In underground repositories for radioactive waste, significant quantities of gases may be generated as a result of several processes. The potential impact of gas generation, accumulation and migration on the performances of the various barriers and, ultimately, on the long-term safety of a repository, should therefore be assessed in the development of safety cases for underground repositories. It was in this context that the EC and the NEA organised a workshop on "Gas Generation, Accumulation and Migration in Underground Repository Systems for Radioactive Waste: Safety-relevant Issues" in Reims, France on 26-28 June 2000. This book includes the texts of the invited presentations, the reports of the deliberations held in the five working groups, as well as the main conclusions of the workshop.
Female scientists and engineers pioneered the nuclear and radiological fields, with leaders and innovators such as Marie Skłodowska-Curie and Lise Meitner, among many others, establishing the foundation of modern nuclear science and technology. Women continue to make vital contributions to the sector, but their visibility and overall numbers in the sector remain limited, especially in science, technology, engineering, and mathematics (STEM), and leadership roles. The lack of diversity in the sector represents a loss of potential innovation and growth and a critical threat to the viability of the field.
This report features the first publicly available international data on gender balance in the nuclear sector. The data was collected from over 8 000 women in the nuclear workforce in 32 countries, as well as human resources data from 96 nuclear organisations in 17 countries. Based on the findings, a comprehensive, evidence-driven policy framework is proposed with practical recommendations.
One of the challenges facing the continued availability of nuclear energy is that of ensuring the safe, environmentally acceptable and economic management of the waste generated during its production.
There is a broad scientific and technical consensus that disposal of high-level, long-lived radioactive waste in deep geologic formations is an appropriate and safe means of isolating it from the biosphere for very long time scales. There have, however, been setbacks in the disposal programmes in many countries, primarily due to the failure of the waste management community to win sufficient public and political support.
This report, which is based on recent work of the OECD Nuclear Energy Agency (NEA), reviews the progress to date in this field and the further steps that may be required to implement geologic disposal, taking into account both the technical and regulatory requirements, and the need to achieve an appropriate level of societal acceptance.
This book should be of interest to government and industry decision makers, academics and all those eager to better understand what is at stake in this widely debated subject and the prospects that emerge.
The concept of removing long-lived radioactive wastes from the human environment by disposal in deep geological repositories was developed several decades ago. In the intervening years, research efforts world-wide have increased our knowledge and understanding of how underground disposal systems will function over very long periods of time. Significant progress has also been made towards implementation of such facilities. There have, however, been delays in the disposal programmes of several countries. This report is a review of developments in the past decade. The primary sources of information are the answers to a questionnaire provided by waste management organisations represented in the NEA Radioactive Waste Management Committee (RWMC). The latter is an international forum of senior specialists from safety authorities, waste management agencies, R&D institutions and policy-making bodies.
When preparing the safety case for a deep geological repository of radioactive waste, the integration of wide-ranging information from multidisciplinary sources is a complex task. This has provided the motivation for establishing AMIGO, an OECD/NEA international project on “Approaches and Methods for Integrating Geological Information in the Safety Case”. AMIGO is structured as a series of biannual topical workshops involving site characterisation and safety assessment practitioners with experience in both sedimentary and crystalline rock settings.
The first AMIGO workshop was organised in Yverdon-les-Bains, Switzerland on 3-5 June 2003. The main objective of the workshop was to exchange views on building confidence in analyses and arguments that support the safety case using multiple lines of evidence and integrating the work of geoscientists and safety assessors. These proceedings present the outcomes of this workshop.
This conference proceedings brings together the latest knowledge on political and technical progress in geological repositories for radioactive waste. It presents perspectives from a variety of countries and stakeholders, examines international instruments being used to facilitate the implementation of geological repositories, and assesses scientific progress and pending technical issues.
Plant life management is becoming an increasingly important topic both in nuclear power plant operations and in international discussions on the role of nuclear energy. As in many other aspects of nuclear power plant operations there is much to be learned by international comparisons of practices. This five-language glossary of terminology (English, French, German, Russian, Spanish) is intended to assist utility operators and regulators in OECD countries, and more generally to help readers benefit as much as possible from international experience.
The main objective of national energy policies in OECD countries is to ensure the availability of secure and economic supplies with minimal environmental impact. This publication addresses the roles and responsibilities of governments in the field of nuclear energy, within the context of broad national policy goals, and reviews the tools available to achieve those goals.
Peer reviews are a standard co-operative OECD working tool that offer member countries a framework to compare experiences and examine best practices in a host of areas. The OECD Nuclear Energy Agency (NEA) has developed a proven methodology for conducting peer reviews in radioactive waste management and nuclear R&D. Using this methodology, the NEA Radioactive Waste Management Committee’s Working Party on Decommissioning and Dismantling (WPDD) developed the present guide as a framework for decommissioning cost reviewers and reviewees to prepare for and conduct international peer reviews of decommissioning cost estimate studies for nuclear facilities. It includes checklists that will help national programmes or relevant organisations to assess and improve decommissioning cost estimate practices in the future. This guide will act as the NEA reference for conducting such international peer reviews.
