Hood, R R; Isakoff, L comps

At the end of October l961, construction of the Heavy Water Components Test Reactor (HWCTR) was nearly complete, and prestartup operations were begun. A tentative schedule was prepared for irradiation of various test fuel elements in the HWCTR. Six Zircaloy-clad tubes of compacted uranium oxide were irradiated uneventfully to modest exposure in a Savannah River reactor, and are awaiting destructive examination. Buckling measurements were made on six lattices of natural UO/sub 2/ rod clusters in D/sub 2/O. In a heat transfer test at Columbia University, burnout was reached in an electrically heated bundle of nineteen rods at a maximum heat flux of 330,000 pcu/(hr)(ft/sup 2/) when the exit steam quality of the boiling water coolant was 56%.
