Effects of initial stoichiometry on the character and extent of fuel-cladding chemical interaction (FCCI) were established for mixed-oxide fuels irradiated to peak burnups of approximately 3.6 at.%. The present LMFBR design basis considers an initial reduction of 50 microns (2 mils) in cladding thickness to compensate for possible FCCI. This thickness loss represents a significant part of the total cladding wastage allowance for the LMFBR reference fuels design. The reduction or elimination of FCCI would allow a corresponding reduction in cladding thickness resulting in an improvement in the breeding ratio and a reduction in system doubling time.
