Kool: It is VERY difficult (not impossible, but difficult) to use LFTRs for nuclear weapons production. A byproduct of ordinary use of U-235 (and PU-239), both with U-238 as "filler", is that they produce a nice amount of weapons-grade material in their normal operation, and breeder reactors set up to produce fuel also produce bomb material.
