Twenty seven of 104 NRC status reactors are below 100%, and 15 are at zero power. What happened to supposedly 24/7 nuclear power?

Fifteen are at zero power: Calvert Cliffs 2, Crystal River 3, Diablo Canyon 2, Fort Calhoun, Hatch 1, Hatch 2, La Salle 2, McGuire 1, River Bend 1, San Onofre 2, San Onofre 3, South Texas 2, Turkey Point 3, Turkey Point 4, and Wolf Creek 1.
