The Program Executive Office, Assembled Chemical Weapons Alternatives (PEO ACWA) announced last week that repairs have been completed on the explosive destruction system at the Pueblo Chemical Agent-Destruction Pilot Plant.

Repair work began after damage to the system's door seal was found Aug. 7 during a regular cleanout operation following successful munitions destruction. According to Bruce Huenefeld, the site's project manager, it is believed that damage occurred due to a small metal fragment being lodged between two surfaces, and the dent was made after these surfaces were pressed together in the sealing process.

To repair the damage, an indent on the sealing surface had to be machined down, built back up and then added to a newly welded surface in order to bring the system to original specifications. During this process, tests were performed and a final helium leak test cleared the system to bring it back to its original operating condition.

"With approval of the repair documentation package by the Colorado Department of Public Health and Environment, agent operations can resume,” Huenefeld said.

The Pueblo facility is one of two of its kind in the U.S. and is tasked with the elimination of chemical arm stocks. The facility has been successful in dismantling 347 chemical munitions.
