Abstract
For its restart, components oFor its restart, components of research reactor TRICO II are subject of Non-Destructive Testings (NDT). Its STAHL hoist lifting hook 5000kg was inspected by colored liquid penetrant method for the research of surfaces defects, through white light in 750 lux. Result obtained indicates that it is not degraded. Indirect visual inspection by the multifunction video endoscope KC 350 was used to control internal wall of heat exchanger secondary circuit piping, some photos of internal wall were captured. The ultrasonic method consisted in measuring thickness of internal and external part of piping of the heat exchanger secondary circuit using thickness gauge ATG II with built-in 4.00mm calibration block. Results obtained by visual inspection showed the presence of rust and corrosion. The ultrasonic method showed thickness variation on controlled surface due to deposit rust (high value of thickness) and corrosion (low value of thickness). This work is carried out as part of maintenance, periodic testing and inspection for proper management of the TRICO II reactor.
