I made this because I didn't have a simple Kovarex blueprint. I'm sure there are better blueprints out there, but I made this one in the hope that it would serve as a tutorial for circuits. It uses a buffer of 238 in the belt and rotates round and round. It is designed to work to a certain extent even if uranium is put in by hand. However, be sure to drain the uranium-235. This blueprint does not manage 235. We hope this will be a stepping stone to the design of spacecraft, the key component of the space age.
