ABS>The tasks of the Gas-Cooled Fast Breeder (GCFR) program are program planning, core development, out-of-pile heat-transfer and fluid-flow tests, development of a pressure-equalization system for fuel rods, fuels and materials development, and nuclear analysis and reactor physics. The core development task is to establish criteria for the design of the GCFR fuel, control, and blanket element assemblies. Analytical methods are being developed for predicting fuel- rod response to transient conditions and for treating thermal-hydraulic and structural analyses of fuel assemblies. For the heat-transfer and fluid- flow tests of fuel assemblies, planning of the test program and test facility was initiated. The development work on the pressure-equalization system included designing the test assemblies for static adhesion tests and seal leakage tests, development of the fuel-rod manifold, and development of an analytical model for designing monitoring instrumentation. In the fuels and materials task, the status of the thermal and fast-flux irradiation programs and analyses of data from these experiments are given. Nuclear analysis and reactor physics work included GCFR critical experiment planning, surveillance of LMFBR critical assembly experiments, and methods development. (auth)
