Dr. Christine Langton

2016 Fred C. Davison Distinguished Scientist Award

Citizens for Nuclear Technology Awareness is pleased to announce that the winner of the 2016 Fred C. Davison Distinguished Scientist Award is Dr. Christine Langton of the Savannah River National Laboratory (SRNL). She has more than 33 years of experience and a long history of making significant contriubutions to the Department of Energy (DOE) waste management, tank closure, and reactor decomissioning program, and has brought national-level and international recognition to the SRNL.

Dr. Langton is nationally and internationally recognized as an expert in designing innovative materials and processes for treating low-temperature radioactive waste and for designing and implementing specialty grouts and concretes for high-level waste tank closure and D&D projects. She has provided solutions to legacy waste management problems at the Savannah River Site (SRS) and numerous other DOE sites. Her contributions range from experimental results that further the mechanistic understanding of material performance under realistic exposure conditions to field implementation strategies and planning.

Dr. Langton's expertise as a consultant is sought after throughout the DOE Complex and internationally including Japan, Australia, Canada, China, and Brazil. One example of that international recognition is her role as the principal investigator for a Strategic Partnerships Program that was finalized in 2013 between Tokyo Electric Power Company, Japan and the SRNL to provide assistance with recovery efforts from the Fukushima Daiichi disaster. In her role as principal investigator she prepared a feasibility study on leak-sealing technologies, reviews test plans, and serves as a consultant on the use of cement to seal leaks. She has also received recognition for participation in the International Atomic Energy Agency missions on radioactive waste treatment, next generation fuel cycle waste management, low- and intermediate-level waste conditioning for final disposal, and technology for waste treatment training for China.

From 2004-2005, Dr. Langton stepped out of her role as an SRNL researcher and took a position with Washington Group - Black and Veatch, LLC as an expert and manager for several reconstruction projects in Iraq that took advantage of her cementitious-materials expertise.

Dr. Langton's recent interest is reducing the nuclear danger associated with the nuclear waste inventory in nuclearized and non-nuclearized countries with small amounts of radioactive waste and no or limited radioactive waste disposal capabilities. To this end, she and an SRNL team are supporting efforts in Brazil for borehole disposal of sealed sources.

Dr. Langton's work has resulted in significant risk reduction of the contaminated legacy not only at the SRS and other DOE Complex sites, but also across the globe. Using innovative approaches to cementitious materials formulation and deployments, she has provided key concepts and technologies that have allowed the risk reduction to proceed at a more cost-effective and efficient mannter that benefits not only the DOE, but also the nearby communities.
