HEAVY WATER MODERATED POWER REACTORS. Progress Report for January 1960
Approximately one-quarter of the construction and 85% of the firm design of the Heavy jWater Components Test Reactor (HWCTR) were complete at the end of January 1960. Safeguards analyses of the liquid-D/sub 2/O-cooled loop of the HWCTR showed that none of the accidents considered to date have serious potential. Exploratory tests of the a device for quenching the steam that would be generated in the boiling-D/sub 2/O- cooled loop of the HWCTR showed that a quencher could be designed to operat satisfactorily without excessive accompanying noise or vibration. Two Zircaloy-=cald tubes of crused, fused uranium oxide were cold swaged to a density of greater than 90% of theoretical. Several other cold-swagged oxide tubes clad with stainless steel were fabricated for irradiation specimens. Mechanical, hydraulic pressure, thermal-and pressure- cycling tests of tubular metallurgical joints between Zircaloy and stainless steel continued to show excellent properties.
