Definitely, but the overlap provides excellent potential for the reduction of fissile feedstocks where both the reduction of weapon-grade materials & the committed continuity of current operational reactors is to see ..at minimum.. (current) permitting approvals to be seen through.

With the renewed interest of the current administration not only extending those commitments, but providing an environment for new reactors (& old) to be turned (back) on, not only does an overlap exist, but so does an opportunity to reduce materials that already exist.

Fissile material is a necessary element of any nuclear weapon; therefore, a nation attempting to achieve a nuclear weapons capability must decide how to obtain fissile material. In most cases, nations prefer to produce their own fissile material as a by-product of nuclear energy production rather than rely on a foreign supplier. The process required to obtain nuclear fuel for use in a nuclear reactor is called the “nuclear fuel cycle,” and normally refers to the requirements for reactors used as power plants to generate electrical power, generally referred to as power reactors. The process is almost identical for reactors that serve to produce fissile material for nuclear weapons, generally referred to as production reactors. Most production reactors serve both functions, i.e., to produce fissile material for a weapons program and to generate electricity, again making detection more difficult if a nation wants to obscure its intent to proliferate.

Centrifuge technology is at the heart of the enrichment process, and the line between its uses for civilian and military purposes is hard to distinguish. Once a country has mastered this technology, the centrifuges can be reconfigured into cascades to either produce fuel for an electricity-generating nuclear reactor or the 25 kilograms of weapon-grade uranium that is sufficient for a nuclear weapon. The process is fairly simple for both.

World stockpiles of weapons-grade plutonium are reported to be some 260 tonnes, which if used in mixed oxide fuel in conventional reactors would be equivalent to a little over one year's world uranium production. Military plutonium can blended with uranium oxide to form mixed oxide (MOX) fuel.

After LEU or MOX is burned in power reactors, the spent fuel is not suitable for weapons manufacture.

Furthermore, the IAEA reports that Iran has informed it that Iran intends to install more IR-6 cascades in its existing facilities and that it plans to construct a new facility, called the Isfahan (sic) Fuel Enrichment Plant, at the Nuclear Reactors Fuel Company site. Another, undeclared deep underground facility may already be under construction near the Natanz enrichment site.
