Yes, sorry for not having done so. Edited my comment.

On reactors under construction, IAEA's PRIS database. https://pris.iaea.org/pris/worldstatistics/underconstruction...

On planned reactors, World Nuclear Association. https://world-nuclear.org/information-library/current-and-fu...

EDIT: wrong link for IAEA's db.

What matters is how many will be completed, not cancelled. That number is rather smaller.
