The G2 expert system shell (product of
GENSYM Corp.) has been used to build up a prototype intelligent process monitoring and alarm generation system (GPCS - G2-based Plant Computer Subsystem).The GPCS includes an object oriented description of the main subsystems of the plant and concentrates on the fast evaluation and display of the measurements (e.g.
Feedwater Subsystem or Turbine Subsystem) and the alarms . The high-level information, reflecting the actual plant safety status is synthesised from primary measured data by forming global alarms and by evaluating logical diagrams.

For the functional testing of the prototype the plant measurements, processed by the system are provided by a compact simulator of the Hungarian Paks NPP, also developed in the Atomic Energy Research Institute.
