1 Overview of Spent Fuel Management Programs Presented to: INMM 33 rd Spent Fuel Management Seminar, Alexandria, VA Presented By: Nigel Mote, Executive Director January 23, 2018 Note: The views expressed do not represent those of the or the United States federal government 1

2 About the Board The U.S. Nuclear Waste Technical Review Board (Board) was established by Congress as an independent federal agency in the 1987 amendments to the Nuclear Waste Policy Act (NWPA). 2

3 About the Board The Board evaluates the technical and scientific validity of U.S. Department of Energy (DOE) activities related to implementing the NWPA, wherever in DOE the activities are undertaken DOE activities include: Packaging of spent nuclear fuel (SNF) and high-level radioactive waste (HLW) and transportation of the wastes to a storage or disposal facility Site characterization, design, and development of facilities for disposing of SNF or HLW 3

4 About the Board Eleven members Candidates nominated by National Academy of Sciences solely on the basis of eminence and expertise Appointed by the President Serve part time for four-year, staggered terms May serve until replaced Supported by permanent, full time staff 4

5 About the Board Required to report its findings, conclusions, and recommendations to the U.S. Congress and the Secretary of Energy By law, has access to draft DOE documents allows Board recommendations to be made during decision-making, not after the fact Provides congressional testimony at the invitation of Congress 5

6 About the Board Holds public meetings each year in different locations in the United States Meetings are (now) webcast Provides technical and scientific comments in letters to DOE following public meetings Makes all official documents (reports, correspondence, meeting transcripts and materials, congressional testimony, etc.) available on its website: 6

8 Board Meetings in 2017 and 2018 Summer Meeting June 21, 2017 Location: Richland, WA Topic: Corrosion of High-Level Radioactive Waste Borosilicate Glass Spring Meeting March 27, 2018 Location: Washington, DC Topic: Operational and Performance Confirmation Monitoring and Retrievability of Emplaced HLW and SNF Summer Meeting June 13, 2018 Location: Idaho Falls, ID Topic: Technical Issues Related to Developing a Nationwide Effort to Transport SNF and HLW 8

9 Recent Board Reports Technical Evaluation of the U.S. Department of Energy Deep Borehole Disposal Research and Development Program January 2016 Survey of National Programs for Managing High-Level Radioactive Waste and Spent Nuclear Fuel: Update February 2016 Report to the U.S. Congress and the Secretary of Energy - Board Activities for the Period January 1, December 31, 2015 December 2016 Management and Disposal of U.S. Department of Energy Spent Nuclear Fuel December

10 Current Board Reviews Evaluation of DOE s Research Program to Determine the Potential Degradation of Commercial High-Burnup Spent Nuclear Fuel during Extended Storage and Transportation Impacts of Dry-Storage Canister Size on Storage, Transportation, and Disposal of Spent Nuclear Fuel Technical Issues Affecting Transportation Readiness Summary Report: Board Activities for the Period January 1, December 31, 2017 Corrosion of High-Level Radioactive Waste Borosilicate Glass Operational and Performance Confirmation Monitoring and Retrievability of Emplaced HLW and SNF 10

11 SNF Management Programs Country Spent Nuclear Fuel Storage Wet Dry Belgium At reactor At Doel bolted casks (TN- 24) Canada At reactor At reactors silos (Point Lepreau); MACSTOR vaults (Gentilly-2); casks (Pickering, Darlington, Bruce) Transport Disposal No repository program approved by government Five potential repository sites under consideration China Finland France At reactor At reprocessing facility At reactor At CISF At reactor At reprocessing facility At Qinshan CANDU fuel in MACSTOR-400 CISF under consideration by EDF Germany At reactor At reactor At CISF (Gorleben, Ahaus, Lubmin) CASTOR casks Beishan site in Gansu Province selected for URL (crystalline) Repository under construction at Olkiluoto (crystalline) License application for repository construction at Bure (HLW/clay) anticipated in Unclear whether spent fuel will be included. In March 2017, a bill authorizing the search for a geologic repository was approved by the German Parliament and by the council of German federal state governments.

12 SNF Management Programs Country Spent Nuclear Fuel Storage Wet Dry Japan At reactor At reactor At CISF under development Rep. of Korea At reactor At Wolsong CANDU fuel in MACSTOR/KN-400 Transport Disposal Site-suitability criteria developed. Map of suitable areas released in Site-screening effort underway. Repository siting process under development Spain At reactor At reactor CISF under development at Villar de Cañas Sweden At reactor At CISF Switzerland United Kingdom except Scotland United States At reactor Separate pool on reactor site At reactor At reprocessing site At reactor At former reprocessing site At reactor At CISF At reactor PWR (completed in 2016) At reactor mainly welded canisters CISF under consideration CISF Centralized Interim Storage Facility, welded casks No governmental decision to pursue repository disposal License application submitted for repository - Osthammar (crystalline) Three regions have been proposed for investigation (clay). Swiss govt. will decide by the end of 2018 how many of the three will be characterized. National Site Screening in progress Yucca Mountain (on hold) R&D programs related to other geologic environments 12
