This report highlights the potential role of nuclear in contributing to the circular carbon economy as a low-carbon source of electricity, but also as a source of heat and system integration services. It further highlights the essential role played by the existing nuclear reactor fleet in...

This publication provides comprehensive information on the regulatory and institutional frameworks governing nuclear activities in the United Kingdom. It examines the general regulatory regime, including mining, radioactive substances and equipment, nuclear installations, trade in nuclear...

Meeting the growing demand for energy, and electricity in particular, while addressing the need to curb greenhouse gas emissions and to ensure security of energy supply, is one of the most difficult challenges facing the world’s economies. No single technology can respond to this challenge,...

This report communicates the results of an international seminar which reviewed recent progress in the field of pellet-clad interaction in light water reactor fuels. It also draws a comprehensive picture of current understanding of relevant phenomena and their impact on the nuclear fuel rod,...

In the context of sustainable development policies, decision making in the energy sector should be based on carefully designed trade-offs which take into account, insofar as feasible, all of the alternative options’ advantages and drawbacks from the economic, environmental and social...

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...

During irradiation, nuclear fuel changes volume, primarily through swelling. This swelling is caused by the fission products and in particular by the volatile ones such as krypton and xenon, called fission gas. Fission gas behaviour needs to be reliably predicted in order to make better use of...

This report outlines international efforts to strengthen nuclear regulation, safety, research and radiological protection in the post-Fukushima context. It also highlights key messages and lessons learnt, notably as related to assurance of safety, shared responsibilities, human and...
