StarGate

Description

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: • 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. • A higher level of process automation and intelligent optimization. • Minimal radiation exposure for workers. • Minimal aerosol generation and reduced spread of contamination to the surrounding environment. • Shorter fragmentation time, thereby reducing overall costs (The complete fragmentation of a single steam generator (140 tons) took 45 days). The interest of customers and the professional public in StarGate results from the current renaissance of the nuclear energy industry. The number of new NPPs being prepared for construction is increasing, which prompts the acceleration of the process of decommissioning old NPPs, both to create space in established locations for this type of industry, as well as to obtain higher efficiency of electricity production in new NPPs. According to today's data, there are almost 100 steam generators in the world awaiting fragmentation and further processing (IAEA). And we are ready to serve.
