The development of Vulcan is carried out by the Ryazan Metal-Ceramic Devices Plant (RZMKP), the only Russian manufacturer of magnetically controlled sealed contacts. Sensors are installed inside the valves of steam pipelines and control their closing process without requiring power. Thanks to their compact size and high reliability, the sensors are capable of operating at temperatures up to 350 degrees Celsius and can withstand mechanical shocks with accelerations of up to 150 g.
Additionally, the sensors have category one seismic resistance, which allows them to operate even during maximum design earthquakes. RZMKP General Director Sergei Maksimov emphasized that this development is unique and will significantly increase the safety of nuclear power plants.
