Scope of the project is an updating of the Fuel Handling Machine Control System (FHMCS), designed and supplied by Ansaldo Nucleare in 2005. The FHMCS was designed for providing required refueling operations with Fuel handling Machine MPS-V-428M type, at Tianwan NPP, Units 1 and 2 (People's Republic of China), with high operational safety during fuel movements in compliance with norms and regulations, acting at Nuclear Power Plants.
The FHMCS consisted in upper and lower level computer control system (CCS) including human-machine interface (HMI), actuating control system (ACS), remote I/O, manual emergency console (MEC) and voice system. It was designed for movement of FHM mechanisms and continuous monitoring of refueling parameters. The updating consists is a replacement of old servers with more powerful and based on up to date technology, their relocation from the Operator Console to inside of additional cabinets, also containing the overload protection, which has been added as part of the current project scope.
The ANN's scope includes the design of the additional cabinets, including their qualification against the applicable seismic requirements, its purchasing, Factory Acceptance Tests and delivery to Volgodonsk, where they will be connected to the Fuel handling Machine for final tests before delivery to the site.
