Record 2 - external organization data 2010-09-27

English

Subject field(s)
  • Chemistry
  • Compartment - Canadian Nuclear Safety Commission
CONT

… the moderator and coolant [are] separated by two tubes with a donut shaped space(annulus) between them. The calandria tubes, about six meters long, are the walls of the channels through the calandria. The pressure tubes, placed inside the calandria tubes, each contain 12 or 13 fuel bundles. The gas in the space between the tubes, the annulus gas, insulates the cool moderator from the hot heat transport system.

  • Tiroir - Commission canadienne de sûreté nucléaire
CONT

[…] le modérateur et le caloporteur […] se présentent dans des circuits distincts séparés par deux tubes dans un espace en forme de beigne (espace annulaire). Les tubes de calandre, d’environ 6 mètres de longueur, sont les parois des canaux de la calandre. Les tubes de force, placés à l'intérieur des tubes de calandre, renferment chacun 12 ou 13 grappes de combustible. Le gaz contenu dans l’espace entre les tubes, appelé gaz annulaire, isole le modérateur froid du circuit caloporteur chaud.

Record 5 2004-07-15

English

Subject field(s)
  • Oil Drilling
CONT

An operator shall ensure... that a sour well, producing with a gas concentration greater than 50 moles per kilomole, a disposal well, or an injection well is not placed on production or injection unless the annulus between the production casing and tubing is effectively isolated from the completion interval...

OBS

sour: Contaminated with sulfur or sulfur compounds, especially hydrogen sulfide. Crude oil and gas that are sour typically have an odor of rotten eggs if the concentration of sulfur is low. At high concentrations, sulfur is odorless and deadly.

Record 6 1978-09-07

English

Subject field(s)
  • Gas Welding
  • Arc Welding
CONT

The course includes ... acetylene welding of aluminium castings, argon tungsten arc welding, argon metal arc welding ...

OBS

In... gas-shielded tungsten-arc welding an inert gas-usually argon-flows from an annulus surrounding the torch in a continuous stream, displacing the air from around the arc. The gas does not chemically react with the metal but simply protects it from contact with the oxygen in the air.

OBS

In the early applications of the inert gas arc welding, a non-consumable tungsten electrode was used for striking the arc ... This method is widely used for welding aluminium, stainless steel, magnesium ...

CONT

Dans le procédé de soudage sous argon appelé TIG (de l'expression anglaise Tungsten Inert Gas), l'électrode non consommable en tungstène est placée au centre d'une buse alimentée en argon [...]

CONT

Les procédés de soudage sous argon TIG et MIG [Metal Inert Gas] sont utilisés pour souder dans de très bonnes conditions l'acier inoxydable et les alliages légers [...]

OBS

Un certain nombre de procédés utilisent un arc en atmosphère contrôlée soit inerte, soit active. Dans le procédé TIG [...] l'atmosphère est un gaz inerte (hélium, argon) pour protéger l'électrode [...]
