EPURE

Intelligence Summary: EPURE

Node Identity: EPURE is a weapons categorized under "Weapons Lab" in the france intelligence graph. Hydrodynamic radiography facility at Valduc using plutonium in sub-critical quantities to study material behavior under explosive compression, shared with UK under TEUTATES Treaty.

Research Evidence: The following findings from 5 research documents reference this entity:

1. Confidence: ESTABLISHED --- ## L4: France-UK TEUTATES Program — EPURE Hydrodynamic Facility and Joint Nuclear Weapons Validation ### Finding: France and the UK jointly operate the EPURE hydrodynamic radiography facility at CEA/DAM's Valduc center under the 2010 TEUTATES Treaty, sharing facility infrastructure for nuclear weapons material behavior studies while maintaining separate experimental programs and national sovereignty over deterrent data.
2. The EPURE facility at Valduc (CEA/DAM center) is described as "the unique worldwide facility capable" of conducting hydrodynamic experiments using plutonium (in sub-critical quantities) to study material behavior under explosive compression — the pre-nuclear phase of weapon operation.
3. EPURE experiments characterize "the state and behaviour of nuclear materials, and especially of plutonium" under compression conditions, providing data to validate computer simulations of weapon functioning.
