The EOP visualization module integrated into the plasma on-line nuclear power plant safety monitoring and assessment system

An ambitious project to replace the unit information systems (UISs) at the Hungarian Paks nuclear power plant was started in 1998-99. The basic aim of the re construction project is to install a modern, distributed UIS archit ecture on all four Paks VVER-440 units. The new UIS includes an on-line pla nt safety monitoring and assessment system (PLASMA), which contains a criti cal safety functions monitoring module and provides extensive operator supp ort during the execution of the new, symptom-oriented emergency operating p rocedures (EOPs), PLASMA includes a comprehensive EOP visualization module, based on the COPMA-III procedure-handling software developed by the Organi zation for Economic Cooperation and Development, Halden Reactor Project. In tranet technology is applied for the presentation of the EOPs with the use of a standard hypertext markup language (HTML) browser as a visualization t ool. The basic design characteristics of the system, with a detailed descri ption of its user interface and functions of the new EOP display module, ar e presented.
