Use unmanned shuttles to ferry loads to a space station and then send a big barge type shipload to the SUN. Price for disposal should be deposited before commissioning of reactor or military use.
Can I have my check now please?
You aren’t the first person to suggest that. Problem is, it takes a lot of rocket fuel to lift a little weight into outer space. The cost of doing this would quickly make nuclear energy a highly unprofitable (economy wrecking) enterprise. Even if you solve that problem, there’s the risk of a shuttle full of nuclear waste exploding in the upper atmosphere. That doesn’t sound like a good thing, does it? Considering the tonnage of waste we’re talking about, there would be so many missions involved that the risk of a catastrophe is more of “when” isssue than a “what if” issue. Oh, and we can’t even manage to put a man on the moon again let alone put thousands of tons of nuclear waste on the surface of the sun. Long story short, no check for you.
