The 190-D complex equipment and structure was identified for decontamination and demolition by the United States Department of Energy (DOE) in 1992. The work was planned and field activities began in 1993. The building was imploded on August 17, 1995. The complex was decontaminated by removing the residual equipment, hazardous materials, dismantling and removing the radiologically contaminated test loops, and mechanically decontaminating radiologically contaminated concrete surfaces. Demolition of the complex used lessons learned from previous similar jobs and was accomplished using conventional and explosive demolition techniques. The 190-D complex was the fourth 100 Area pumphouse to be demolished. The pumphouse complexes at the 100-F and 100-H Areas were demolished over ten years ago. The 190-F complex was leveled with explosives and the 190-H complex was pulled over with heavy equipment. Both the F and H pumphouse projects experienced some difficulties with their particular demolition method. The pumphouse complex at 100-B was demolished in fiscal year 1994 with a combination of heavy equipment and explosive demolition techniques.
