Thank you for clearing up the question about removing the old already there.  And thank you on the atomic waste question, however, I was referring to the atomic waste buried on a some small Pacific island. The responsibility of the inventor, should have included it's disposal.   Which I guess explains why the inventor of the bomb was so troubled!  The removal of the old telescopes should tell us how well the builders will do.  Right now, the only thing to dispose of at this stage is the paper it's drawn upon.
