Gen 4 reactors will happily run in a way that it effectively reprocesses its own waste. It's also got passive safety and the resulting waste (which at this point really isn't fuel) has a half-life well short of the hundred years.

They are also fictional. We'll be able to judge how well they operate and how they reprocess own waste when we see one operating safely for some time.

No, it is not fuel. Part of it may become fuel if one is allowed to reprocess it. Reprocessing, however, is a very tightly regulated business, and in many places, for example in the US, or in Japan, or in Russia it is not an option, or not a very important option. Do you know why it isn't a wide-spread, happy industry? Yep, because it is expensive as hell, dangerous and dual-use.

Here's a fun experiment to do: stop pretending you carry a cesium source and a Geiger counter, and consider what should be done with the 1000+ tons of highly radioactive mud that is already collected on-site in Fukushima. Right next to the used fuel pool.

Please make it a rational solution that can guarantee no leaks for a few hundred years and doesn't cost a brazillion billion million yen.

One, you have serious reading comprehension issues. OP claims coal produces more nuclear waste than nuclear power.

Two, that SA article has been debunked so many times, it isn't even funny. The 'research' it is based on is from 1977 and it discusses coal plants that aren't built anymore. Here, for your reading pleasure:

Even this claim sounds quite far-fetched to me.

What certainly played significant role in bringing down the Republic was the inability of the Romans to adapt their political system, which was quite efficient in running a city-state (or a loose union of several city-states), to govern the huge country their successful military campaigns created. It simply didn't scale well enough.

Another big hurdle, IIRC, was the impossibility of legal reform because the Roman viewed the laws of their forefathers as sacred. The legal mess they got on their hands in the last years of the Republic allowed all kinds of manipulation of the political system -- something which Caesar and his successors used skillfully to gradually take over.

I don't think we have enough facts to ascertain the role of the concrete in this process, though.

A large number of installed systems work by fiat. That is, they work by being declared to work. -- Anatol Holt
