My name is Theresa McClenaghan. I will be speaking English this evening.
Thank you very much for inviting the Canadian Environmental Law Association to speak to you as a witness today on this important study on reusing materials and supporting a circular economy.
The Canadian Environmental Law Association is a national NGO and an Ontario legal aid clinic. We were formed in 1970. We assist members of the public in participating in environmental decision-making, and we advocate for better laws to protect against environmental harm.
I have filed a written brief with the clerk of the committee, which I'm sure you'll receive in due course. I want to say, as a preliminary comment, that CELA is a strong supporter of the principles of a circular economy, including the principles of safe material reuse, a reduction in energy utilization and a reduction in discarding materials.
However, there are issues that I'm sure you'll investigate in this committee that I won't be delving into today. We'll probably file a second brief from CELA on issues dealing with, for example, the potential for toxic chemicals and plastics to make their way into reused products.
For today, I want to say that those principles do not apply to used nuclear fuel waste. Nuclear fuel waste is high-level waste under Canada's nuclear fuel safety act. It is the waste that results after uranium fuel has been used. Natural uranium fuel has been used in the CANDU reactors in Canada. It is extremely hazardous after it's been used in the reactor, and it must be kept separated from people and the environment for hundreds of thousands of years, according to the Nuclear Waste Management Organization.
There have, however, been some recent proposals for and even funding toward research in Canada with the idea of “reprocessing” this waste, which means extracting the plutonium from the used fuel waste so that the plutonium can be used as a nuclear power fuel. However, plutonium can be used both as nuclear power fuel and in atomic weapons.
Extracting plutonium from used nuclear waste contradicts Canada's decades-long practice of not allowing the reprocessing of nuclear fuel in Canada. The reason is that it raises concerns about the diversion of that separated plutonium toward atomic weapons use. This is something that is made vastly easier—if you can say that—for bad actors to do once the plutonium has already been separated from the very hazardous used nuclear fuel waste.
That risk exists, regardless of the original intent behind the reprocessing exercise and regardless of how pure or not the extracted plutonium is. That statement has been made by, among others, the U.S. National Academy of Sciences and the United States Department of Energy.
In addition, the reprocessing itself results in other nuclear waste that is even harder to deal with than the current nuclear fuel waste that Canada is already contending with. There's more hazard, and there are additional types of radioactive materials that result. Much of it is in liquid form, and there are no current prospects for the long-term disposal of that reprocessing waste. There are, additionally, examples elsewhere in the world, where reprocessing facilities have resulted in extensive environmental contamination.
The industry advocating the idea of reprocessing nuclear fuel waste has been trying to utilize ideas like waste reduction and recycling to support these proposals, but these completely miss the mark in terms of the nuclear weapons proliferation risks that are raised. Globally recognized non-proliferation experts, such as scientists at Princeton University, have been warning Canada explicitly about the dangers of allowing nuclear fuel reprocessing in Canada.
My organization, CELA, and other civil society colleagues across Canada have been calling on Canada to explicitly ban nuclear fuel reprocessing in Canada as a result of these risks. We recommend to this committee that it make that recommendation as part of its study on a circular economy.
Those are my remarks to start.
Thank you.
