HEAVY WATER MODERATED POWER REACTORS. Progress Report for May and June 1959
Continued progress is reported on the design and construction of the Heavy Water Components Test Reactor (HWCTR), a high-temperature facility for simultaneously irradiating sizable numbers of fuel elements under power reactor conditions. In particular, the design of the normal and emergency power supply is reviewed, experimental verification of the adequacy of the control and safety rod system is given, and the fabrication of fuel tubes for the unit is discussed Progress is also reported on several general studies of importance to the technology of heavywater-moderated, natural-uranium-fueled power reactors. Preliminary experimental confirraation was obtained of the methods used for predicting the nuclear properties of fuel lattices that are moderated with hot heavy water. Further tests are described for the fabrication of fuel tubes of uranium metal and uradium oxide. Encouraging results continue from the irradiation test of a prototype metal fuel tube in the Vallecitos Boiling Water Reactor. The initial results of high-temperature irradiation tests on uranium metal slugs also appear satisfactory. Tests of stainless steel specimens show that a significant relaxation of stresses occurs during irradiation (For preceding pericd see DP-385.) (auth)
