POWER REACTOR PROGRAM. Progress Report to E.I. du Pont de Nemours and Company for the Period April 1, 1959 through April 30, 1959

Technical Report ·
OSTI ID:4246864

The heat treatment of Zircaloy-2 clad power tubes in their copper extrusion Jackets is discussed. The extrusion of unalloyed U from six billets is described. The mechanics of beta treatment of extruded tubes in a vertical salt bath were worked out with the aid of a dummy Cu--10 wt.% Ni tube of power tube dimensions. Measurements on the prototype driver tubes indicate that dimensional tolerances can be met in the extruded condition. An attempt is being made to determine the cause of anomalous corrosion behavior of Zr--0.6 wt.%. Ni alloys arc melted from Zr sponge. A program is reported on-the preparation of slightly enriched U--2% Zr core, Zircaloy-clad tube for irradiation in the Vallecitos test reactor. (W.J.H.)
