Abstract
In order to restart the Research Reactor Trico II, nuclear components are inspected using two main Non-Destructive Testing (NDT) methods, namely Visual Inspection (VI) and Ultrasonic Testing (UT). Visual method was needed to inspect the TANK using underwater camera ARECONT VISION and the USB2.0 endoscope. Ultrasonic method was needed to inspect octagonal concrete structure using a flaw detector Proceq Pundit PL-200PE for uniformity and quality controls. The inspection showed that the reactor tank has not been degraded. Indeed, out of about one hundred photos taken with both underwater cameras, only two shows small degradations on the tank wall. One concerns the horizontal ring 1, which is not well sticked on the tank wall. The second concerns the vertical weld (CV1), which shows a visible spot on the weld due probably to dust accumulation. The biological protection layer of the octagonal concrete structure is not also degraded. The calculated concrete structure elasticity modulus is given by G=192 558,53±43811,93 Mpa
