I have a background with radioactive materials, so I have always been interested in this.
One of the proposals I always found attractive was encasing the radioactive waste in huge bullet shaped casks, and dumping them in the area in the deep south Pacific (It has been years, but it was called something like “The Great Barren Zone” but I can’t remember now)
That area that is vast, generally devoid of many forms of sea life, and covered with an incredibly deep layer in deep water of some primordial ooze. I think it contains “Point Nemo” which is the furthest distance one can get from land anywhere on earth. It is also the earth’s largest geologically inert area.
They did some tests and when they sent some tests down in the hydrodynamically streamlined caskets, they picked up so much velocity it apparently buried itself so deeply in the ooze and sealed itself up afterwards, and the ooze was nearly electrostatic in its “clinginess” that the caskets became encased.
I thought that was a damn good idea.
I wonder how much oil remains onboard the Arizona.
If you visit the memorial, take note of the “tears of the Arizona” drips of black oil coming to the surface.
It’s an excellent idea. I’ve read, and it makes sense, that any radioactive waste that leaks out would be diluted to the point of being not even negligible.
