Yongbyon Declassified Part V: Expansion Begins Across the Kuryong-gang

Nuclear Weapons
September 25, 2019, by — Collected eleven months after the image provided in Part 4 (December 10, 1967) this November 21, 1968 KH-4B image of the Yongbyon Nuclear Research Center does not show any significant developments in the operations (with the IRT-2000 research reactor), support or administrative/laboratory areas. It does, however, show continuing development within the village of Sang-dong and the early stages of construction for a new road bridge across the Kuryong-gang in the Pungang-ni area that will connect the support area to the opposite side of the river. Taken as a whole, these developments represent both continuation of a first-phase construction project for the facility and the earliest infrastructure development stages within a longer-term plan for future expansion.

Pakchon Uranium Concentrate Pilot Plant

Analysis, Nuclear Weapons
August 21, 2019, 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.
