【 摘 要 】

This document presents the results and documentation of the non-destructive ultrasonic examination (NDE) of tank 241-AP-107. An NDE contractor was retained to provide and use an ultrasonic inspection system (equipment, procedures, and inspectors) to scan a limited area of the primary tank wall, welds, and lower knuckle of double-shell tank 241-AP-107. The exam found no reportable indications of wall thinning, pits, or crack in excess of the acceptance criteria.
