The NSDF application to the CNSC
We’re the Canadian Nuclear
Safety Commission, Canada’s nuclear regulator.
Our staff are
reviewing the application from Canadian Nuclear Laboratories to build a
Near Surface Disposal Facility (NSDF) in Chalk River, Ontario.
does “near surface disposal” mean?
An NSDF is a type of
waste facility where radioactive waste is stored at or below the
In order to prevent contaminants from
getting into the surrounding environment, the waste is placed in vaults or
cells, with a special bottom liner.
This project would include 10
storage cells. When a cell is full, a cover will be placed on top to seal
the waste and protect it from contact with people, animals and weather.
Protecting our water
We know there are concerns about the
proposed Near Surface Disposal Facility affecting the Ottawa River.
That’s why over 50 specialized scientific and technical experts,
like geoscientists and structural engineers, at the CNSC and across
government are carefully reviewing every detail of CNL’s application,
taking into account international best practices.

protecting people and the environment:
protective materials planned for the facility, to ensure that the liner and
cover systems contain and isolate the waste.
water flows to ensure the impact on the Ottawa River would be negligible if
small amounts of contaminants ever travelled to the river, both during
operation and after the facility is shut down.

Like you, we want to protect the environment, so we all
have clean water, air and soil — now and for future generations.
