“BLACK BOX” SYSTEM TO PRESERVE INFORMATION IN DESIGN AND BEYOND-DESIGN ACCIDENT CONDITIONS

The “Black Box” system is designated to store and provide personnel with information on parameters of NPP units in accident and post-accident conditions of design and beyond design accidents.

Functions of the “Black Box” system:

  • acquiring information from systems-data sources;
  • registering and storing information in a long-term archive;
  • providing personnel with information on parameters of NPP units in a form of diagrams and videograms.

Composition of the “Black Box” system:

  • a complex for registration and presentation of data received from a data concentration subsystem (KRPD), consisting of:
  • redundant data servers;
  • a server of a long-term archive;
  • a workstation of a technologist;
  • an engineering station;
  • hardware forming a radio channel for data transmission;
  • a complex for concentration of data received from a data input subsystem (KKD), consisting of:
  • redundant data acquisition servers;
  • hardware forming a radio channel to transmit data to KRPD;
  • a complex for input of data from systems-sources of unit data, consisting of:
  • redundant gateways for optical branching and communication, consisting of a gateway of communication with the source systems and an optical branching cabinet that assures receipt of data from external systems and transmission of signals to IVS and SRVPE (branching);
  • hardware forming a radio channel to transmit data to KKD.

System advantages:

  • use of a highly-reliable approved radio channel for data transmission;
  • implementation of data exchange between components via redundant fiber-optical communication links;
  • high fail-safety of the system due to use of redundant hardware.

Safety class – 3.
Safety category – С.

Implementation facilities:

  • Khmelnitsky NPP, units 1, 2
  • Rivne NPP, units 1-4
  • Zaporizhzhya NPP, units 1-5
