Iran has been secretively using this reactor to organize such functions that likely connected Iran’s attempts to develop nuclear weapons.&nbsp. It is clear that without informing the IAEA Iran irradiated uranium oxide (UO2) limits in the TRR and shifted plutonium in glove boxes at Tehran Nuclear Research Center (TNRC) laboratories.&nbsp. Iran had also agreed that it developed a minor quantity of polonium-210 in the TRR in the early 1990s via the irradiation of bismuth limits.&nbsp. Polonium 210 is a popular radioactive stuff employed in a beryllium-polonium neutron initiator, which begins a series of reactions in a nuclear weapon (Teheran Nuclear Research Center par. 7-8).
