Plant Safety Monitoring and Assessment System (PLASMA) Project
Joint project

PAKS control room.


Under an agreement with the Japan Atomic Energy Research Institute, (JAERI), the NEA supported an international research project with the goal of developing a plant safety monitoring and assessment system, known as the PLASMA Project, for use with VVERs*. This project was completed in 2000.

The Norwegian Institutt for Energiteknikk (IFE), the operator of the OECD Halden Reactor Project, carried out this project with the Hungarian Academy of Sciences (KFKI), the Atomic Energy Research Institute of Hungary (AEKI), and the PAKS Nuclear Power Plant Ltd, where the system was implemented and demonstrated.

The PLASMA system was intended to be generic in nature and thus applicable to various VVERs. In addition to a target installation at the Paks nuclear power plant in Hungary, a comprehensive user training programme was implemented.

The data package for the PLASMA project may be requested at PLASMA PROJECT, Plant Safety Monitoring and Assessment System.

* Note: In Russian, VVER comes from водо-водяной энергетический реактор, which transliterates as Vodo-Vodyanoi Energetichesky Reaktor or water-water energetic reactor.
