ABSTRACT: Atomic Energy of Canada Limited's (AECL) Underground Research Laboratory (URL), located 150 km northeast of Winnipeg, Manitoba, is currently being decommissioned and its underground facilities permanently closed. As part of the URL closure, shaft seals have been installed at a depth of approximately 275 m at the intersections of the main shaft and ventilation raise with a deep fracture zone. The installation of these seals provides a unique opportunity to study the behaviour of a functional full-scale shaft seal. The Enhanced Sealing Project arose from this opportunity and consists of the installation and monitoring of a suite of sixty eight (68) instruments installed in the main shaft seal.
RÉSUMÉ: Le Laboratoire de recherches souterrain (LRS) d'Énergie atomique du Canada limitée (EACL), qui se trouve à 150 km au nord-est de Winnipeg (Manitoba), est présentement en cours de déclassement et ses installations souterraines seront fermées définitivement. Lors de la fermeture du LRS, on a installé dans les puits des joints d'étanchéité à une profondeur d'environ 275 m aux points de croisement du puits principal et du puits d'aération avec une zone de fracture profonde. L'installation de ces joints offre une occasion unique d'étudier le comportement d'un joint d'étanchéité de grandeur nature pour les puits. Le Projet d'amélioration de l'étanchéité résulte de cette possibilité; il consiste à installer et à surveiller un ensemble de soixante-huit (68) instruments installés sur le joint d'étanchéité du puits principal.
