Nuclear Fleet Outage History

Every shutdown recorded for 107 US power reactors since 1999 — 4402 in all, through 2026-09-04. Durations are the first to the last calendar day on which a unit reported zero reactor power, reconstructed from the NRC's daily Power Reactor Status Report. Each shutdown carries the basis for how it was classified and, where one exists, a link to the NRC filing behind it. Data is constantly being added and refined; errors may exist.
