Independent Oversight Review, Waste Treatment and Immobilization Plant - August 2012

August 2012

Review of the Hanford Site Waste Treatment and Immobilization Plant 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 independent reviews of selected aspects of construction quality at the Hanford Site Waste Treatment and Immobilization Project (WTP). The reviews for this report were performed on site during February 6-10, 2012 and April 30 – May 4, 2012, and were the latest in a series of ongoing quarterly assessments of construction quality performed by Independent Oversight at the WTP.

Independent Oversight determined that construction quality at WTP is adequate in the areas that were reviewed. BNI Engineering developed appropriate corrective actions to disposition the NCRs, CDRs, and PIERs that Independent Oversight reviewed. Concrete placement and inspection activities are adequate, as is pressure testing of installed piping.
