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 3, English, - nuclear%20power%20demonstration%20reactor
