Isn't X-10 the world's second nuclear reactor? https://en.wikipedia.org/wiki/X-10_Graphite_Reactor

The X-10 Graphite Reactor at Oak Ridge National Laboratory in Oak Ridge, Tennessee, formerly known as the Clinton Pile and X-10 Pile, was the world's second artificial nuclear reactor (after Enrico Fermi's Chicago Pile-1), and the first designed and built for continuous operation. It was built during World War II as part of the Manhattan Project.

My grandpa is a retired nuclear physicist.

He suggested that Pile-1 could've been made permanent if they'd wanted to; not sure if that's true.

He worked at Chalk River in Canada. Have you heard of it? Have you ever been there?
