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)

Technetium Management Program Plan - 17376
Technetium management is a high-priority activity for the U.S. Department of Energy (DOE) Office of Environmental Management (EM) complex. Waste management and remediation issues involving technetium represent environmental risks and challenges that are unique to DOE. This plan lays out the technology development activities that are underway as well as future technology needs to address technetium issues across DOE EM sites and across programmatic areas of tank waste, groundwater and soils, and facility decommissioning and deactivation in order to be comprehensive and to allow integration of similar activities. The program was developed in close coordination with site representatives and program offices. Activities and needs that were identified share common themes and were grouped into areas of characterization, treatment, and disposition. Characterization includes understanding the inventory at particular locations, the chemical species, and chemical and physical behavior, whether in a treatment process flowsheet or a geological setting that displays periodic contaminant releases. The tools for characterization in these different environments might use the same sensors or protocols. Treatment options include methods to capture technetium such as ion-exchange or manipulation of oxidation states, which also may be applied across program areas. Disposition includes end-points of the processes and environmental risk, including waste form behavior, mobility of technetium once it is treated or remediated, and long-term monitoring. Disposition represents integration of all cleanup actions at a site. (authors)
