Pre-startup operation of the Heavy Water Components Test Reactor (HWCTR) continued throughout November 1961. Hydraulic testing of the main D/sub 2/O system of the reactor was progressing satisfactorily with light water. A resume is presented of experimental data obtained at the Savannah River Laboratory on the bucklings of natural uranium oxide rods in heavy water. The thermal neutron diffusion coefficient for heavy water was measured as a function of temperature from 20 to 220 deg C. The measurements agreed with theoretical predictions. At the end of the month, fabrication of 15 sets of thin-walled tubes of uranium metal for irradiation tests in the HWCTR was 85% complete. Further experimental data are reported on heat transfer limits for a single rod cooled by forced flow of boiling water at 1000 psia. (auth)
