That thing potentially wastes tons of lithium and perhaps beryllium (both are rare and valuable metals).

Last time I checked lithium and beryllium are easier to come by than U235.
Forget the isotope, Li is a couple orders of magnitude more abundant than natural U; Be a couple multiples more abundant than natural U.

Sure there isn't online removal of the fission products from solid fuel. However, if you have a short irradiation cycle and reprocessing you can do it. ....
The point is not solely what is technically possible, but what also what is economically plausible. The major advantage of high fuel burnup *in place* is cost reduction. Adding a loop where, the fuel is removed from containment, shipped off for dis-assembly, is reprocessed, reassembled and reinserted into the reactor can not be remotely as cost effective.

Even more so.
