The Hanzhong Enrichment Facility in Shanxi province is China’s largest commercial uranium enrichment facility. In 1992, China and Russia signed a government-to-government agreement for the supply of gas centrifuge plants to produce low enriched uranium (LEU) for use in China’s civilian nuclear power industry.[1] Phases One and Two were located at Hanzhong: the first was completed in 1996 with a capacity of 200,000 SWU/year, and the second in 1998 with a capacity of 300,000 SWU/year.[2] After deciding to site the third phase in Lanzhou, China and Russia agreed in 2008 to construct a fourth phase with an additional 500,000 SWU/year at Hanzhong, for a total of 1 million SWU/year at the site.[3]

All three phases at Hanzhong rely primarily on 6th generation Russian centrifuge technology.[4] The first two phases were placed under IAEA safeguards as part of a Tripartite Safeguards Agreement between the IAEA, Russia’s Minatom, and the China Atomic Energy Authority (CAEA) in order to develop a method for safeguarding Russian centrifuge plants.[5]
