Why not just dispose of nuclear waste in the sun?


-The sun is a constant nuclear reaction that's about 330,000 times as massive as Earth; it could swallow the tens of thousands of tons of spent nuclear rods as easily as a forest fire consumes a drop of gasoline .
It is not a good idea to send radioactive waste from earth into space as a disposal method as the cost of the rocket is so large and the risk of an accident during the process is too large. If your goal is a way to spend money to fix the nuclear waste problem, fuel recycling is a much better option. Fuel reprocessing is expensive but it eliminates the vast majority of the waste and decreases the dangerous period from 100,000 years to 1,000 years. At the moment, the current cost of launching stuff into orbit is about $20,000 per kilogram of your payload. That's just to get into orbit, that's not counting the additional fuel kick needed to get your vessel going to the sun. Also, that's not counting the fact we can't really recycle these craft that are getting sent to the sun. One accident trying to launch one of these rockets means you've just splattered a ton of radioactive waste all over the launch facility (or worse, the upper atmosphere). Basically, you've just caused another catastrophy in an entire region or country, depending on the altitude of the explosion, local wind speeds, nuclear payload, etc.All in all, we're better off shooting them into the core of the Earth. Of course, by that, I mean burying it. It's closer, and it's less dangerous. If we're lucky, sometime in the future, someone will work out a way to transmute certain wastes into usable fuel really cheaply, or accelerate the decay of the really nasty stuff so that it won't be radioactive for millions or billions of years.It´s a very complex mission and it could end destroying more the Earth, instead of taking away a part of the waste.This proyect must be studied during a lot of time until obtaining a result without negative consequences.
