T-Scan Surveys of Interim Storage Tank, Numbers 1, 2, and 3, Basin F, Rocky Mountain Arsenal
Abstract
Over the period March 13-20, 1989, a series of T-scan thickness mapping surveys were conducted to establish a corrosion monitoring baseline of storage tank 2. Continuation of the program in October, 1989, included re- scanning of the tank 2 baseline areas, plus establishing baseline data on tanks 1 and 3. This report describes and documents the scanning done during the October survey. The three storage tanks were subjected to eight vertical automated thickness mapping examinations using the P-scan equipment. Two horizontal scans were also performed for each tank. The areas scanned revealed only slight variations of wall thickness, although a small localized area of tank 2 was found to have experienced a wall loss of 0.090 inches since March. Radiographic surveys were performed on the attachment valves, V-1 through V-8. Two valves on tank 2 were found to have corrosion.
