Description: The development of dimensionally stable alloys for high temperature reactor application is discussed. Cold pressing followed by sintering was determined to be the most satisfactory method. Evaluation of alloys by alpha - beta thermal cycling indicated the superiority of U--Mo and U--Nb alloys. A few specimens containing small additions of Mo, Nb, and Si were irradiation tssted in the Materials Testing Reactor. Of these, the Nb alloy (1.6 wt.% Nb) appeared to be most stable. The Mo alloys were somewhat less satisfactory and the alloys containing Si were not stable. (auth)
