High heat generation safety issue in tank 241-C-106

摘要

A 'White' paper was written on the High Heat Generation Safety Issue in Tank 241-C-106. The issue is if tank 241-C-106 should start leaking, the lack of alternative cooling methods will require continued addition of water and thereby possibly increase the amount of leakage to the ground. If the current methods of cooling the tank are stopped, the sludge and concrete structure will heat to temperatures greater than established limits and may cause structural damage, leading to dome collapse and possibly an unacceptable radioactive release to the environment. Potential approaches to the resolution of this issue were evaluated, and waste retrieval by sluicing and transfer to a double- shell tank was selected. The paper gives background information on the tank and an assessment of the issue and its resolution, with references to support the paper.
