Title: HEAVY WATER MODERATED POWER REACTORS. Progress Report for June 1960

Abstract

At the end of June 1960, 36% of the construction and 94% of the firm design of the Heavy Water Components Test Reactor (HWCTR) were complete. Revised calculations of transients in the liquid-D/sub 2/O-cooled loop of the HWCTR showed that the safety of the loop was not impaired by recent changes in the location and design of the loop heat exchanger. Preliminary operation of a full- scale mock-up of the bayonet for the boiling-D/sub 2/O-cooled loop of the HWCTR indicated that flow-induced vibrations probably will not be a serious problem in this loop. Irradiation specimens were prepared of Zircaloy-clad tubes of uranium oxide that had been vibratory-compacted and swaged to 91% of theoretical density. The National Research University irradiation of a Zircaloy-clad uranium metal fuel tube was terminated because of mechanical damage to the assembly during an attempted reinsertion into the reactor loop. Tandemextruded joints of Zircaloy to stainless steel were readied for long-term irradiation tests to determine the effects of exposure on the mechanical properties of the joints.
