If the waste is so dangerous that you would want to store it in the bedrock of the Canadian Shield free from running water than you can not say it is not pollution no matter how far it is refined.
Shooting it into the Sun, first you have to get it off the planet, rockets explode and you would have produced, at the least, a very large dirty bomb and exploded it in the atmosphere. Worst case scenario CRITICAL MASS.
No, absolutely not, not yesterday today or any day in the foreseeable future. There is not much difference between power plant fuel and weapons grade, once you have created this stuff you can't uncreate it using it. The USSR was trusted with its fissionable material, yes we were worried about them throwing some our way but not about the security of it. Well less than 2 decades later the USSR collapsed into several smaller Nuclear States and huge amounts of weapons grade material has gone missing.
This stuff has a very long shelf life, will the USA still be here thousands of years from now, our bombs will be.
My opinion is we should drill a side shaft into a volcano's magma pot and after serious efforts to dilute this crap we inject it into the magma, all of it. This is Pandora's Box and we should put the lid back on before even hope gets out.
Hydrogen is the most common, basic element in the Universe, I'm no fan of a hydrogen economy but it would be far better than a nuclear solution.
Solar, hydro, hydro thermal, cellulosic biomass, algal biomass, wind, Tidal... The list of cheap/free energy that pollutes very little or not at all is extensive and provides us with to many alternatives to suffer the consequences of nuclear power. The reason why this is being shoved on us is because control of the power stays in the hands of a few the same as it is today, POWER=MONEY=POWER.
The answer to this and over population is to reinvest in our space program which hasn't seen any real progress in decades, mostly do to lack of funding.
I think your approach to nuclear energy generation displays a lack of confidence in the ability of man to innovate.
Renewables are unlikely to fulfil the energy needs of an ever more power hungry global population, and pursuing things like windmills is an expensive and ultimately fruitless exercise.
Oil and gas supplies are finite, and are becoming ever more difficult to extract in a commecially viable way.
Regressing to the energy needs of the middle ages is not, as the Greens would like to have you think, the way to go.
So what are we left with? Nuclear.

For nuclear power, the current generation of once-through light water reactors were never seen as an end point for nuclear energy, but only a beginning. We are currently using the inefficient Newcomen engines of the nuclear age, but have yet to deploy the greatly improved equivalent of the Watt engine. The Watt engines of the nuclear age will likely be generation-IV fast reactors, possibly accelerator-driven machines or even fusion-fission hybrids, each of which can improve fuel burn from less than one per cent to greater than 99 per cent, while incinerating the spent fuel (wrongly classified as waste) from our current fleet of reactors. This will create yet more energy and extend the useful life of uranium deposits into the far future. Even more important for the future will be the use of thorium as a fertile and abundant fuel which will enable nuclear energy to be generated in copious quantities for quite literally thousands of years to come.
Let’s be clear: there is no shortage of high-grade energy, only a shortage of ambition in some quarters and a retreat from the idea of human progress through technical innovation. That doesn’t mean there are no technical problems to overcome – for example, there are serious engineering challenges in building really big nuclear plants – but there are some startling ideas now being discussed about how these problems could be solved.
Whatever technologies are ultimately devised and deployed, our goal must be to generate yet more clean, low-cost energy. We will need this energy to power the developing world, deliver rapid transportation, process and store information, light our growing cities, explore new intellectual horizons in science and recycle strategic materials in ways undreamt of by today’s greens.
