This infographic shows the origin of nuclear reactors under construction across the world. Almost a third of all new projects is implemented by Russia’s Rosatom corporation.

This is definitely wrong. For example, I know Canada has reactors under construction: https://news.ontario.ca/en/release/1002543/ontario-breaks-ground-on-world-leading-small-modular-reactor
They haven't started construction of that reactor in the article you're referencing from 2022, they are talking about site preparations for construction of the reactor, early construction basically, not even sure if that counts for the Wiki page they sourced, if they have begun by now it might not be reflected in this https://wiki.froth.zone/wiki/Category:Nuclear_power_stations_with_reactors_under_construction?lang=en as Statista lists many more Chinese projects than Wikipedia does.
When they do /if they did begin working on the actual reactor, it's projected to have 1/3 (?) the output of a regular commercial nuclear reactor, so I leave it to you to argue for its inclusion on Wikipedia.
