POWER REACTOR PROGRAM PROGRESS REPORT TO E. I. du PONT de NEMOURS AND COMPANY FOR THE PERIOD AUGUST 1, 1960 THROUGH AUGUST 31, 1960
The core design for a demonstration set of outer tubes includes the rear end shape and thickened inner sleeve of tube 88 and a slight modification of the front end shape used for tube 99. Three prototype inner tubes were extruded. Work to determine cooling rates in BETA treatment was initiated and results were obtained for innner toinwalled tubes. outer thin-walled tubes, and thick- walled tubes. Processing two unenriched VBffl tubes with uranium--1.5 wt.% molybdenum cores was held up while optimum conditions of heat treatment are established. A prototype enriched. unalloyed uranium VBWR tube was extruded. A uranium --1 wt.% silicon billet core was cast and epsilorized for fabrication of additional specimens for capsule irradiation. The experimental work to determine tensile. stress-rupture. and creep properties of unalloyed dingot uranium and urarium --1.5 wt.% molybdenum was completed. Three additional stainless steel -- Zircaloy joints were extruded but not evaluated. (For preceding period see NMI- 7230.) (W. L.H.)
