Then you're in the wrong country, mate. If you indeed have a sound project proposal and care more about the realisation of the project than the money then Chinese are the ones you should be proposing it to.
This is purely commercial venture stuff with existing proven technology lol. How Chinese decide to integrate into any programs they do is up to them hehe. I doubt India would have much issue either....but both have signed environmental agreements for LEO and mid orbits too iirc....not sure about GEO, but probably it has been regulated there too.
Even in NASA, they have used it when absolutely needed to and the location is far from Earth mission wise (Mars Science Lab comes to mind) in recent years. Just off limits to commercial "for-profit" products pretty much, especially for anything that orbits and can fall back on Earth.
That basically makes the market very stagnant and no development through competition can take place. There are pros and cons with each side of this issue. Chernobyl really had a huge impact on the industry in general basically....and its not all propaganda (though a lot of it is)....because these isotopes in question are pretty nasty stuff to biology in general.
When it comes to fusion however, it becomes an interesting story given no radioactive products or fuel are created/used. But the technology is in its infancy still and will need much development.
A derivative of this is plasma propulsion (a higher thrust version of ion propulsion) You can read up on VASIMR program if you would like.
For aircraft it becomes much more straightforward. Fission is out of the question given the weight involved with shielding. For fusion I remember having a long discussion with another professional in another forum long time back about the potential....we both agreed that it will probably be more likely that we will first see large scale electric propulsion (with batteries/wireless transmission) given the weight penalties involved even here (once we have even worked out how to make fusion work sustainably in the first place)....unless lockheed really has stumbled onto/developed something game changing regarding weight/size like they are claiming (but I feel is unlikely and is more for PR purposes etc.)
