Under an agreement with the Japanese Science and Technology (STA) and in co-operation with OECD Halden Reactor Project, the NEA supported an international research project, the "SCORPIO" Project, to improve the surveillance capabilities for VVER reactor cores in various operational conditions.
The Norwegian Institutt for Energiteknikk (IFE), the operator of the OECD Halden Reactor Project, carried out the project under the supervision of an international committee set up by the NEA.
The SCORPIO VVER reactor core surveillance system was installed in the Dukovany Nuclear Power Plant in the Czech Republic, for the purpose of developing a general system framework for VVER type reactors. The design phase started in April 1996. The overall structure of the Man-Machine Interface was implemented and several pictures (screens) were made for testing purposes.
