ESP
Early Site Permit
An Early Site Permit (ESP) from the NRC approves a site for future nuclear plant construction under 10 CFR Part 52, valid up to 20 years.
ESPs evaluate site suitability for safety, environmental, and seismic factors without committing to a specific reactor design. Issued for six sites including Vogtle and Clinton. They streamline subsequent COL applications by pre-resolving site issues.
Why it matters now
ESP renewals in 2025-2026 support greenfield SMR sites for hyperscale data centers, aligning with accelerated licensing.
