Bechtel’s construction team successfully completed the precision installation of a massive 50-ton (45-metric-ton) shield door at the Waste Treatment Plant (WTP) site in Hanford, Washington. The shield door is in a key area of WTP’s High-Level Waste Vitrification Facility and was installed to extremely tight tolerances, down to five-thousandths of an inch (0.13 millimeters), or less than the diameter of a human hair. The new door is one of six that Bechtel will install at WTP.
