CNSC is proposing to remove non-proliferation safeguards from SRB’s licence

April 13th, 2015

Ontario Power Generation (OPG) runs the Darlington Tritium Removal Facility to reduce the tritium content of heavy water used to moderate CANDU reactors, protecting workers and the environment. This facility produces and stores 1-2 kilograms of pure tritium gas each year. OPG ships around 100 grams of tritium annually to the Chalk River Tritium Laboratory (part of the Canadian Nuclear Laboratories, formerly AECL) whose primary function is to dispense tritium for OPG’s commercial tritium customers. SRB is the main customer, processing 85 grams of tritium in 2013. While 85 grams of tritium sounds like a tiny amount, David Albright and Theodore B. Taylor (“Making Warheads: A Little Tritium Goes a Long Way”, Bulletin of the Atomic Scientists, Jan. 1988) explain that only 2-3 grams of tritium are needed to boost the yield of a nuclear bomb several-fold. SRB processes enough tritium each year to supply 20-30 nuclear weapons.

CNSC is proposing to remove licence conditions for safeguards and non-proliferation from SRB’s licence. No reason is given for the proposal.

TAP finds this proposal bizarre and maintains that Canada must uphold its obligation under the Treaty on the Non-Proliferation of Nuclear Weapons “to accept safeguards… with a view to preventing diversion of nuclear energy from peaceful uses to nuclear weapons or other nuclear explosive devices.”
