FOREWORD Since 2009, the expected growth of nuclear power worldwide has led to an ongoing increase in uranium demand. Notwithstanding significant price fluctuations, uranium production has increased over the past several years, and many new projects are now under consideration. Negative legacies of past uranium mining activities have the potential to impact current and proposed uranium mining projects, in particular their ‘social licence’. Much work has been done to remediate those negative effects in many mining districts, although much remains to be done. Moreover, some currently operating mines are nearing the end of their active lives and will move into rehabilitation in the next few years with a need to avoid new legacy issues. The IAEA undertakes numerous activities to support its Member States throughout the life cycle of uranium production and in the remediation of legacy sites. In the 1990s, the IAEA began working with the Uranium Mining and Remediation Exchange Group (UMREG), an informal international assemblage of uranium mining professionals that brings together practitioners from all sides of the uranium mining industry to discuss ideas and exchange experiences related to remediation and legacy site management, and operational mining projects. In 2011, the IAEA published a volume of collected papers entitled UMREG Uranium Mining and Remediation Exchange Group: Selected Papers 1995–2007. In 2012, the IAEA began a further series of nine Technical Meetings on the theme of good practice in the uranium production cycle, including an UMREG meeting hosted by the IAEA at its Headquarters in Vienna. The committee advising the IAEA for these Technical Meetings urged publication of a second volume of collected UMREG papers, and so the proceedings of the UMREG meeting were expanded to include selected papers from other Technical Meetings within the series. The present publication is intended to be a record of the work done in many Member States and presented at UMREG and other relevant Technical Meetings over the period 2012–2015. It includes all of the papers received, in the order in which the original presentation was made. For the majority of the papers, the work has been updated since the original presentation, and the title and authorship may vary slightly to reflect this. The IAEA officers responsible for this publication were P. Woods and M. Fairclough of the Division of Nuclear Fuel Cycle and Waste Technology.
