The tasks of the AEC-supported Gas-Cooled Fast Breeder Reactor (GCFR) program are program planning, core development, fuels and materials development, irradiation tests, and nuclear analysis and reactor physics. The status of the three volumes of the development program plan document for the GCFR demonstration plant is reported. Surveillance of materials included some recent information on cladding materials, which is summarized. The current irradiation test results and analyses are reported for capsule GB-9, which is operating very satisfactorily in ORR and has reached 43,000 MWd/Te. Plans for the irradiation of a similar but improved capsule (GB-10) are discussed. The status of the fast-flux experiment F-l (X094) in EBR-II and of the five F-l replacement rods is reported. Results of out-of-pile experiments to develop cladding temperature-monitoring techniques are discussed. Finally, the background and objectives of the GCFR critical assembly program are presented.
