INETEC provides reactor pressure vessel (RPV) head inspection on both VVER and PWR type of RPV heads and inspection of control rod drive protection pipe (CRD PP) welds on VVER 440.

INETEC RPV head inspection system is capable to perform remote ultrasonic, eddy current and visual examination and local grinding actions. The RPV head system contains innovative and industry proven equipment which today represents the latest and most advanced robot technology that is used for automated inspections. The RPV head inspection system including equipment, procedures and personnel successfully passed several different qualifications according to the ENIQ/IAEA and ASME Section XI requirements.

INETEC RPV head system is employed for all vessel head volumetric and surface examinations, including the examinations of penetration nozzles, J-groove welds and control rod drive protection pipe welds. A contact ultrasonic technique is applied for the examination of the defined sections required by the ASME Code Section XI or other applicable standards, while the eddy current method is applied for the surface examinations up to 3 mm in depth.

INETEC applies high performance non-destructive testing systems and solutions for data recording, processing and analysis. The sophisticated fully automated video system is used for visual inspection of RPV head and CRD PP interior. The complete nondestructive testing systems are fully integrated with the INETEC RPV head system. All operations and control activities during RPV head examinations are remotely controlled by PC workstations located outside of the reactor building.
