1 National Laboratory Engagement in Japan: From Clean-up to Decommissioning Jeff Griffin, Ph. D. Associate Laboratory Director Environmental Stewardship Directorate Savannah River National Laboratory Waste Management Symposia 2016 Session 91 March 9, 2016 SRNL-MS

2 Unique Set of Attributes Enable Assistance to Japan in Recovery 60 years experience developing, testing, and deploying remediation options in a natural environment similar to that in and around Fukushima Knowledge and experience regarding contamination by and migration of cesium, the chief radioisotope of concern around Fukushima Focus on field-deployable solutions ( We put science to work ) to match the urgency of the Japan situation Satellite photo of SRS overlaid with Cesium-137 distribution Experience in working successfully with stakeholders-- communities, regulators, special interest groups--to build support for remediation options Participation in Japan recovery efforts from the immediate aftermath of the Daiichi NPS accident to the present Unit 2 containment Experience at Chernobyl and Three Mile Island Three Mile Island Nuclear Generating Station 2

3 SRNL Interactions with Japan on Fukushima Response/Recovery US Embassy Science Fellow - worked with Ministry of Environment Decontamination Team to provide expertise and experience in decontamination for offsite areas o Bob Sindelar, SRNL o Mark Triplett, PNNL o Sang-Don Lee, U.S. EPA International Expert Panel Support to IRID/MRI proposal and project reviews related to contaminated water at the Fukushima Daiichi NPS o Contaminated groundwater counter-measures o Detritiation technologies review Japan Atomic Energy Agency (JAEA) o Senior advisory roles in-country for Collaborative Laboratories for Advanced Decommissioning Science (CLADS) o Advice on analytical methods and bases for laboratory information and design Fukushima Nuclear Power Station Tank Farms Environmental Radiochemistry : Rapid Methods For Sr-89/90, Actinides Nuclear Damage Compensation and Decommissioning Facilitation Corporation (NDF) o Discussions on waste management planning and support and analytical laboratory operation 3

4 National Laboratory and TEPCO Collaboration In January 2012, Deputy Secretary of Energy Daniel Ponemon recommended TEPCO seek assistance from SRNL and PNNL In September 2012, entered initial Work-for- Others with TEPCO to described US national laboratory experience and expertise that could support TEPCO at Fukushima In September 2013, TEPCO signed an Umbrella Work-for-Others contract with SRNL and PNNL for additional activities o Establishes task approval and management system Project Task Statements o o Allows multi-party approval Provides gateway to broader National Laboratory system TEPCO s first visit to SRNL in February 2012 SRNL management re-visiting Fukushima Daiichi NPS in November

5 New TEPCO Collaborations Area 100. GROUNDWATER MANAGEMENT Collaboration on development of comprehensive monitoring plan Continued to advise on frozen barrier implementation Area 200. GROUTING-RELATED TECHNIQUES Examination of radiolysis and degradation of grout and polymer leak-seal materials Examination of methods for monitoring performance of cured grout Identification and assessment of leak detection sensors/ methods and robotic deployment methods for sensor platform Layout Plan for Land-side Impermeable Wall (Frozen Soil Barrier Area 400. WASTE TREATMENT/DISPOSAL Sampling and analysis for characterization and management of ALPS secondary waste Reactor Specialized Grout Pour TEPCO Analytical Laboratory Benchmarking initiative at SRNL and INL February

6 Looking Forward - Support to Strategic Planning Efforts Involvement in strategic planning and options evaluation for critical phases of clean-up work at Fukushima and surrounding areas Laboratory Frameworks in Strategic Planning Spatial Approach o Provide technical collaboration on road-mapping efforts and remediation options analysis o Multiple resources and reach-back available o Perform technology evaluation and validation o Support stakeholder discussions on technology deployment Mutual Benefit o Improved understanding of issues and relationship building Early identification of technical support available at U.S. labs More rapid laboratory engagement at task level Devise strategies to mitigate and address emerging issues and problems o Support technology maturation strategies for longerterm planning Hydrological Other Site Specific Conceptual Model and Optimized Strategy Geochemical key inter-relationships that bridge these topics Temporal 6

7 Summary US National Laboratory experience and capabilities enable the US to assist Japan in recovery from the nuclear disaster at Fukushima both onsite and offsite. Traditional US National Laboratory roles have broad applicability. Innovative technologies - development and maturation through deployment Technology assessments Analysis of strategies and technology options Stakeholder engagement and assurance Japan s exceptional efforts in response, clean-up and recovery can provide valuable experience and lessons learned for the US Environmental Management clean-up mission. 7
