National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Development of Visual Criteria for Evaluation of Corroded TRU-Waste Drums at the DOE Hanford Site.

DE2004834443

Publication Date	2004
Personal Author	Cannell, G. R.
Page Count	20
Abstract	Fluor Hanford, Inc., at the Department of Energy (DOE) Hanford Site, has recently begun retrieving some 37,000 contact-handled, suspect-Transuranic or 'Retrievably Stored Waste' (CH-TRU) waste drums from its Low Level Burial Grounds (LLBG). The drums are being retrieved, processed and prepared for eventual shipment to the DOE Waste Isolation Pilot Plant (WIPP). Immediately upon retrieval, the drums are visually inspected against requirements identified in the facility Authorization Basis to ensure they are safe for handling and fit for on-site transfer. A number of the retrieved drums did not meet specified corrosion criteria and as such required structural evaluation by Ultrasonic Test (UT) thickness checking (including mechanical surface prep) or overpacking into a Conex-type container prior to transfer.
