Review of the Hanford Site Waste Treatment and Immobilization Plant Project Construction Quality
The U.S. Department of Energy (DOE) Office of Enforcement and Oversight (Independent Oversight), within the Office of Health, Safety and Security, conducted an independent review of selected aspects of construction quality at the Hanford Site Waste Treatment and Immobilization Plant (WTP). The review, which was performed November 14-17, 2011, was the latest in a series of ongoing quarterly assessments of construction quality performed by Independent Oversight at the WTP construction site.
Independent Oversight determined that construction quality at WTP was adequate in the areas reviewed. BNI Engineering has developed appropriate corrective actions to disposition the NCRs and CDRs that were reviewed. Concrete placement and inspection activities are adequate, as are the independent weld inspections performed by DOE-WTP.
