EGPR 2015

Host university: University of Zagreb, Croatia

Industrial partner: INETEC - Institute for Nuclear Technology, Zagreb, Croatia


Task: Remotely operated submersible device for inspecting of welds in nuclear reactor pressure vessel.
 
The project partner for 2015 was INETEC - Institute for Nuclear Technology, based in Zagreb, Croatia. For more than twenty years, INETEC has been a name synonymous with technological and service excellence in nuclear industry. They have gained international recognition for developing technologies for nuclear power plant examination and repair, inspection and repair services, as well as various engineering studies within a broad scope of activities. In doing so, they are active in permanent programs of research, development, design, construction and fabrication of equipment, tools, plugs and probes, including software and instruments for non-destructive examination.
 
For the EGPR project, students were set the challenging task of designing a remotely operated device for inspecting the reactor pressure vessel in nuclear power stations. Many aspects of the problem were investigated including; underwater propulsion, accurate location of vessel features, non-destructive testing methods and scanning procedures, power and data connections, and vehicle control. The most promising design concept identified by INETEC used perpendicular rails and suction cups to ‘walk’ along the surface of the reactor vessel, allowing fast and accurate scanning of welds. Five teams of students each focussed on different aspects of the design, and excellent teamwork and communication were required to ensure compatibility between subsystems in the final prototype.
 
The week long workshop was hosted by Zagreb University in early July, with the successful assembly and testing of the prototype performed at INETECs facilities.
