There have been several other incidents at Chalk River Laboratories, including a 2008 radioactive leak from the NRU, but it was not deemed a risk to the public. Thankfully, the fire was put out and nobody was harmed in the immediate aftermath. The whole building was contaminated with radioactive material, which leaked to a large area outside the building when the ventilation system kicked in. As a result, there was a fuel rupture of the core and a large fire in the NRU building. Six years after the first incident in Canada, in 1958, Chalk River experienced another serious incident when a damaged fuel rod caught fire and tore apart as it was being removed from the NRU core. In April 1979, he launched the President's Commission on the Accident at Three Mile Island in a bid to understand what went wrong. His background in nuclear engineering and his experience of dismantling a reactor at Chalk River helped with this credibility. When the accident at Three Mile Island occurred over 20 years later, Carter, who was now President, inspected the nuclear plant five days after the accident in a bid to reassure people in the area (and the world) that their lives were not in any danger. with his wrench, and he had to run over to the reactor casing and he had one screw to turn. "In case, at least, he was lowered into the building. He said: "By today's standards, there's no way that would have happened. For example, he and his men worked in shifts of 90 seconds due to the radioactivity risk. Journalist and author Arthur Milnes spoke to CBC News about the conditions Carter found himself in at Chalk River. Navy volunteers all helping to deal with the aftermath. Navy officer, was part of the clear-up team which included U.S. President Jimmy Carter, who was serving as a U.S. gallons of radioactive water leaked, settling in the cellar of Chalk River Laboratories.īut, instead of the water being removed off-site, it was dumped into ditches 1,600 meters from the border of the Ottawa River, releasing 10 kilocuries (a unit and measure of radioactivity, equal to 1000 curies) of radioactive material into the area, details the Canadian Nuclear Society's report on the 1952 NRX Incident.Īt the time of the first Chalk River Nuclear accident, future U.S. ![]() The roof of the reactor was blown off, and over 1,200,000 U.S. ![]() The situation was made worse when the control rods could not be lowered into the NRX's core, with the incident further exacerbated by both mechanical and human errors. The first incident occurred on December 12, 1952, featuring a reactor meltdown and partial loss of coolant in the NRX reactor-at that time the world's most powerful nuclear research reactor.
