Tank S-102 waste retrieval leak detection & monitoring & mitigation strategy

This paper presents a proactive and mitigative strategy for the identification and management of potential S-102 waste leaks during the S-102 Waste Retrieval and the basis for this approach. The strategy is based on preventing leakage, minimizing leak volumes if a lead should occur, and providing the best available leak detection and monitoring technologies. Ex-tank leak detection will use the baseline borehole gamma and neutron drywell logging trucks, supplemented with manually deployed neutron moisture measurements. Waste mitigation includes management of the retrieval fluids in a manner that limits the risk for a potential leak.
