First, salt water is very corrosive and subduction on scalle of millions of 
years don't solve the rusting problems in tens of years.

Second, given water viscosity (hydrodynamics drag) and archimedian push, the 
impact speed is not sufficient to entomb  the barrels (furtunately, because a 
sufficient speed would broke the containers!).

Third, ocean botton is not a desert, billions of small worms are here, they 
are the start of a chain food who go up to all the sea domain, many fission 
products are concentrated by biological activity and that is the big problem 
with sea dump.

Sorry, there is no good solution to nuclear energy on Earth, the best we can 
do with fission is to forget it.
