This report provides technical information on the status of an ongoing evaluation of underground waste tanks for continued storage of radioactive waste at the Hanford Site. The initial status report was issued in September 1978, followed by an update in October 1980. The data are generic to all of the underground, reinforced-concrete waste storage tanks at Hanford and include study results, evaluation methods, and recommended future work related to long-term disposal. Though elevated temperatures continue to be a dominant factor affecting concrete strength, the initial condition of the concrete appears to be most important in determining the present or future condition of the concrete. This document provides a summary of work completed in the past two years. This includes: (1) results of laboratory tests to determine concrete durability when exposed to various waste forms for use in establishing a technical data base for assessment studies; (2) properties of concrete removed from the haunch and wall of a single-shell tank; (3) computer analyses determining tank sensitivity to various loads; and (4) thermal heat transfer analyses of long-term disposal options. 35 figures, 16 tables.
