The U.S. Nuclear Waste Technical Review Board (Board)1 held its 2018 Spring Meeting in Washington, D.C., on March 27, 2018, to review information from several international repository programs related to (i) operational and performance confirmation monitoring of a geologic repository for high-level radioactive waste (HLW) and spent nuclear fuel (SNF) and (ii) retrievability of emplaced HLW and SNF. This report presents a summary of the meeting and the Board’s observations related to repository monitoring and retrievability of emplaced HLW and SNF.
This report is based on the Board’s review of the U.S. Department of Energy’s (DOE) efforts to manage the spent nuclear fuel (SNF) under its control at four federal facilities.
The Report summarizes Board activities, conclusions, and recommendations from January 1, 2013, through December 31, 2015. During the period, the Board focused on activities undertaken by the U.S. Department of Energy (DOE) related to the packaging, transportation, and disposal of spent nuclear fuel and high-level radioactive waste.
This 2016 report is a revision of the survey report issued by the Board in 2009. It describes 30 technical and institutional attributes of nuclear waste programs in 13 countries.
The U.S. Nuclear Waste Technical Review Board (Board) held the International Technical Workshop on Deep Borehole Disposal of Radioactive Waste in Washington, D.C., on October 20 and 21, 2015, to review the technical and scientific validity of U.S. Department of Energy (DOE) activities related to assessing the feasibility of using deep boreholes to dispose of some radioactive waste. The Board prepared this report based on its review of DOE reports and presentations at the workshop, as well as on the presentations by and discussions among experts from the U.S. and other countries.
The basis of this report relies on a comparative historical inquiry into two dozen siting efforts that have taken place over the past half century in ten different nations. This version, an overview and summary, is a short synopsis of the major insights that derive from that study.
This report is based on the Board’s review of U.S. Department of Energy (DOE) reports and studies supporting a new DOE initiative involving the development of two mined geologic repositories: one to dispose of defense high-level radioactive waste (HLW) and possibly some DOE-managed spent nuclear fuel (SNF), and another to dispose of commercially generated HLW and SNF, together with other DOE-managed HLW and SNF.
This report documents the U.S. Nuclear Waste Technical Review Board's activities, findings, and recommendations for the period covering January 2008 through December 2012.
In August 2013, the Board submitted this Report, Review of U.S. Department of Energy’s Activities to Preserve Records Created by the Yucca Mountain Repository Project, on the Board’s evaluation of Department of Energy (DOE) activities related to archiving and preserving materials developed over almost 30 years by the Yucca Mountain repository project.
The purpose of this report is to extract knowledge while it is still available from experiences to date of the Yucca Mountain deep geologic repository program and other management programs for high-activity waste. In this report, the Board examines from a technical perspective the history of the Yucca Mountain program and some other nuclear waste programs and discusses technical information and insights that may be useful for future U.S. high-activity waste management and disposal efforts.
This report describes work being performed by the Board to evaluate the effects on the management of spent nuclear fuel and high-level radioactive waste of various fuel-cycle options being considered by the U.S. Department of Energy (DOE). Of particular interest to the Board are the types and quantities of the radioactive waste streams that would be generated. The Board has developed a computer-based systems analysis tool (NUWASTE) to support its technical evaluation of DOE activities in this area. Included in the report are initial findings from NUWASTE analyses.
This report explores the efforts of 13 nations to find a permanent solution for isolating high-level radioactive waste and spent nuclear fuel generated within their borders. It builds on information in the Board's 2009 Survey of National Programs for Managing High-Level Radioactive Waste and Spent Nuclear Fuel. Unlike the earlier document, however, this report describes the programs and their histories and discusses inferences that can be drawn from their experiences.
This report reviews available public literature on storage and handling of used nuclear fuel related to the safety of extended-term dry storage and subsequent transportation of U.S. commercial used nuclear fuel after long storage periods.
This report describes 30 technical and institutional attributes of nuclear waste programs in 13 countries. It does not make judgments, rather the report provides factual information for the U.S. Congress and the Secretary of Energy that can be used for evaluating waste management options.
This letter report updates the U.S. Congress and the Secretary of Energy on the U.S. Nuclear Waste Technical Review Board’s mission, continuing role, and refocused goals as the U.S. approach to managing spent nuclear fuel and high-level radioactive waste is evolving.
Between March 1, 2006, and December 31, 2007, the period covered by this report, the Board focused its evaluation on five critical technical issues dealing with pre-closure operations of the waste management system and on six critical technical issues dealing with post-closure performance of the proposed Yucca Mountain repository. The Board also explored in depth the crosscutting issue of thermal management. The Board’s views on these issues are explained in greater detail in the body of this report.
In this report, the U.S. Nuclear Waste Technical Review Board presents its evaluation of revised DOE estimates of water infiltration at Yucca Mountain. The infiltration estimates were revised because violations of quality assurance procedures were alleged to have been committed by U.S. Geological Survey employees involved in gathering and analyzing infiltration data at Yucca Mountain in the 1990's.
This report, which is the Board's second report of 2006, contains summaries of Board findings and recommendations contained in the following: letters to the Director of the Office of Civilian Radioactive Waste Management (OCRWM) following Board meetings held in February, May, and September 2006, a letter and enclosures sent to the Director of OCRWM following a Board workshop on deliquescence-induced localized corrosion in September 2006, and testimony presented in May 2006 by the Board's Chairman before the Senate Energy and Natural Resources Committee.
In this report, the Board summarizes its major activities from January 1, 2005, through February 28, 2006. During that period, the Board focused its attention on the Project's efforts to develop post-closure performance estimates for the repository it proposes to construct at Yucca Mountain in Nevada. Correspondence and related materials are included in the appendices to the report along with the Board's strategic plan for fiscal years 2004-2009, its performance plans for fiscal years 2005-2006, and its performance evaluation for 2005.
In this letter report to the U.S. Congress and the Secretary of Energy, the Board presents its views on the status of some important issues related to the technical basis for the U.S. Department of Energy's activities related to the waste management system, the engineered system, the natural system, the repository system, and the assessment of the performance of the systems. The Board also outlines issues that it expects may continue to be of interest in the future.
