Irradiation of a 19 pin subassembly with mixed carbide fuel in KNK II
The presentation deals with the fabrication, irradiation and nondestructive postirradiation examination of LMR fuel pins with mixed (U, Pu)-carbide fuels. Fuel composition varied in a wide range of tolerances with respect to oxygen and phase content and microstructure. The 19 carbide pins were irradiated in the fast neutron flux of the KNK II reactor to a burnup of about 7 at% without any failure in the centre of a KNK carrier element at a maximum linear rating of 800 W/cm. After dismantling in the hot cells of KfK, nondestructive examinations were carried out comprising dimensional controls, radiography, gamma-scanning and eddy-current testing. The results indicate differences in fuel behaviour with respect to composition of the fuel.
