How small are modular reactors?

They can be as small as a three-storey building ...or as large as an entire city block.

That's the equivalent of a mid-size shopping mall!

Regardless of their size, the major parts of SMRs will be housed within a larger facility.

This is where you will find systems that support safe operation and maintenance, harness heat, which can do useful things like generate electricity.

We have been preparing to regulate SMR projects for many years.

Anyone who wants to build and operate an SMR facility needs to meet our requirements for safety, security, environmental protection, Canada's commitments to nuclear non-proliferation.

Big or small and no matter the technology, it's the CNSC's role to regulate the nuclear industry and protect the health and safety of the public and the environment.
