Nonproliferation analysts and reports from the Bulletin of the Atomic Scientists indicate that China has likely resumed the production of weapon-grade highly enriched uranium (HEU) at its historic Emeishan (Plant 814) facility in Sichuan province. High-resolution commercial satellite imagery reveals rapid construction activity and completed processing buildings specifically designated as Emeishan Project 4 (CEP4) signaling a major boost in domestic enrichment capability. Analysts note that China’s accelerating enrichment capacity far exceeds what is required for its civilian commercial nuclear power fleet, closely matching the estimated fissile material requirements needed to support its expanding nuclear weapons stockpile. China officially halted its production of weapon-grade HEU in 1987, relying on existing stockpiles for decades, but the new infrastructure points toward a substantial strategic shift in Beijing’s nuclear posture. Nonproliferation experts emphasize that the lack of public reporting and transparency surrounding these expanded enrichment sites complicates international arms control efforts and deepens strategic friction with Western defense planners.
