Are u still sane? U propose contaminating the entire ocean for millions of years with radioactive wastes?
Several nuclear submarines (with tons of fuel) have sunk to the bottom and the entire ocean is not contaminated. 15 feet of water in a swimming pool is enough to make anything outside that distance safe. The radioactive atoms mostly came out of the environment, diffuse ores in the ground, where they have been sitting safely for eons. Putting those waste atoms into cubic miles of water dilutes them back to the frequency those atoms had as ore. Plus we can burrow the canisters into currently stable sea bed and not too much more cost over just dumping and letting gravity settle the casks. Additionally, the “entire ocean” contains plenty of naturally occurring radioactive atoms that have weathered off the land over time, and the ecosystem has managed to live with it.
