Omaha Public Power District closed the single-unit Fort Calhoun PWR in October 2016 for economic reasons and switched from SAFSTOR to prompt DECON in 2019. Release of the bulk of the site (except the dry-cask pad) is expected in 2026, with an LTP revision under NRC review.

Notes
Capacity 482 MWe per WNA. NRC estimated closure 2026 refers to release of the bulk of the site; ISFSI decommissioning planned 2059. Cost = remaining DCE in 2025 dollars ($52.9m license termination + $5.9m site restoration + $323.4m spent fuel management); the 2018 SAFSTOR-based DCE was $1.21bn.
