This is an exploit, there is no argument. You are creating an infinite resource loop, producing uranium and other stuff out of only uranium, forever, with no input. Especially since uranium is meant to be non-renewable.
No this is not 0 input! You'll need good start up mats and setup before you can even produces uranium in a mass scale, some time, energy, and tin to even just to "converts" the uranium. So yea it's requires some things to do it so in the end, I still don't think it's an exploit. Bees do it even cheaper for even less time for a small reactor plant for the same thing. So annoying that people are calling things exploits even though you need inputs to do it. From HP boilers looping, Dartcraft Force engines power looping, Mining lasers, and this. Good thing I'm going behind my own wheels and I can leave these other servers that tries to "burns down" these "exploits" to dusts! So yea people can have their opinions but "0 inputs" is where I'm not going to put up with! Like seriously technically solar panels to matterfab+recyclers= more solar panels is more an "exploit" than this time consuming process. Now those panels require no maintenance and ho can't blow up! So yea your argument of nothing but "air" is needed is false. Really make the game stale when all these "exploits" are removed. Yep there are exploits but this is not like duping items in bags or RP2 retrievers duping or the ic2 pump lava dupe. Those things are 0 inputs or ridiculously cheap. If I had to chose bees or this to be exploit then I would say bees. (don't remember them eating tin cells to make the uranium or take 7 or so hours to complete a reaction cycle) Oh and I hate servers that do one thing and does the opposite like having mining lasers disabled and having mass fabs enabled with GT on.
