This open access book examines key aspects of international cooperation to enhance nuclear safety, security, safeguards, and nonproliferation, thereby assisting in development and maintenance of the verification regime and fostering progress toward a nuclear weapon-free world. Current challenges are discussed and attempts made to identify possible solutions and future improvements, considering scientific developments that have the potential to increase the effectiveness of implementation of international regimes, particularly in critical areas, technology foresight, and the ongoing evaluation of current capabilities.

Transforming the energy system is at the core of the dedicated sustainable development goal on energy within the new United Nations development agenda. This publication explores the possible contribution of nuclear energy to addressing the issues of sustainable development through a large selection of indicators. It reviews the characteristics of nuclear power in comparison with alternative sources of electricity supply, according to economic, social and environmental pillars of sustainability. The findings summarized in this publication will help the reader to consider, or reconsider, the contribution that can be made by the development and operation of nuclear power plants in contributing to more sustainable energy systems.

Focused attention by world leaders is needed to address the substantial challenges posed by disposal of spent nuclear fuel from reactors and high-level radioactive waste from processing such fuel. The biggest challenges in achieving safe and secure storage and permanent waste disposal are societal, although technical challenges remain. Disposition of radioactive wastes in a deep geological repository is a sound approach as long as it progresses through a stepwise decision-making process that takes advantage of technical advances, public participation, and international cooperation. Written for concerned citizens as well as policymakers, this book was sponsored by the U.S. Department of Energy, U.S. Nuclear Regulatory Commission, and waste management organizations in eight other countries.

To address the challenges posed by climate change, and to achieve the goals established in the 2015 Paris Agreement, nuclear power has been identified to have great potential to contribute to the 1.5°C climate change mitigation target. This topical conference on climate change and the role of nuclear power, the first of its kind, served as a unique forum for exchanging science-based information on the role of nuclear power in supporting the low carbon energy transformation and for conducting objective discussions on the opportunities and challenges of safe, secure and safeguarded nuclear technology development. The major themes of the conference covered energy and climate change policies, implications for the power sector, environmental perspectives and potential roles of existing, evolutionary and innovative nuclear power systems, including the integration of nuclear/renewable energy systems. In addition to nuclear power's interim and long term contributions, some strategic and cross-cutting issues relating to public perception, regulations, markets and finance were also addressed. These proceedings provide a summary of the different plenary, technical and side event sessions as well as the full text of the speeches delivered in the opening, closing and high-level plenary sessions of the conference.
