Same thing happened with the Rancho Seco plant (a couple miles from where I grew up), though at least that was somewhat justified, given that it had "a long record of multiple annual shut-downs, cost over-runs, mismanagement, multiple accidents that included radioactive steam releases, restarts after unresolved automatic shut-downs, and regular rate increases that included a 92% increase over one three-year span" (Wikipedia's words).

It's a shame that it had to be decommissioned entirely, though. I would've been okay with fixing it up. Alas, all that's left are the cooling towers; all the power generating equipment's long gone, so it'd probably be pointless to try to do anything with it now. It'll just have to loom ominously on the horizon. There's solar and natural gas generation there now, though, which is pretty neat, I guess.
