The Canadian Nuclear Laboratories Whiteshell Laboratories Restoration Project on Wednesday.

Its nuclear reactor was built for research, not electricity generation. At its peak, experts from across the globe visited the scientific hub.

The reactor shuttered in 1985 after being used for research on power reactors and testing coolants, among other things. Waste storage and small modular reactor research also occurred on site.

The site has been closing, piece by piece, since the late 1990s. The process is expected to finish in the 2030s.

Canadian Nuclear Laboratories — the private firm licensed to oversee and decommission the site — invited the Free Press to tour its facilities this week.

Post-decommissioning, most of the 11,000 acres — 99.5 per cent — will be reusable, according to Canadian Nuclear Laboratories, the private company overseeing the decommissioning.
