Nuclear waste is mostly solid and very dense. Water absorbs almost all harmful radiation within a few meters The thought process behind just throwing barrels into an ocean trench as was done by the US was and still is sound but people are freaked out by the notion. The UK was encasing barrels in concrete before doing the same which is more than good enough by most measures. Ultimately nuclear waste is easier to deal with than some other toxic industrial waste or chemicals.
