English

Subject field(s)
  • Waste Management
  • Nuclear Waste Materials
CONT

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 ....

CONT

The concept [burying the waste deep underground in the Canadian Shield] isolates used fuel from the environment using a series of natural as well as manmade barriers. Used nuclear fuel bundles would be contained in vaults 500 to 1,000 metres below ground. These vaults would consist of a network of tunnels and disposal rooms about 2 kilometres by 2 kilometres that could hold 191,000 tonnes of used fuel.

CONT

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.

CONT

... the aboveground vault is a large steel-reinforced concrete structure with vertical access (through an open top) for placement of the waste. Within each structure there are numerous disposal units. Each disposal unit is sealed when filled to capacity. Individual units are sized to accommodate waste deliveries for about 1 to 2 weeks.

French

Domaine(s)
  • Gestion des déchets
  • Déchets nucléaires
CONT

C'est l'association des propriétés cumulées du déchet, de sa matrice d'enrobage ou de blocage et, dans certaines conditions, de l'enveloppe des colis et des éléments constitutifs des modules de stockage (plates-formes et alvéoles), qui constitue le premier système de barrières d'isolement des déchets.

CONT

Pour les déchets d'activité moyenne, des monolithes de béton peuvent être obtenus à partir de tranchées bétonnées dans lesquelles on dispose les déchets et qui sont ensuite obturées par injection d'un coulis de ciment. Pour les déchets de faible activité, on peut constituer un tumulus sur des aires aménagées, planes, bétonnées et drainées. La figure 18 montre schématiquement l'exemple d'un stockage mixte tumulus sur monolithe. On y voit le réseau de canalisations enterrées qui ceinture chaque module de stockage et qui est destiné à contrôler l'efficacité des barrières et en particulier de la couche argileuse. [...] Les tumulus comprennent les blocs de béton en rangées de 5 m de haut constituant des cellules de 10 m X 30 m.

CONT

Subject field(s)
  • Pipes and Fittings
  • Plumbing Fixtures
DEF

Back vent. A pipe or system of pipes connected to the drainage pipes of a plumbing system for the purpose of supplying or removing air to relieve pressures above or below atmospheric. A back vent is that part of a vent line which connects directly with an individual trap beneath or behind a fixture and extends to a branch or main soil or waste pipe at any point higher than the fixture or fixture trap it serves.

DEF

Anti-siphonage pipe. An air pipe in a plumbing system which admits air downstream of a water seal in a w. c., sink or washbasin, thus preventing the creation of a vacuum in the wake of water flushed down the drain and avoiding the breakage of the seal which such a vacuum could cause. The top of an anti-siphonage pipe may be connected to a ventilation pipe.

DEF

Vent pipe. Any small pipe extending from any of the various plumbing fixtures in a structure to the vent stack.

OBS

Back vent ... sometimes called an individual vent.

DEF

Ventilation secondaire. Tuyau amenant l'air nécessaire pendant les évacuations et empêchant l'aspiration de la garde d'eau des siphons.

DEF

Évent de siphonnement. Évent particulier d'un siphon.

DEF

Branchement de ventilation secondaire. Canalisation repiquée sur le siphon d'un appareil ou sur son branchement d'évacuation.

CONT

On distingue les ventilations primaires, qui équipent obligatoirement toutes les chutes et descentes, et les ventilations secondaires qui, raccordées sur les premières, constituent des prises d'air pour les siphons, évitant ainsi leur désamorçage par l'aspiration créée dans la chute.

CONT

Les siphons sont susceptibles de se désamorcer. La norme suivante a été établie : P 41-201. Évacuation des eaux usées. Ventilation secondaire [...] Ce dispositif est obligatoire pour tous les appareils autres que les W.C. raccordés sur une chute unique et dans le cas d'installation de plusieurs appareils branchés sur une même dérivation d'écoulement.

OBS

Lorsqu'on a affaire, d'une part à une descente qui ne reçoit que des lavabos bidets, baignoires, éviers et autres appareils de même nature et d'autre part à une chute qui ne reçoit que des W.-C., on se contente de les ventiler chacune par le haut en les prolongeant hors combles dans le même diamètre : c'est ce qu'on appelle la ventilation primaire. Si l'on réunit descente et chute en une chute unique la norme fait obligation d'établir une ventilation spéciale pour tous les siphons des appareils autres que les W.-C. : c'est ce qu'on appelle la ventilation secondaire. Quand il y a plusieurs appareils les ventilations sont raccordées à un réseau dit réseau de ventilation secondaire.

OBS

Strictement parlant, les termes «ventilation secondaire», «dispositif de ventilation secondaire», «évent de siphonnement» ou «anti(-)siphonnage» doivent être considérés comme des génériques englobant la «colonne de ventilation secondaire», tuyau vertical repiqué sur la chute, et le «branchement de ventilation secondaire», tuyau horizontal légèrement incliné, repiqué sur la colonne de ventilation secondaire ou sur la chute.

CONT

Monitoring wells should effectively achieve one or more of the following objectives: Provide access to the groundwater system for collection of water samples ... Measure the hydraulic head at a specific location in the groundwater flow system ... Provide access for conducting tests or collecting information necessary to characterize the aquifer materials or their hydrologic properties.

OBS

Figure 6. 1 illustrates a typical open disposal trench at the Barnwell facility. The trench floor is sloped slightly and covered with a layer of sand to facilitate collection of percolating water in a French drain. A number of pipes allow any water that may collect in the French drain to be removed and analyzed. Presently waste, primarily in boxes, drums and cask liners, is stacked neatly in the trench... As the level of the waste reaches the design level, 2 m below grade, a layer of dry soil is added and allowed to filter down between the waste containers. When a trench is filled, it is covered with a cap of at least 0. 6 m of compacted native clay, followed by at least 0. 9 m of soil. The cap is graded to shed water and seeded with grass. The sump in each trench is monitored for at least 5 years and any subsidence in the cap is filled to maintain its water-shedding ability. Monitoring wells at the perimeter of the facility have not detected migration of nuclides after more than 15 years of operation.

Subject field(s)
  • Sewers and Drainage
CONT

The downspout takes the water from the gutter and down to the drainage pipe or splash block on the ground... If your downspout drains into an underground drain pipe, it is wise to use some kind of stainer in the eavestrough to prevent debris from clogging the underground pipe. If you do not use underground drainage, use a piece of downspout and an elbow to direct the water away from the house and dump onto a splash block.

CONT

Rain and melted snow on the roof are collected by the eavestroughs and channeled to the ground by downspouts. These downspouts are then connected to an extension pipe or splash pad which carries the rainwater away from the house, ensuring that it does not soak into the ground close to your house.

DEF

Fluid-fluid heat exchanger made of two concentric pipe sections; one fluid (such as a coolant) flows in the annular space between pipes, and the other fluid (such as hot process stream) flows through the inner pipe.

CONT

The condenser is also a Model no. 06036 shell and tube exchanger, identical to the reboiler with a few modifications : The baffles have been cut at the bottom where they meet the shell to allow condensate to flow out of the shell. The tube side has four passes for maximum heat transfer on the tube side. It is mounted nearly horizontally. The inlet end is a couple of inches higher than the outlet to allow condensate to drain out the low end. A few tubes have been removed at the top to give the vapor more room to distribute itself along the length of the shell. There is a vent on the shell side near the outlet end to allow non-condensable gases to leave. The vent gases pass through the inside of a 36" double pipe condenser so that any condensable gasses will condense out and run down the walls back into the condenser.

A number of pipes allow any water that may collect in the french drain to be removed and analyzed. Presently waste, primarily in boxes, drums and cask liners, is stacked neatly in the trench, starting at the high end and progressing toward the low end. High specific activity waste is usually placed at the bottom of the trench. A separate narrower shielded trench is used at Barnwell for waste that has very high dose rates at the package surface. As the level of the waste reaches the design level, 2 m below grade, a layer of dry soil is added and allowed to filter down between the waste containers. When a trench is filled, it is covered with a cap of at least 0. 6 m of compacted native clay, followed by at least 0. 9 m of soil.

Join the volunteers who are painting yellow fish symbols beside sewers with local municipal approval. They also distribute fish-shaped brochures to remind people to dispose of household hazardous wastes in an environmentally-sound way. Each year, Canadians dump 300 million litres of used motor oil into the environment, with "down the storm drain" being one possible route of contamination. Most water that runs down the storm drains will flow directly into nearby creeks, rivers and lakes. The water goes down the storm drains ends up being the next town's drinking water. People may not realize that by using storm drains as "handy" places to dump unwanted household hazardous products, they are polluting the water. Responsibly disposing of household chemicals and automotive and lawn care products protects both our environment and our health. To date, the program has been approved by over 130 municipalities in Ontario. Since 1993, over a quarter of a million households in Ontario have been reached by the program.
