For <nuclear weapons> you need a certain level of <isotope> purity of either <plutonium-239> or <uranium-235>.

And the easiest way by far to achieve this purity is to produce <plutonium-239> in a <breeder reactor>, which allows you to get it out with much cheaper chemical processes rather than costly <isotope separation> methods.
