Title: HEAVY WATER MODERATED POWER REACTORS. Progress Report, January-February 1964

Abstract

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 than expected. Two Zircaloy-clad tubes of unalloyed uranium exhibited large local decreases in outer diameter during irradiation to 7,000 Mwd/tonne. Experimental data were obtained on heat-flux limits for water flow in tubular channels at 750 to 1500 psia. Burnout measurements were made on single tabes and on three tubes connected in parallel to a common coolant supply. (auth) O H15521 The interest in fast reactors is indicated; and the design, construction, operation, experimental program, and performance of the Dounreay fast reactor are summarized. (D.C.W.)
