AbstractHigh-field magnetization measurements at 4.2 K on several U2T2 x (T = Ni, Rh, Pd, Pt; X = In, Sn) compounds have been performed on free and fixed powders up to 57 T. An antiferromagnetic ground state of U2Ni2Sn is corroborated by metamagnetic transitions at 30, 39 and 51 T. U2RhzSn shows one metamagnetic transition at 21 T and U2Pd2Sn two metamagnetic transitions at 39 and 45 T. U2Pt2In shows no metamagnetism up to 57 T which is in agreement with the non-magnetic ground state of this compound. The short-pulsed measurements up to 57 T are compared with previous results obtained in quasi-static fields up to 35 T.

Japan Atomic Energy Agency has developed vibro-packed fuel as one of the candidates for commercial fast breeder reactor fuels. In this study, vibro-packing experiments were carried out to investigate particle movement during vibro-packing as well as particle distribution after the completion of vibro-packing. Non-spherical uranium dioxide particles and spherical metallic uranium particles were used to simulate mixed oxide particles and oxygen getter particles, respectively. These experiments revealed the following facts. It is important to prevent segregation by means of feeding each size of the fuel particles uniformly into a cladding tube in order to disperse oxygen getter particles uniformly. ''Simultaneous feeding'' with volumetric powder feeders is useful to realize the above.
