[en] Full text: The presentation ''Remediation of uranium sites in Niger'' covers the following aspects: 1. Geographical framework; 2. Institutional framework; 3. Legislative and regulatory framework; 4. Mining activities; 5. Remediation: COMINAK case study; 6. Challenges. Part 1 deals with the geographical situation of Niger with some general statistics data. Part 2 presents the institutions involved in the activities of control and monitoring of the mining sector. Part 3 concerns the legislative and regulatory framework in relation to of uranium sites remediation issues In Part 4 are described ongoing uranium activities and projects which will start one or two years. Part 5 focuses on a case study: COMINAK site remediation project. Are developed the following elements: the general principles, the methodology, identification of source terms, the risks and the measures programmed or already taken to mitigate risks, constraints faced in the implementation of remediation project Part 6 deals with challenges, especially regarding the lack of legislation for remediation fund mobilization and management.

[en] This paper briefly examines how indigenous engagement by Australian mining companies has evolved over the past 50 years and highlights some of the negative consequences that can arise from ineffective cross-cultural consultation. A special focus is placed on uranium mining and milling and a specific engagement strategy for the Ranger Uranium Mine is discussed as a case study. From this, a more general strategic approach based on cultural recognition is proposed. Outcomes for the Ranger Uranium Mine have so far been promising, but further work is required to determine if the general strategic approach will be successful. (author)
[en] The current work tries to achieve the objectives of the work by considering a watershed where all drainage concentrates to one outlet. The area of the watershed is 20.235 km2. The total length of the main stream is 3.44 Km. Elevation at the upper most cross section was 1015 m a.s.l. to the point where discharge would be measured was 722 m.a.s.l. Keeping in view of the above points the following are the objectives the current work would try to achieve: Design field experiments for data acquisition and development of scientific database for run-off and erosion prediction in hilly and complex terrain; To establish the relationship between rainfall and runoff in order to assess runoff at various intensities of rainfall; To examine the effects of slope, soil and land use/land cover on runoff and sediment flow, and To estimate the rainfall-runoff-sediment responses during extreme events
[en] Namibia has implemented mutually-beneficial partnerships to ensure that adequate capacity exists. Voluntary product stewardship schemes have arisen out of the need for the industry to balance their pursuit of economic gain with environmental and social concerns. Industry has built on World Nuclear Association standards in developing voluntary product stewardship schemes to gain majority sector participation. (author)
[en] Uranium mines in China has partly entered the phase of decommissioning. Basic situation of the decommissioning management and environmental monitoring results of final completion and acceptation in an uranium mine is presented in this paper. The problems of decommissioning management and final completion have been discussed, and suggestions have been provided. (authors)
[en] The closure plan for the Caldas uranium mining and milling site (Brazil) is in its first stages and will involve the licensing and supervision of a big scale environmental remediation project (ERP). During this process, the team from LAPOC/CNEN involved with the licensing of the site has identified the need for professionals from various specialties to conduct the necessary assessments. In this context, this work aims to map the critical knowledge necessary for the challenge presented above and also to identify if the regulator counts with experts who possess such knowledge. Next, to share the knowledge and information needed to carry out assessments, the creation of a Community of Practice (CoP) is suggested. (author)
[en] This CD-ROM contains tables of empirical characteristics of selected proterozoic unconformity uranium deposits and systems and tables of individual deposits and systems, grouped by region and by deposit type.
[en] This paper gives World Nuclear Association (WNA) views on nuclear capacity additions to 2030 and the likely adequacy of the fuel supply chain to meet the nuclear fleet’s uranium requirements, as presented at the URAM-2014 symposium. A scenario approach is adopted resulting in three capacity projections based on the outlook for existing and new nuclear countries. Uranium resource estimations are taken from the OECD-NEA/ IAEA Red Book and the prospects for new and existing mines assessed on a site-by-site basis. Both prospective uranium requirements and primary uranium supply have decreased since the WNA’s previous 2011 report, the latter markedly so from the mid-2020s. Secondary supply is also projected and expected to remain high to 2030. (author)
[en] The Gunnar and Lorado mine and mill sites were two of the largest, legacy uranium mine sites that were developed and operated during the Cold War years. Traditional hunting, trapping and fishing activities are presently practiced in areas close to these sites. Multiple and meaningful interactions started at the initial remediation planning stages and continued through the setting of project objectives, approval stages and implementation. SRC's procurement team used significant weighting tools to ensure residents would be directly involved in, trained, employed, and benefit from the remediation work. Partnerships with local First Nations, Metis and the Prince Albert Grand Council were/are essential for meaningful socio-economic benefits in this area. The discussion: Engagement activities for this project went beyond the legal Duty to Consult requirement for Aboriginal consultation - did the benefits increase accordingly? Where to from here? How can processes and programs be improved to increase joint benefits? (author)
[en] The Unidade de Tratamento de Minérios (UTM, Ore Treatment Facility) was the first uranium ore mining and ore production site to operate in Brazil. Twenty years after ceasing operations, the site is going through an environmental restoration and decommissioning process, which is to be conducted by the operator and regulated by the national nuclear and environmental authorities. The UTM case can be identified as a typical uranium mining operation carried out before restrictive licensing procedures and environmental laws became a trend around the world. This paper aims to present the current status of the site and some of the challenges to be faced by the parties involved in the decommissioning process.
