REACTOR PRESSURE VESSEL HEAD ARCHER is designed to provide eddy current and ultrasound examinations of reactor pressure vessel head penetrations by the use of various test modules and to perform automated surface repairs of the J-groove weld and the tubes’ outside surface, below the weld, on both PWR and VVER types of nuclear power plants. KEY FEATURES different modules used for various types of RPVH geometry easy modules exchange through the docking system without personnel having to enter below the head region full scope inspection of both PWR and VVER RPVH all penetrations accessible without manipulator repositioning remotely operated distance up to 200 meters IP protection level: IP65 main air supply: 6 bar power supply: 110 − 220 VAC, 5 − 60 Hz rotation speed: 12 °/s linear horizontal speed: 100 mm/s linear vertical speed: 100 mm/s linear positioning accuracy: ± 0.2 mm angular positioning accuracy: 0.3° absolute positioning system NON SLEEVED CRDPP MODULE (OPEN HOUSING) used for penetrations without thermal sleeves delivery of eddy current and array of ultrasonic probes at the inner surface of penetrations detection and sizing of circumferential and axial cracks leak path identification with a straight beam water supply and water collecting system 16 PRODUCTS ultrasound probe
