Pueblo Static Detonation Chamber Units Covered, Energized

  • Sprung structures, the tension fabric coverings that will protect the Pueblo Chemical Agent-Destruction Pilot Plant’s three Static Detonation Chamber units, are now complete.

    Sprung structures, the tension fabric coverings that will protect the Pueblo Chemical Agent-Destruction Pilot Plant’s three Static Detonation Chamber units, are now complete.

  • Local utility electrical power is now connected to the Static Detonation Chamber site at the Pueblo Chemical Agent-Destruction Pilot Plant.

    Local utility electrical power is now connected to the Static Detonation Chamber site at the Pueblo Chemical Agent-Destruction Pilot Plant.

Complete protective enclosures now surround three Static Detonation Chamber units at the Pueblo Chemical Agent-Destruction Pilot Plant.

“These Sprung structures are a visible sign of progress, but that’s only part of the story,” said Dan Williams, SDC project manager. “We also started connecting the SDC site to utility electrical power. This achievement will afford the SDC project the opportunity to begin energizing and testing major equipment, starting the transition to operations.”

The units are expected to begin operating in December.

The tension fabric coverings, also known as Sprung structures, shelter the SDC units, which will augment the main plant by destroying munitions not suitable for its automated process.

The first Sprung structure components arrived at the SDC site in September 2019. Work has continued with social distancing and face covering precautions throughout the COVID-19 pandemic.
