximum of 100,000 MWd/Te in progress. Interim examinations at 25,000 and 52,000 MWd/Te showed that all rods remained intact even at the maximum cladding outside surface temperature of 780 deg C (1436 deg F). A second capsule assembly will be irradiated in a fast flux starting early in 1974. (auth)
