NRC Approves Safe Nuclear Plant Closure Plan Changes

Published Date: 12/12/2025

Notice

Summary

The Omaha Public Power District wants to update its plan for closing the Fort Calhoun nuclear plant in Nebraska. The Nuclear Regulatory Commission reviewed the changes and found they won’t harm the environment, so the site can be safely released for other uses. This means the cleanup can move forward without delays or extra costs.

Analyzed Economic Effects

3 provisions identified: 3 benefits, 0 costs, 0 mixed.

Site cleared for unrestricted reuse

The NRC issued a Finding of No Significant Impact for OPPD's License Termination Plan Revision 2 for Fort Calhoun Station, allowing the license to be terminated and the site to be released for unrestricted use. The EA and FONSI are available on December 12, 2025, and the change applies to the Fort Calhoun site in Washington County, Nebraska.

Grout used to limit groundwater release

The proposed action includes using grout in excavated trenches and subsurface concrete structures deeper than 3 meters (9.8 ft) to prevent groundwater in-leakage and limit radioisotope diffusion into site groundwater. The NRC staff concluded this grouting, with backfill of clean material as described in the LTP, would limit impacts to water resources.

Dose methods meet NRC safety rules

The license amendment revises dose calculations and final site survey methods for concrete structures deeper than 3 meters (9.8 ft) in the Auxiliary Building basement and portions of the Containment Building. The NRC found the revised dose calculations demonstrate the site would meet applicable radiation protection requirements in 10 CFR part 20 and concluded there would be no significant radiological impacts to public or occupational health.
