Esfahan Nuclear Technology Center/Research Reactors
According to the IAEA, Iran has a light water sub-critical reactor (LWSCR) that uses uranium metal fuel. The reactor operates only a few days per year. The Miniaturized Neutron Source Reactor (MNSR) is a research reactor of Chinese origin. The MNSR has been in operation since the mid-1990s and has a lifetime supply of one kilogram of 90.2 percent enriched fuel. The Heavy Water Zero Power Reactor, supplied by China, went critical in 1995. There is also a decommissioned graphite sub-critical reactor (GSCR) which used uranium metal fuel.
