Jul 02, 2018One of the tanks identified as at high risk for corrosion, Tank AZ-101, holds waste that is expected to be treated as high-level radioactive waste, according to Ecology officials. The waste is expected to remain in the tank until 2036, when the vit plant is (plate) Standard Guide for Sampling Radioactive Tank Waste(steel) 4.2 Many high-level wastes have been treated to remove strontium (Sr) or cesium (Cs), or both, have undergone liquid volume reductions through pumping and forced evaporation or have been pH modified, or both, to decrease corrosion of the tanks. These processes, as well as waste streams added from multiple process plant operations, often resulted in precipitation, and produced multiphase wastes corrosion of steel tanks in liquid nuclear wastes(plate) THE SENSITIVITY OF CARBON STEELS' SUSCEPTIBILITY TO corrosion of steel tanks in liquid nuclear wastes(steel) The Hanford tank reservation contains approximately 50 million gallons of liquid legacy radioactive waste from cold war weapons production, which is stored in 177 underground storage tanks.

The Management of High-Level Radioactive Wastes

Management of a tank farm for liquid radioactive wastes requires careful planning several years ahead. The technology for safe storage of high-level liquid waste in tanks over periods of many years have been demonstrated in several countries. Some leakage has occurred from tanks in the USA. This, however, was from mild steel tanks of early design.(plate)Corrosion of Steel Tanks in Liquid Nuclear Wastes corrosion of steel tanks in liquid nuclear wastes(steel) Very low general corrosion rates (< 10 m. yr -1) were estimated using EIS measurements, indicating that general corrosion rate of the steel in contact with liquid wastes would not be a cause of corrosion of steel tanks in liquid nuclear wastes
