Natural Resources Canada, 1996. The Policy Framework for Radioactive Waste consists of a set of principles governing the institutional and financial arrangements for the disposal of radioactive waste, including nuclear fuel waste, by waste producers and owners. The federal government has the responsibility to develop policy, to regulate, and to oversee producers and owners to ensure that they comply with legal requirements and meet their funding and operational responsibilities in accordance with approved waste disposal plans.  1, record 1, English, - Policy%20Framework%20for%20Radioactive%20Waste

Ressources naturelles Canada, 1996. La Politique-cadre en matière de déchets radioactifs énonce un ensemble de principes régissant les modes d'organisation et de financement à mettre en œuvre pour assurer l'évacuation des déchets radioactifs, y compris les déchets de combustible nucléaire, par les producteurs et propriétaires de déchets. Le gouvernement fédéral a la responsabilité de mettre en place des politiques, des règlements et des mécanismes de surveillance qui lui permettront de s'assurer que les producteurs et propriétaires de déchets se conforment aux exigences de la loi et s'acquittent de leurs responsabilités financières et opérationnelles conformément aux plans approuvés d'évacuation des déchets.  1, record 1, French, - Politique%2Dcadre%20en%20mati%C3%A8re%20de%20d%C3%A9chets%20radioactifs

Different disposal modules are used in some places for specific purposes. Pits are used for disposal of bulky, non-compactible wastes such as tanks, piping and large items of equipment. As the pit is filled, the disposed wastes are backfilled and covered with soil or concrete. Other disposal modules, such as lined shallow wells and shafts, may be provided with engineered barriers ....  1, record 2, English, - disposal%20module

Used nuclear fuel bundles would be contained in vaults 500 to 1, 000 metres below ground.

Typically, each [shallow land burial] trench has a sloping floor cut into the natural soil and a French drain of gravel down one of the long sides. The trench bottom is covered with a foot or two of sand to allow water to flow freely into the French drain, especially when the trench is open during operations. Sampling pipes or tubes are placed against the trench wall, with their lower ends in the French drain, when the trench is dug. Monitoring of each disposal unit (engineered trench) is accomplished by sampling any water found in the French drain through these tubes and analyzing its contents.  4, record 2, English, - disposal%20module

In the tunnel concept ..., the prepackaged wastes are lowered down the shaft and brought to the emplacement vaults by rail. The packages are then unloaded by forklifts or other conventional container handling equipment and emplaced for permanent disposal. The cavern concept implements a secondary haulage system where packaged wastes are transferred from rail to the emplacement vaults by overhead crane.  2, record 14, English, - tunnel
