Independent Oversight Review, Waste Treatment and Immobilization Plant - August 2011

August 2011

Hanford Waste Treatment and Immobilization Plant Construction Quality

The Office of Safety and Emergency Management Evaluations (Independent Oversight) within the Office of Health, Safety and Security (HSS) conducted an independent review of selected aspects of construction quality at the Hanford Waste Treatment and Immobilization Project (WTP). The review, which was performed May 9-12, 2011, was the latest in a series of ongoing quarterly assessments of construction quality performed by Independent Oversight at the WTP construction site.

HSS determined that construction quality at WTP was adequate in the areas reviewed. BNI engineering had developed appropriate corrective actions to disposition the NCRs that HSS reviewed. BNI’s re-inspection effort to resolve problems with improper tensioning of structural steel bolts was approximately 90 percent complete and has progressed satisfactorily.
