| Abstract: | A series of mixed oxide UO/sub 2/-PuO/sub 2/ Liquid Metal Reactor (LMR) Fuel assemblies using D9 alloy cladding and/or ducts have been irradiated to high exposure in the Fast Flux Test Facility (FFTF) with very encouraging results. D9 is a titanium modified variant of 316 stainless steel. The highest burnup attained for 316 stainless steel clad driver fuel pins in FFTF has been achieved in an assembly with a cold worked D9 duct while assemblies which simultaneously utilize both D9 ducts and D9 clad pins have achieved burnups as high as 155 MWd/kgM with a corresponding fast fluence of 25 x 10/sup 22/ n/cm/sup 2/. The cold worked D9 ducts demonstrated less length increase and less dilation than their Cold Worked 316 SS counterparts. The D9 pins also showed less length and diameter increase than comparable 316 SS pins with less evidence of deformation due to interference between the pin bundle and the duct. Corrosion behavior at the inner and outer surface of the D9 cladding has proved to be very similar to that of 316 stainless steel. |
