NRX (National Research Experimental) was a heavy-water-moderated, light-water-cooled, nuclear research reactor at the Canadian Chalk River Laboratories, which came into operation in 1947 at a design power rating of 10 MW (thermal), increasing to 42 MW by 1954. It was Canada's most expensive science facility and the world's most powerful nuclear research reactor at its construction. NRX was remarkable for its heat output and the number of free neutrons it generated. In the late 1940s, the NRX reactor had the highest neutron flux in the world: 10–20 times that of a graphite reactor of comparable
