Re: Moon is a harsh mistress
"Yeah, launching it into the Sun makes the most sense. Just friggin' obliterate the shit."
Or you can skip the risk of launching nuclear waste and use it as fuel. One nuclear reactor's shit is another reactor's tasty treat. CANDU reactors can run on light water reactor waste. Fast reactors are happy to burn transuranic isotopes that moderated reactors don't handle well. More conceptual reactors like accelerator-aided sub-critical designs can also burn waste isotopes.
You also need to consider the environmentalist angle on this: smash all the nuclear projects! Consider the anti-nuclear track record:
1) US designs a nuclear power plant with an ability to efficiently create fuel; destroy heavier isotopes; process waste to create weapon proliferation-resistant fuel; and produce negligible waste. The IFR gets torpedoed by green opposition under the guise of proliferation risks, leaving hundreds of reactors churning out waste. Fortunately, there was a plan for that.
2) US spends decades scoping out a stable, safe underground waste repository and engineering solutions to contain the waste for thousands of years. Green opposition torpedoes that Yucca mountain repository for fear of nuclear leaks, leaving waste stored in big swimming pools and rusting barrels near cities. That worked well at Fukushima, right?
3) Brilliant group of rocket scientists and nuclear engineers plan to safely remove nuclear waste from Earth and store it on the moon (or fire it into the sun). Green opposition torpedoes this plan under the guise of preventing ozone depletion and global warming by rocket fuel, leaving nuclear fuel once again on Earth.
I recall reading a science fiction book (I think it was "The Vampire Master Race Theory," by Frezza) that had a pearl of wisdom: you can predict the actions of a large organization by assuming it is run by a cabal bent on destroying it. Certainly seems to be the case of the anti-nuclear movement, which has consistently undermined attempts to utilize and safely store nuclear waste and instead left it close to major cities.
