Assessment of Construction Quality at the Hanford Site Waste Treatment and Immobilization Plant

The U.S. Department of Energy Office of Nuclear Safety and Environmental Assessments, within the independent Office of Enterprise Assessments (EA), conducted an assessment of construction quality and the implementation of the quality assurance program at the Hanford Site Waste Treatment and Immobilization Plant (WTP) from September 11 to 14, 2017.  EA performed this assessment in the broader context of an ongoing program of quarterly assessments of construction quality at the WTP construction site.

The scope of this EA assessment included observing ongoing work activities; reviewing the program that Bechtel National, Inc. (BNI) and its subcontractor, Waste Treatment Completion Company, utilizes for controlling nonconforming conditions; examining the implementation of certain requirements in the BNI quality assurance program; and following up on issues identified during previous assessments
