Various operations are authorized in Hanford single-shell and double-shell tanks that disturb all or a large fraction of the waste. These globally waste-disturbing activities have the potential to release a significant volume of retained gas. Analyses are presented for expected gas release mechanisms and the potential release rates and volumes resulting from these activities. Recommendations for gas monitoring and assessment of the potential for changes in tank classification and steady-state flammability are also given.
