Their activities include: A: Enriching uranium to weapons grade. B: Testing a neutron detonator and implosion system (chemical explosive lens). As a result of research at the facility, a test was done out of Iran’s Parchin military site several months ago. After the revelation of the high-explosives experiment activity, Iran started to clean up the site and continues to stonewall the IAEA’s request to inspect the Parchin site. C: Designing and building a nuclear warhead to arm Iran’s Shahab 3 ballistic missile. D: Separating plutonium for a plutonium implosion-type fission bomb. Iran’s heavy-water reactor near the city of Arak is nearing completion and is capable of providing spent fuel that, once processed, could produce plutonium for nuclear bombs. The separation of plutonium from fuel is an easy process requiring dual-use off-the-shelf equipment that Iran has already purchased. The source indicated Fakhrizadeh-Mahabadi’s atomic warhead project seeks to build three nuclear warheads in its initial phase. Tests of the implosion system and neutron generator have been successful, the source said, and the design of the nuclear warhead is nearly complete.
