Summary Sheet

 

TTP#: CH1-0-C211; Tech ID: 3070
Project Overview
Hanford, Idaho National Engineering and Environmental Laboratory (INEEL), Savannah River Site (SRS), West Valley (WV), and Oak Ridge (OR) share a common need to assess and confirm the integrity of their aging High-Level Waste (HLW) storage tanks. Nondestructive Evaluation (NDE) methods are commonly used to collect data on the conditions of materials and structures. The sites will benefit from an activity that promotes collaboration and information sharing relative to NDE issues. The Center for NDE (CNDE) has an extensive history in working with industry on collaborative projects that solve difficult problems. CNDE will initiate a collaborative activity that involves the five main HLW storage facilities. CNDE will assist the sites in solving NDE related technical issues by: 1) coordinating both inter- and intra-site information and technology exchange and 2) providing NDE related technical support and review.

Technology Description
 The Tanks Focus Area (TFA) and Robotics Crosscut Program (RBX) are developing systems for deployment at Hanford and the Savannah River Site (SRS) to assist in inspections and examinations of tank integrity. Both sites need access to the annulus of double shell tanks for deployment of Nondestructive Evaluation (NDE) technologies. The Hanford site is also interested in the surfaces at or near the bottom of large underground storage tanks. During FY 2001 functions and requirements will be determined and technology alternatives evaluated. It is expected that magnetic crawler vehicles will play a role in the deployment of these NDE technologies.
