Pyongsan Uranium Concentrate Plant (Nam-chon Chemical Complex): Infrastructure Development and Status

Nuclear Weapons
, by , and The Pyongsan Uranium Concentrate Plant represents a critical component of North Korea’s nuclear research and weapons development programs. Through analysis of 100+ medium- and high-resolution declassified and commercial satellite images, this report aims to provide a new and unique look into the facility. It is also the second publication in a series analyzing North Korea’s uranium concentrate plants as well as one of the most comprehensive collections of unclassified information and satellite imagery presently available of the Pyongsan facility.

Pyongsan Uranium Concentrate Plant (Nam-chon Chemical Complex)

Nuclear Weapons
, by and The Pyongsan Uranium Concentrate Plant (38.318369 N, 126.432360 E) is located in Pyongsan-gun (평산군, Pyongsan County), Hwangbuk-do (황북, North Hwanghae Province), approximately 45 kilometers from the DMZ and 96 kilometers northwest of Seoul—the capital of South Korea. Since approximately 1990 it has occupied an critical role in the Democratic People’s Republic of Korea’s (North Korea) nuclear research and weapons programs as the sole known provider of uranium oxide (yellowcake) to these programs for fuel fabrication or enrichment.

Pakchon Uranium Concentrate Pilot Plant

Analysis, Nuclear Weapons
, by and The Pakchon Uranium Concentrate Pilot Plant is one of only two declared and known uranium concentrate plants in North Korea (Pyongsan Uranium Concentrate Plant at Pyongsan is the other). This facility was used for Yellowcake production at least through the mid-1990s, and therefore would require inspection under any new U.S.-DPRK denuclearization declaration and agreement as it has not been subject to international inspection for over 25 years since IAEA visits to the site as part of the Full Scope Safeguards Agreement process in 1992.
