Johnson, G D

The Waste Tank Flammable Gas Stabilization Program was established in 1990 to provide for resolution of a major safety issue identified for 23 of the high-level waste tanks at the Hanford Site. This safety issue involves flammable gas mixtures, consisting mainly of hydrogen, nitrous oxide, and that are generated and periodically released in concentrations that nitrogen, exceed the lower flamability limit. Initial activities of the program have been directed at tank 241-SY-101 because it exhibits the largest risk. Activities conducted in fiscal year (FY) 1991 included waste sampling, waste sample analysis, development of tank models, conducting laboratory tests with synthetic wastes, upgrading of tank instrumentation and ventilation systems, evaluation of new methods for characterizing waste, and development of remedial actions. In addition to the work being conducted to resolve the flammable gas issue, programs have been established (Gasper and Reep 1992) to develop corrective actions for high priority safety issues associated with potential explosive mixtures of ferrocyanides in tanks, potential organic-nitrate reactions in tanks, and for the continued cooling for heat generation in tank 106{degrees}C. The purpose of this document is to provide a brief description of the FY 1992 priorities, logic, work breakdown structure (WBS), and task descriptions for the Waste Tank Flammable Gas Stabilization Program.
