A bunch of U.S.-based scientists has despatched a second open letter to Prime Minister Justin Trudeau requesting an professional evaluate of a New Brunswick nuclear mission over its plans to recuperate a radioactive materials from spent uranium gasoline.
The letter cites issues in regards to the course of being proposed to recuperate radioactive plutonium from gasoline utilized in nuclear reactors. The scientists fear the plutonium, and the know-how related to it, may fall into the improper fingers and be used to supply nuclear weapons, arguing statements from the mission’s backers saying the other are deceptive.
Moltex Vitality, a personal firm primarily based in Saint John, obtained a $50.5-million federal grant in March to construct a nuclear processing plant, which might recuperate plutonium combined with different substances. The plant is slated for completion within the early 2030s.
The Moltex mission raises alarms amongst these against the nuclear business. Any course of involving plutonium manufacturing is dangerous due to its extraordinarily excessive radiation, and the dangers related to this specific enterprise received’t be recognized till an professional evaluate is performed, says Susan O’Donnell, a College of New Brunswick researcher and member of the Coalition for Accountable Vitality Growth.
Nuclear gasoline reprocessing, which extracts plutonium from used nuclear gasoline, has by no means been executed commercially in Canada. Plutonium is shaped through the nuclear fission course of inside a nuclear reactor. When the fission is stopped, irradiated gasoline bundles containing the plutonium are cooled in swimming pools of water for a few decade after which transferred to dry storage containers. This course of has been happening for nearly 40 years at New Brunswick’s Level Lepreau Nuclear Producing Station. The used gasoline in dry storage is in ageing concrete silos.
Nonetheless, O’Donnell explains Moltex is proposing to open the silos at Level Lepreau, which comprise dry used gasoline, and dissolve the gasoline bundles in molten salt, turning them right into a liquid and extracting the plutonium, which will probably be used to gasoline a brand new sort of reactor nonetheless within the design stage.
“Plutonium is simply created inside a nuclear energy reactor. You possibly can’t mine it or something like that. And it is one of the crucial harmful supplies on Earth, as a result of each nuclear warhead requires a plutonium set off,” stated O’Donnell.
“That is what the issue is: It is completely important for nuclear bombs … technically it may also be used to gasoline nuclear reactors, however we do not try this in Canada.”
Many issues echo the initial letter despatched out in Might, whose signatories embrace Peter Bradford, former member of the U.S. Nuclear Regulatory Fee and Vermont Legislation Faculty professor; Steve Fetter, previous chief of nationwide safety and worldwide affairs within the Workplace of Science and Expertise Coverage on the White Home; and others.
Their main argument is that the plutonium, which Moltex says will probably be used to energy its molten salt-cooled reactors, is a severe menace to nuclear proliferation — the unfold of nuclear weapons — and the atmosphere.
Though the federal government says nuclear energy is a part of the local weather disaster answer, many environmental teams say it shouldn’t be. The Inexperienced Celebration of Canada has spoken out about molten salt reactors just like the one Moltex plans to construct, calling them pricey, unproven and environmentally harmful.

The signatories say they obtained no response again from the Canadian authorities aside from getting phrase their preliminary letter had been referred to the ministers of international affairs and pure assets. Nonetheless, Moltex posted a rebuttal to the preliminary issues on its firm web site.
The publish begins off by saying the corporate agrees “Canada ought to proceed to evaluate our know-how utilizing impartial consultants. We’re open and clear and will probably be participating professional evaluations throughout all disciplines together with safeguards and safety over the approaching years prematurely of testing and deployment.”
It goes on to say the corporate’s processing amenities won’t have the capability to supply nuclear weapons as a result of the plutonium extracted will probably be combined with different supplies.
In an e mail to Canada’s Nationwide Observer, Moltex Vitality’s director of communications stated issues round nuclear weapons are “unfounded” for that motive.
“Standard reprocessing amenities are designed to supply pure plutonium, which is what’s required to supply nuclear weapons,” stated Erin Polka.
“Our recycling facility can’t produce pure plutonium — nor may or not it’s modified in any approach to have the ability to produce pure plutonium — and is due to this fact ineffective in weapons manufacturing.”
Nonetheless, the signatories of the 2 letters, who’re all non-proliferation consultants, aren’t satisfied.
They level to a 2009 study, which they are saying discovered Moltex’s declare to be false: It wouldn’t be not possible to purify the plutonium. After explaining the method, they write: “Because of this, purifying the plutonium would require solely the capabilities of a comparatively low-cost and small laboratory sizzling cell, not a multibillion-dollar ‘typical reprocessing plant’ as Moltex asserts.”
The consultants additionally cite environmental issues, which Gordon Edwards, nuclear professional and co-founder of the Canadian Coalition for Nuclear Duty, shares.
He says among the most radioactively contaminated locations on Earth are the websites the place large-scale nuclear processing has taken place, resembling in England, the place the Windscale hearth noticed a three-day accident lead to radioactive fallout throughout Europe.
Proliferation, the atmosphere and all the danger related to plutonium make a mission like this worrisome for Edwards.
“For Canada to start out separating plutonium at this stage within the recreation, is de facto upsetting …There’s a long-standing warning from individuals within the non-proliferation discipline, individuals within the nuclear disarmament space, that that is simply sending a foul sign,” stated Edwards.
“That if Canada goes to be separating plutonium, then why could not any nation on the planet do it?”
