Within the wide selection of articles printed 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, informed by 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 solution to turning into the primary in his household to graduate from faculty, and served within the submarine fleet throughout World Struggle II. Later, he was concerned within the improvement of the nation’s first nuclear-powered submarines; the Knolls certificates was for finishing his coaching.
However earlier than that, Mr. Carter acquired a firsthand take a look at the immense energy of nuclear power in Canada.
On Dec. 12, 1952, a sequence 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 (in the present day 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 employee mistakenly raised just a few of the management rods that may cut back and, if crucial, utterly shut down the chain response within the reactor.
That was noticed rapidly, and a supervisor thought, primarily based on some sign lights, that he had lowered the rods again in place. However the lights have been unsuitable: Two or three of the rods have 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 blended 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 harm was profound. Gas rods had melted or blown aside. The basement was crammed 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 bunch of about 12 members of the Navy from the Knolls Laboratory. They have been joined by 862 employees on the Chalk River web site, 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, informed me that the People hadn’t been there to provide technical recommendation, because the NRX had been designed in Montreal in a joint Canadian-British venture. However they offered tools Canada lacked, like closed-circuit tv, and so they gained expertise and coaching for themselves in coping with the unprecedented state of affairs.
“The American assist was nicely appreciated,” mentioned Mr. Brown, who labored for many years at NRX’s proprietor, Atomic Vitality of Canada, learning methods to stop reactor disasters.
A progress report made just a few months after the Chalk River accident exhibits 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 crew had used a mock-up of the reactor to follow dismantling strategies upfront and had labored in shifts to restrict publicity to radiation. A 1959 movie produced by the American and Canadian governments exhibits these trial runs — and means that the requirements for employee security and radioactive waste disposal have been nicely under present practices.
The NRX reactor stored working till 1992. The Chalk River accident stays the worst in Canadian historical past.
The worst nuclear power 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 informed residents, “If we make an error, all of us wish to err on the facet of additional precautions and additional security.”
(In the event you haven’t learn it, I like to recommend the sweeping and authoritative obituary of Mr. Carter by Peter Baker and Roy Reed.)
