  Which is why your suggestion of simply recycling copper won’t work. You don’t have copper, you have a radioactive alloy.

    Not after 50 or so years. Then it’s just non-radioactive copper.

      That’s not how radioactive half lives work.

      Learn about radioactive decay and what half life means.

      A half life of 100 years many that after 100 years half of it is copper while the other half is still nickel 63. It does NOT mean that after half that time all of it will be copper
