"442 nuclear powerplants worldwide"

 
I was wathching Fox News tonight and it said there were 442 nuclear powerplants worldwide.  I just about fell off my chair so I googled it. and sure enough this is what I copied off a site:

As of Jan 19, 2011 in 30 countries 442 nuclear power plant units with an installed electric net capacity of about 375 GW are in operation and 65 plants with an installed capacity of 63 GW are in 16 countries under construction.
