The Hydro/AECL design team met this challenge by introducing a highly innovative containment concept-what was to become known as the negative pressure containment system. Central to the system is a large reinforced concrete building operated at a high level of vacuum(hence, the name "vacuum building"). This building is linked to the individual reactor buildings via a duct system and a number of parallel isolating valves. These valves are normally closed, permitting the reactor buildings to operate at normal atmospheric pressure. Should an accident arise, leading to a pressure rise in a reactor building, this pressure rise will actuate the isolating valves, thereby opening a flow path from the reactor building to the vacuum building. As a result, the pressure in the reactor building is quickly reduced to below atmospheric pressure, thereby positively preventing the escape to the environment of any radioactivity released inside the reactor building as a result of the accident. 1, record 1, English, - negative%20pressure%20containment%20system

An outdoor-air intake can be provided in a forced-air system, for introducing outdoor ventilation air into the structure.... This outdoor air should be conveyed through an individual duct leading from the outdoors directly to the return plenum of the furnace and should be provided with a manually-operated damper. 2, record 3, English, - outdoor%2Dair%20duct

[Chauffage à air chaud.] Gaines de prise d'air neuf (...) Dans le but de renouveler l'air des locaux, on peut reprendre de l'air à l'extérieur soit en partie, soit en totalité. Le raccord à la chaudière se fait à l'aide d'un té. Une des branches apporte l'air neuf, l'autre l'air de reprise. Un registre permet de régler la proportion d'air frais par rapport à l'air de reprise. Ce système provoque une dépense supplémentaire en combustible. En effet, il faut élever la température de l'air venant de l'extérieur à la température de soufflage. 4, record 3, French, - gaine%20de%20prise%20d%27air%20neuf

Duct system characteristics.... the basic arrangements consist of : a) The trunkduct system... b) The box-plenum duct system... c) The extended-plenum duct system... d) The individual duct system offers the other extreme in duct arrangements. This system is easy to install, but in many cases proves fairly expensive if a large number of individual ducts is to be run to a far end of the building. Furthermore, the heat loss from the ducts can be large and the duct transmission efficiency can be low. The system is easy to balance. 1, record 4, English, - perimeter%20radial%20system

Le système de périmètre genre radial utilise des gaines d'alimentation individuelles reliant la boîte centrale aux locaux à chauffer. Ce système est recommandé dans les résidences avec vide sanitaire, le plancher étant réchauffé dans une certaine mesure.
