Honeywell Uranium Hexafluoride Processing Facility

The Honeywell Metropolis Works is a uranium conversion facility that transforms uranium oxide into uranium hexafluorid gas for use in nuclear reactor fuel. The conversion process occurs in specialized buildings designed to handle the chemical reactions required for this transformation.

Operations began in 1958 under contract with the U.S. Atomic Energy Commission, and the facility underwent significant safety improvements following the 2011 Fukushima incident. These upgrades strengthened containment and monitoring systems throughout the plant.

The facility maintains strong connections with the Metropolis community through employment opportunities and economic contributions to the local infrastructure.

The facility is not open to public visits due to its chemical processing nature and security requirements. You can view the exterior from roads nearby without entering the property grounds.

This is the only uranium conversion plant operating in the United States and supplies a major share of global demand for the material. Its role makes it a critical piece of nuclear fuel supply around the world.
