Loads. It has a volume of 2.8 billion cubic kilometres. At 0.0000033 g 
uranium per kilogram of water, that is 180 million kilograms of uranium. 
That is still 1.3 million kilograms of uranium 235 if you just count 
that. Any human reactor, even if dumped straight in, is insignificant 
compared to this.

The issue is mixing. You don't want a lot of active isotopes near your 
coast and your fisheries.
