Available in PDF, EPUB and Kindle. Book excerpt: Radioactive liquid wastes are produced as a consequence of processing fuel from Savannah River Plant (SRP) production reactors. These wastes are stored in mild steel waste tanks, some of which have developed cracks from stress corrosion. A laboratory test was developed to determine the relative agressiveness of the wastes for stress corrosion cracking of mild steel. Tensile samples were strained to fracture in synthetic waste solutions in an electrochemical cell with the sample as the anode. Crack initiation is expected if total elongation of the steel in the test is less than its uniform elongation in air. Cracking would be anticipated in a plant waste tank if solution conditions were equivalent to test conditions that cause a total elongation that is less than uniform elongation. The electrochemical tensile tests showed that the supernates in salt receiver tanks at SRP have the least aggressive compositions, and wastes newly generated during fuel repocessing have the most aggressive ones. Test data also verified that ASTM A 516-70 steel used in the fabrication of the later design waste tanks is less susceptible to cracking than the ASTM A 285-B steel used in earlier designs.

Book excerpt: A laboratory test was developed to determine the relative aggressiveness of nuclear process waste on mild steel. Tensile samples were strained to fracture in synthetic waste solutions in an electrochemical cell with the sample as the anode. When total elongation in the test is less than the uniform elongation observed in air, stress, corrosion cracking is likely if the steel is exposed to equivalent solutions and temperatures in service. A response surface equation was derived that relates elongation of a mild steel (ASTM A 285-B) to the combined effect of four independent variables of the waste solution: temperature, NO3−, NO2−, and OH−. Elongation in the electrochemical tensile test, as a measure of stress corrosion cracking potential, can be predicted from the actual waste compositions to within an average of 8 percent of the measured values. The electrochemical tensile tests showed that the supernates in SRP salt receiver tanks are the least aggressive compositions, and wastes newly generated by the separations process are the most aggressive ones. Test data also verified that ASTM A 516-70 steel is superior to ASTM A 285-B. To decrease the possibility of stress corrosion cracking, limits were recommended for waste compositions, based on present results wedge-opening-loaded test results, and expected plant operating conditions. 12 fig.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hanford reservation Tank Farms in Washington State has 177 underground storage tanks that contain approximately 50 million gallons of liquid legacy radioactive waste from cold war plutonium production. These tanks will continue to store waste until it is treated and disposed. These nuclear wastes were converted to highly alkaline pH wastes to protect the carbon steel storage tanks from corrosion. However, the carbon steel is still susceptible to localized corrosion and stress corrosion cracking. The waste chemistry varies from tank to tank, and contains various combinations of hydroxide, nitrate, nitrite, chloride, carbonate, aluminate and other species. The effect of each of these species and any synergistic effects on localized corrosion and stress corrosion cracking of carbon steel have been investigated with electrochemical polarization, slow strain rate, and crack growth rate testing. The effect of solution chemistry, pH, temperature and applied potential are all considered and their role in the corrosion behavior will be discussed.
