Evidence detail

Target: permission issued, Q1 2027

Construction permit expected in the first quarter of 2027 (18-month NRC review)

A stated target, not something that has happened. It does not set a state. Targets can move; earlier and later ones are both kept.

“a wholly owned subsidiary of Dow, filed a Construction Permit Application (“CPA”) with the NRC in March 2025 which was docketed in May 2025 for an 18-month review period with an expected review completion by late 2026 and receipt of the CPA expected in the first quarter of 2027.”
