It's not a matter of "some development in the future". We know how to do it now--the obstacles are political. The problem is a reactor + fuel recycling plant look an awful lot like a weapons grade plutonium production plant. People see that word "plutonium" and get scared.
The reality is nobody uses power reactor for making bombs. The desired reaction is U-238 + n -> U-239, decay to Np-239, decay to Pu-239. However, if you leave the fuel in for too long you get an increasing amount of Pu-239 + n -> Pu-240. Pu-240 is a neutron emitter that gives bombmakers big headaches. If someone were to make off with a load of plutonium from a reprocessor they're going to have a hard time turning it into a working bomb.
However, there's another approach to avoiding theft: Most of these isotopes don't matter. The fuel is "spent" because of a few neutron absorbers. Remove those, don't clean up the rest of it. Leave stuff like that Ba-133. The resulting fuel works just as well but unlike fresh fuel it's very nasty to deal with. The industry will have no problem with it--it's no nastier than the rods were when they came out, they have the machinery to handle it safely. The thief doesn't. You're not walking out with a gamma emitter in your pocket without setting off a bunch of alarms and if you try to steal much it will kill you before you manage to make off with it.
There still is one political headache, though--a reprocessor plant + a reactor built for quick fuel changes is the heart of a plutonium bomb program. It's hard to say we can have such plants but places like Iran can't.
