Tank 241-C-106 is a single shell tank at the Hanford Site in south central Washington State, and is the only tank on Hanford`s High-Heat Tank Watch List. This action plan defines possible abnormal conditions (such as ventilation system failure or a leaking tank) that could lead to excessive temperature increases in tank 241-C-106, and documents pre-planned contingency actions would effectively mitigate the consequences of such increased temperatures. Potential structural damage may result from high temperatures caused by inadequate cooling. Tank 241-C-106 contains a significant amount of high-heat radioactive waste, mainly strontium, and requires forced ventilation combined with evaporation for adequate cooling. Forced ventilation at 2,400 ft/min, along with periodic water additions of approximately 6,000 gal/month, is currently maintaining the tank temperature within the required range. This action plan addresses high-heat concerns and corrective measures unique to tank 241-C-106 and to proposed sluicing activities in tank 241-C-106. Other general emergency actions for the 200 Area Tank Farms, such as those forest fires and earthquakes, are described in WHC-CM-4-43, `Emergency Management Procedures` and are not included in this document.
