Within the wide selection of articles revealed by The New York Instances this week after the loss of life of former President Jimmy Carter, a fraction of largely forgotten Canadian historical past resurfaced.
The Instances’s visible story of his life, advised by way of quite a lot of objects, reveals how Mr. Carter got here to help within the cleanup of a serious nuclear accident close to Ottawa in 1952.

Among the many 17 objects, photographed by Tony Cenicola and described by Invoice Marsh, is a yellowed certificates issued in 1953 by the Knolls Atomic Energy Laboratory in New York State, proclaiming Mr. Carter an “atomic submariner.”
He was a naval officer on the time he obtained it. Mr. Carter had attended the U.S. Naval Academy from 1943 to 1946, on his strategy to changing into the primary in his household to graduate from school, and served within the submarine fleet throughout World Struggle II. Later, he was concerned within the growth of the nation’s first nuclear-powered submarines; the Knolls certificates was for finishing his coaching.
However earlier than that, Mr. Carter bought a firsthand take a look at the immense energy of nuclear vitality in Canada.
On Dec. 12, 1952, a collection of missteps and a mechanical failure led to the partial meltdown of the core of the NRX reactor on the Chalk River Laboratories on the Ottawa River, about 180 kilometers northwest of the capital. The incident gave Canada the doubtful distinction of internet hosting the world’s first nuclear reactor accident.
The NRX had a capability of 30 megawatts that day, which was highly effective by the requirements of its time (at the moment the Bruce Energy nuclear plant in Ontario churns out 6,400 megawatts).
On the day of the accident, the reactor was powered down for an inspection of its cooling system. Within the basement, a worker mistakenly raised a number of of the management rods that may cut back and, if essential, fully shut down the chain response within the reactor.
That was noticed shortly, and a supervisor thought, primarily based on some sign lights, that he had lowered the rods again in place. However the lights had been flawed: Two or three of the rods had been caught and had solely partly returned to security.
When the supervisor, who was nonetheless within the basement, phoned the management room with instructions for decreasing the rods, he additionally combined up the numbers for the buttons that wanted to be pushed, compounding the issue.
The reactor’s output soared to about 100 megawatts.
That energy surge lasted for just one minute and eight seconds earlier than the reactor was introduced again underneath management, however the injury was profound. Gasoline rods had melted or blown aside. The basement was stuffed with a million gallons of extremely radioactive water and particles. The reactor constructing, which had massive glass home windows, was dangerously radioactive.
A contingent of 150 members of the U.S. army got here to Chalk River for the cleanup. Amongst them was Mr. Carter, who led a gaggle of about 12 members of the Navy from the Knolls Laboratory. They had been joined by 862 employees on the Chalk River website, 170 members of the Canadian Military and 20 staff of firms that had made components of the reactor.
Morgan Brown, president of the Society for the Preservation of Canada’s Nuclear Heritage, which runs a museum close to Chalk River, advised me that the Individuals hadn’t been there to offer technical recommendation, because the NRX had been designed in Montreal in a joint Canadian-British challenge. However they supplied tools Canada lacked, like closed-circuit tv, and so they gained expertise and coaching for themselves in coping with the unprecedented scenario.
“The American assist was properly appreciated,” mentioned Mr. Brown, who labored for many years at NRX’s proprietor, Atomic Power of Canada, finding out methods to stop reactor disasters.
A progress report made a number of months after the Chalk River accident reveals that Lieutenant Carter, then 28, and his group labored on a “header” that fed cooling water from the river into the reactor, Mr. Brown mentioned.
In interviews, Mr. Carter recalled that his staff had used a mock-up of the reactor to observe dismantling strategies upfront and had labored in shifts to restrict publicity to radiation. A 1959 film produced by the American and Canadian governments reveals these trial runs — and means that the requirements for employee security and radioactive waste disposal had been properly under present practices.
The NRX reactor saved working till 1992. The Chalk River accident stays the worst in Canadian historical past.
The worst nuclear vitality accident in U.S. historical past, the partial meltdown of a reactor at Three Mile Island in Pennsylvania in 1979, would occur throughout Mr. Carter’s presidency. Days after the accident, he and his spouse, Rosalynn Carter, toured the plant and advised residents, “If we make an error, all of us need to err on the aspect of additional precautions and additional security.”
(For those who haven’t learn it, I like to recommend the sweeping and authoritative obituary of Mr. Carter by Peter Baker and Roy Reed.)
