nuclear reactor

It's funny that on the day that NBC officially cancels this show, it has one of its best episodes in years.

There's a nuclear mishap in California, and President Bartlet has to figure out what to do about it, as Vinick worries about how he'll look to voters (he's a Senator from California and OK'd the building of the San Andreo reactor), Josh tells Santos to lay low, and the crisis in Kazakhstan gets worse.
