How can that be? Why are nuclear plants unable to produce?

Aren't they baseload plants and run at pretty much the same capacity most of the time?

In one of four nuclear plants in Texas, "According to the Nuclear Regulatory Commission, the shutdown of the nuclear reactor was caused by a disruption in a feedwater pump to the reactor, and that caused the plant to trip automatically and shut down early Monday."

Maybe the plants themselves are having issues with equipment freezing?

Correct. Nuclear still requires water, and the water pumps/pipes are freezing because they weren’t properly weatherized.
