The entire premise is an exercise in fear mongering, not aimed at people 10,000 years in the future but rather at people in the present. The message is that we must not use nuclear power because the waste is so dangerous that we have to go to elaborate theatrical lengths to prevent cave men in the future from killing themselves with it. The most sensible way to deal with the waste, after burning up transuranic waste in nuclear reactors (common sense), is to put it somewhere that the effort to find and retrieve it is so great that only people who already knew what they were doing could manage to get their hands on it. The most obvious candidates for such a method are dumping it into the ocean. If you want to get fancy it could first be dissolved into water, or instead vitrified and sealed. Either way, it could be placed directly on the sea floor in deep parts of the ocean, or dropped into subduction zones, or buried beneath the sea floor. Any of these would be adequate. Another option is horizontal boreholes a few kilometers deep, but that's a bit less practical. Of course people today lose their lids at the thought of a little tritium getting dumped into the ocean; this is the result of the same sort fear mongering campaigns that "this is not a place of honor" comes from. But this is a sociological problem deliberately created by activists, not a technological problem. A great deal of nuclear waste, including spent fuel and reactor components, was dumped into the ocean in the 20th century and nobody crying about Japan's tritium loses much sleep over that waste. China pretends that Japan's tritium will ruin fish for China, but they're not acting concerned about the several hundred TBq of nuclear waste the Soviet Union dumped into the Sea of Japan. Their objections to Japan dumping their tritium are political theater. The impact this oceanic dumping has had since it was done decades ago can be studied, and the answer is that it's not an issue. Water is a really great shielding material and very deep water is really good at keeping meddling idiots away from things. Much better than any spooky monument or deliberately poisoned land. https://en.wikipedia.org/wiki/Ocean_disposal_of_radioactive_waste https://en.wikipedia.org/wiki/Ocean_disposal_of_radioactive_...
