The Canadian Nuclear Safety Commission (CNSC) is to conduct pre-licensing vendor design reviews (VDRs) of small modular reactor designs from NuScale Power and Westinghouse Electric Company.
The reviews of the NuScale SMR and Westinghouse’s eVinci micro reactor will incorporate the first two phases of the VDR process.

The three phases of the VDR process involve a pre-licensing assessment of compliance with regulatory requirements; an assessment of any potential fundamental barriers to licensing; and a follow-up phase allowing the vendor to respond to findings from the second phase.
A power plant could include up to 12 power modules, each 25 metres in length, 4.6m in diameter and weighing around 450 tonnes.
It intends to apply for generic design assessment in the UK.
Westinghouse is developing the eVinci micro reactor as a small nuclear energy generator for decentralised generation markets, such as remote communities, or arctic mines.
The company says the reactor design is a combination of nuclear fission, space reactor technologies and over 50 years of commercial nuclear systems design, engineering and innovation.
The reactor has a solid core, built around a solid steel monolith with channels for fuel pellets and heat pipes that remove heat from the core, and has minimal moving parts.
