DPRK Nuclear Inventory & Fissile Stockpile Workbench

Fissile Production & Pit Modeling ACTIVE PROJECTION

Stated Warhead Citation 57

Pu-239 Weapon-Grade Stock (kg) 45 kg

HEU (90% U-235) Stock (kg) 1200 kg

Composite Core Fraction (Pu Pit + HEU) 65%

Plutonium Per Pit / Core (kg) 4.0 kg

HEU Per Warhead (kg) 20.0 kg

Reactor Status (Yongbyon 5MW + ELWR)

Scientific Context: Trump's citation of 57 nuclear weapons aligns with median fissile material throughput models. Highly enriched uranium cascades at Kangson and Yongbyon yield ~80 kg/yr while Yongbyon 5MW(e) and ELWR yield ~4–6 kg/yr weapon-grade Pu.
