Session: Uranium Tailings Management

ABSTRACT: AREVA Resources Canada Inc., (AREVA) is the operator of the McClean Lake Operation and recently undertook a project to expand the storage capacity of the existing JEB Tailings Management Facility (TMF). The expansion of the TMF involved raising the maximum allowable tailings elevation in the pit. The geometry of the TMF is such that raising the tailings elevation increased the surface area, adding to the amount of atmospheric water infiltrating into the tailings. An engineered soil cover and landform were designed to limit the infiltration of atmospheric water into the tailings. The soil cover and landform needed to promote the sustainable management of surface water through run off and evapotranspiration, while subject to the climate conditions in northern Saskatchewan. The paper describes how the soil cover and landform design were undertaken to meet the requirements of the expansion project.

RÉSUMÉ: AREVA Resources Canada Inc. (AREVA) est l'opérateur de l'établissement de McClean Lake et a récemment entrepris un projet pour agrandir l'installation de gestion des résidus (IGR) de JEB pour augmenter le volume du stockage des résidus produits par les activités de préparation du minerai. L'expansion de l'IGR a impliqué élever l™élévation maximum de résidus permis dans la fosse. La géométrie de l™IGR est telle qu™élever l™élévation maximum de résidu augmente la région de la surface et ajoute à l™infiltration d'eau de l'atmosphère dans les résidus. Une couverture de sol et un relief ont été conçus pour limiter l'infiltration. La couverture du sol et le relief devaient être conçu pour promouvoir la gestion durable des eaux de surface par ruissellement et évapotranspiration, tout en étant soumis à des conditions climatiques dans le nord de la Saskatchewan. L'article décrit comment la conception de la couverture du sol et le relief ont été entrepris selon les exigences du projet d'expansion.
