Robotic system for fragmentation of steam generators (StarGate)
The robotic complex “StarGate” was created in response to a request to design and deliver a device for the Nuclear Power Plant (NPP) V1 in Jaslovské Bohunice for the fragmentation of 12 steam generators. To meet the NPP’s requirements, a transdisciplinary team was assembled, consisting of experts in robotics, cybernetics, machining technologies, materials research, and nuclear energy. The synergy of specialists from all these key fields led to a unique solution with parameters and features that are beyond the current state of the art. The main differentiating parameters compared to the state of the art are as follows: <ns0:list list-type="bullet"><ns0:list-item> Higher production efficiency and work productivity, comparable even to flame cutting (cutting speed of 1.7 mm/s with a wall thickness of 140 mm). The complete fragmentation of a single steam generator (140 tons) took 45 days. </ns0:list-item><ns0:list-item> A higher level of process automation and intelligent optimization. </ns0:list-item><ns0:list-item> Minimal radiation exposure for workers. </ns0:list-item><ns0:list-item> Minimal aerosol generation and reduced spread of contamination to the surrounding environment. </ns0:list-item><ns0:list-item> Shorter fragmentation time, thereby reducing overall costs (The complete fragmentation of a single steam generator (140 tons) took 45 days). According to today’s data, there are almost 100 steam generators in the world awaiting fragmentation and further processing (IAEA). </ns0:list-item></ns0:list>
