Nuclear Power Demonstration reactor. This was the prototype CANDU reactor, and the first power reactor in Canada. It was located upstream of AECL' s Chalk River laboratories, along the Ottawa River's south shore(i. e. in Ontario). The reactor had a maximum continuous output of 22 MWe gross(19. 5 MWe net)... The reactor was built as a joint AECL/Ontario Hydro/Canadian General Electric project, and was initially intended to use a vertically-fuelled pressure vessel reactor. The design was changed in 1957 to natural uranium fuel bundles in horizontal pressure tubes in unpressurized heavy water moderator, with on-line refuelling. These are hallmarks of the CANDU reactor. The reactor had 132 fuel channels(each fuel channel comprised a pressure tube inside a calandria tube) and the coolant leaving the channels was 7. 2 MPa and 277°C. The main reactivity control was by adjusting the heavy-water moderator level, which could be rapidly dumped for fast shut down. NPD was finally shut down on May 5 1987, for economic reasons... 4, record 2, English, - nuclear%20power%20demonstration%20reactor

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 3, English, - negative%20pressure%20containment%20system

Afin de localiser et repositionner les patins d'espacement qui se sont déplacés, EACL et Ontario Hydro ont formé une équipe chargée de concevoir un robot télécommandé piloté par ordinateur. Construit et éprouvé au laboratoire, l'appareil de localisation et de repositionnement des patins d'espacement (SLAR) ouvre chaque canal de combustible et y insère un outil spécial qui localise les patins, mesure l'écart entre les deux tubes et, à l'aide d'ultrasons et de courants de Foucault, détecte les soufflures dans les parois de métal. L'outil en question comporte des vérins hydrauliques permettant d'écarter les tubes pour dégager les patins (...) 1, record 5, French, - appareil%20de%20localisation%20et%20de%20repositionnement%20des%20patins%20d%27espacement
