The Heping Uranium Enrichment Plant is China's second gaseous diffusion facility (GDP). It is one of the so-called “Third Line” facilities, built in the inner Sichuan province as a backup to what was perceived as the more vulnerable Lanzhou gaseous diffusion plant. [1] Heping uses gaseous diffusion technology similar to that used at Lanzhou, although it reportedly has a larger production capacity.

The plant became operational around 1975, but was converted to civilian use in 1987 as part of China’s “military-to-civilian conversion” policy. [2] During this period of military production, the Heping GDP is estimated to have produced 2.7 million SWU, enough for 14 tons of highly enriched uranium (HEU) total. [3] The plant is reported to be operational, although in the late 1990s China indicated that its ageing gaseous diffusion plants would be replaced by gas centrifuge plants for commercial production of low-enriched uranium (LEU).
