An aluminum-nickel alloy-clad ceramic-fueled plate of the BORAX-IV type was examined destructively after irradiation to a maximum burn-up of 7.800 Mw days per ton in the circulation water loop in the MTR. Irradiation was at 600 psig and 465 deg F. with local boiling in the area of highest neutron flux and a maximum heat flax of 500.000 Btu/(hr) (ft/sub 2/). The specimen performed satisfactorily in spite of several factors which made conditions more severe than those expected to exist in a reactor fueled with this type of element. The corrosion rate of the aluminum-nickel cladding on the element was approximately 10 mils per year. Oniy slight breakup of the ceramic pellet fuel was experienced and there was no evidence that the degree of cracking was influenced to any appreciable extent by exposure to radiation. (auth
