ELECTROLYTIC DISSOLUTION OF NUCLEAR FUELS. PART III. STAINLESS STEEL (304) IN NITRATE SOLUTIONS

Description: The potential-current density relationships for 304 stainless steel dissolution in a nitrate system were studied as a function of solution composition and temperature in order to optimize the conditions for electrolytic dissolution of ihis material. In the nitrate system, the anodic dissolution of steel takes place in the transpassive region. Under some conditions, deviations from Tafel behavior are observed which depend greatly on the nitrate and hydrogen ion concentration, and on temperature.… more

An Investigation of the Corrosion Resistance of Brazing Alloys for Austenitic Stainless Steel Fuel Elements for Service in 565 F Pressurized Water

Description: Since brazing was the method selected for joining the stainless steel SM- l reactor fuel element, corrosion studies were conducted on various potential brazing alloys to evaluate their resistance under the approximate pressurized- water conditions of the SM-1. The program consisted mainly of testing type 304L stainless steel T'' joints brazed with selected alloys in quiescent, degassed, and deionized autoclaved water at 565 deg F under 1200-psi pressure. In the initial phase of the investigatio… more

TRANSMISSION ELECTRON MICROSCOPY OF URANIUM

Description: A technique for the thinning of U for transmission electron microscopy is described. The main difficulty was the removal of the anodic film that formed during electropolishing. However, excellent electroplating results were obtained with a solution of 800 cc ethanol, 500 cc ethylene glycol, and 500 cc H/sub 3/PO/ sub 4/(85%) with the U cathode at 30 ma/cm/sup 2/ and room temperature. The anodic film that formed was then removed by electropolishing in a solution composed of 75 cc H/sub 2/SO/sub … more

RECOVERY OF U FROM PYROLYTIC CARBON-COATED UC$sub 2$ SPHEROIDS

Description: 100% recovery of uranium from pyrolytic carboncoated spheroids of uranium dicarbide was accomplished by an aqueous electrolytic process at the small scale laboratory level. This result was obtained in a system which circulated 1 molar nitric acid through a thin bed of the spheres. The bed was supported between a glass frit and the anode, with which the bed was in contact. The anode was a spiral of platinum wire; the cathode was a grid of tantalum wire. Current density was about 0.2 the average … more
