Dynamic and static corrosion tests on 8001 Al were completed. Annealing of 1100 cladding on 5083 and M400 cladding on X2219 were tested at 500°C, and investigation continued on producing X8101 Al alloy cladding in tube plates by extrusion. Boiler fuel element capsule irradiation tests and subassembly tests are described Heat transfer loop studies and fuel fabrication for the critical facility are reported. Boiler fuel element mechanical design and testing progress is described. and the superheater fuel element temperature evaluating routine is discussed. Low-enrichment superheater fuel element development included design studies and stainless steel powder and UO₂ powder fabrication studies Reactor Mechanical Studies. Research is reported on vessel and structure design, fabrication, and testing, recirculation system design, steam separator tests, and control rod studies. Reactor physics studies are reported on nuclear constants, baffle plate analysis, comparison of core representations, delayed neutron fraction. and shielding analysis of the reactor building. Reactor and system dynamics and critical experiments were also studied. Progress is reported on recombiner.
