> Chernobyl design was never in use in the US

Commercially. Several early test reactors were essentially just graphite moderated piles not unlike Chernobyl, but they were abandoned for a reason.

Graphite moderated reactors are broadly fine, the problem was with some technical specifics of that specific reactor design, and the operational culture that surrounded it. After Chernobyl, those flaws were corrected and operation of other RBMK reactors has continued to this very day, with no repeats.

		That's good additional clarification, I only meant to point out that graphite moderated, water cooled reactors had existed in the US and UK.
