Panel Session 83: Development of the DOE Mercury Management Strategy
This panel discussion addressed the current efforts to develop an integrated strategy for managing the mercury (Hg) challenges across the DOE complex, including challenges in remediation of Hg contamination and related ongoing or planned technology development efforts across the EM complex. Panel members discussed opportunities for collaboration in defining and implementing a mercury management strategy for the various sites, national laboratories, and contractors and for all to provide technical information for DOE to develop an integrated, cost effective Hg management strategy. Emphasis of the panel was placed on challenges at the Oak Ridge Reservation and the Savannah River Site. Opening remarks were made by Ming Zhu. Ming stated that the Academy of Sciences recently released a report on the challenges of addressing Hg in the environment; the report leveraged recent remedial efforts. Presentations proposed include: 1 - Approach to Addressing Mercury at Y-12 (Brian Henry, US DOE OREM (USA)); 2 - Mercury Management Strategy (Renee Echols, FireWater Associates, LLC (USA)); 3 - Integration of Science to Address Mercury Clean-up Challenge (Eric Pierce, Oak Ridge National Laboratory (USA)); 4 - Mercury Related Research and Development by CRESP (Kevin Brown, Vanderbilt University - CRESP (USA)); 5 - Lessons Learned from D and D of West COLEX (Kent Fortenberry, UCOR (USA)); 6 - Mercury in the SRS Liquid Waste System (Richard Edwards, Savannah River Remediation (USA)); 7 - TDD Program on Mercury at Savannah River (Bill Wilmarth, Savannah River National Laboratory (USA))

Long-Term Management of Mercury at the Savannah River Site Liquid Waste System - 17364
Mercury in the Savannah River Site Liquid Waste System (LWS) originated from decades of canyon processing where it was used as a catalyst for dissolving the aluminum cladding of reactor fuel. Approximately 60 metric tons of mercury (Hg) is currently present throughout the LWS. Mercury has long been a consideration in the LWS, from both hazard and processing perspectives. In February 2015, a Mercury Program Team (MPT) was established at the request of the Department of Energy to 'take an integrated, system-wide approach to evaluating the movement, monitoring, and collection of mercury through the entire Liquid Waste System/Facilities.... The key objective of the Mercury Program Team was to evaluate mercury in the LWS and develop a comprehensive action plan for long term management and removal of mercury. After completion of Phase I and II, a comprehensive action plan for long-term management and removal of mercury was developed and recommendations for actions are categorized under three broad categories - Plant Operations, Technology Development, and Sampling and Monitoring. The resolution of these Action Items will provide long term management and removal of mercury through the LWS. (authors)

Electroform Welding
Electroform welding used to join variety of parts without addition of detrimental heat. Technique developed so large and/or complexly shaped parts joined without degrading properties of materials. Commercial uses include joining dissimilar alloys. Beneficial for suppression of distortion or maintenance of close tolerances in precise components.
