Tank 241-T-110 tank characterization plan

This Tank Characterization Plan (ICP) identifies the information needed to address issues related to short-term and long-term safe storage and long-term management of single shell tank 241-T-1,10 (T- 110). It should be understood that needs and issues surrounding tank T-110 are evolving as new information becomes available. As a result, this TCP addresses only issues that have been identified to date. It is expected that changes may be necessary as additional issues or needs arise which impact the management of tank T-110. As necessary, this TCP will be revised to reflect changes. This plan reflects the best information available as of August 1996. Tank T-110 entered into service in the first quarter of 1945. The tank began receiving second- cycle decontamination waste in the first quarter of 1945 (Agnew et al. 1995). The tank began to cascade overflow to Tank 241-T-111 in October 1945. In the second quarter of 1952, the tank began receiving 224 waste in addition to the second-cycle waste. The tank contained second-cycle and 224 waste until the first quarter of 1976. During the third quarter of 1974, the tank received waste water. The tank was removed from service in 1976. A level adjustment was made in April of 1982. The tank was primarily stabilized in 1978 and partially isolated in December 1982. The tank is classified as a sound, non-stabilized tank (Brevick et al. 1995). Tank T-110 currently contains a total volume of 14351789 kL. (379 kgal ) of waste, which is equivalent to 338.5 cm (133 in) of waste as measured from the baseline of the tank (Hanlon 1996). Tank T-110 is on the Flammable Gas Watch List. Near-term sampling and analysis activities are focused on verifying or changing the Watch List tank status, and identifying any new safety issues. If new safety issues are identified, analysis activities consistent with the identified issue will be performed. In addition to resolving safety issues, it is intended that all tank waste will be subject to pretreatment and retrieval to prepare it for final storage or disposal. Presently, these long-range plans are not yet fully identified and, therefore, are not included in this document
