Heavy Water Moderated Power Reactors Progress Report, April 1960

Description: Safeguards analyses of the isolated coolant Icops of the HWCTR indicated that accidental loss of ccoling water from the Icop heat exchangers will not lead tc vaper binding of the Icop D/sub 2/O pumps, or to other detrimertal consequences, providing that the reactor is scrammed following the loss of coolant. Several static seals of the types that will be used in the HWCTR exhinited leakage rates that were well below design specifications during cyclic tests at peak conditions of 1500 psi and 260… more

Heavy Water Moderated Power Reactors. Progress Report for December 1959

Description: At the end of 1959, 25% of the construction and 85% of the firm design of the Heavy Water Components Test Reactor (HWCTR) were complete. Further safeguards analyses of the HWCTR, done with the aid of analog and digital computers, corroberated earlier data which indicated that the reactor is highly self-regulating, and that the safety system should prevent release of radioactivity outside the containment building. Fabrication tests of metallic uranium fuels and preparation of irradiation specime… more

Heavy Water Moderated Power Reactors. Progress Report for February 1960

Description: At the end of February 1960, 30% of the construction of the Heavy Water Components Test Reactor (HWCTR) was compplete. Limits for safe operation of the reactor were defined, and the general procedures for startup, shutdown, and normal operation here formulated. A detailed analysis of operating stresses in the reactor vessel defined the ling that can be tolerated. Core swelling produced a maximum cladding strain of 0.7% in a Zircaloy-2-clad tube of U-2 wt.% Zr that was irradiated to an average b… more

Heavy Water Moderated Power Reactors. Progress Report for January 1960

Description: 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 sa… more

Heavy Water Moderated Power Reactors. Progress Report for March 1960

Description: Safeguards analyses of the boiling D/sub 2/O loop of the Heavy Water Components Test Reactor (HWCTR) show that neither a power failure nor a loss of cooling water will cause a serious accident if the reactor is scrammed. Construction was started on a full-scale mockup of the bayonet for this loop. The mockup will be used for studies of possible vibration phenomena associated with the flow of steamwater mixtures. Emphasis in the development of uranium metal fuel for power reactor use has been sh… more

Heavy Water Moderated Power Reactors Progress Report for May 1960

Description: BS>A Zircaloy-clad tube of unalloyed uranium that was irradiated in a loop of the NRU reactor to a maximum exposure of 950 Mwd/ton at a maximum uranium temperature of 40O deg C experienced less than 1.5% volume increase and 0.14% outer-cladding strain. Inspection of the swaged oxide tube that had failed during irradiation in a Savannah River reactor revealed that a 9-in.-long crack of as-yet-unknown origin had developed in the outer stainless-steel cladding of the tube. Transient calculations s… more

Heavy Water Moderated Power Reactors Progress Report for November 1959

Description: At the end of November, 20% of the construction and 80% of the firm design of the Heavy Water Components Test Reactor (HWCTR) were complete. Proof testing of various seals and mechanisms for the HWCTR continued satisfatorily. Further analyses are given of the transient behavior of the HWCTR isolated coolant loops and of the experimental data on the nuclear effects of hot moderator. The results of additional fabrication and irradiation tests of uranium metal and uranium oxide are recorded. The m… more

Heavy Water Moderated Power Reactors. Progress Report for October 1959

Description: Continued progress is reported on the design and construction of the Heavy Water Components Test Reactor; 78% of the firm design and 17% of the construction were complete at the end of October 1959. Approximateiy 15% of the firm design for the isolated coolant loops of the HWCTR was also complete. The results of further fabrication tests and irradiation tests of fuel tubes of natural uranium metal are reported. One of the metal tubes failed under irradiation, while other irradiations of metal f… more

Heavy Water Moderated Power Reactors. Progress Report, January-February 1964

Description: ABS>The HWCTR was operated most of January for irradiation tests of fuel assemblies. The reactor was shut down early in February for repair of a D/sub 2/ O leak in one of the steam generators. The D/sub 2/O loss during reactor operation in January averaged 14 pounds per day, which is equivalent to the annual loss of 7% of the inventory. An assembly of compacted UO/sub 2/ tubes was undamaged by irradiation to 10,000 Mwd/tonne in the HWCTR; the free-gas content of the tubes was somewhat lower … more

Heavy Water Moderated Power Reactors Progress Report, September 1961

Description: At the end of September l961, construction of the Heavy Water Components Test Reactor was about 90% complete. Thirty-two compacted tubes of crushed, fused uranium oxide in Zircaloy sheaths were fabricated for irradiation tests and destructive evaluation. lrradiation tests of the tubes were started in the Vallecitos Boiling Water Reactor and at Savannah River. The fabrication process for the tubes included steps designed to exclude hydrogenous material from the oxide cores, thereby eliminating t… more
