SCORPIO-VVER - Two decades of experience and enhancements in reactor core monitoring and surveillance in central Europe

Popis výsledku v původním jazyce

During the years 1970-80' in the satellite countries of the former Soviet Union more than 24 new reactor builds were started. In the former Czechoslovakia, the new builds were realized with a high degree of input from the local engineers and the local industry. This territory up to today has an indigenous nuclear industry, machinery and nuclear engineering background. Starting with the year 1972, on the territory of Czechoslovakia (now on the territory of the Czech and Slovak Republic) 12 new units of the VVER-440 type of reactors were started to build. Nowadays the 2 oldest units were already shutdown in Slovakia, 4+4 units are still operating in both countries, and 2 units of VVER-440 model V213 are still under construction in Slovakia. The reactors designed lifetime in original configuration are 30 years. During these units' operation period, wide range of modifications and upgrades were performed to strengthen the nuclear safety and the reactors operability. In 2015/16, activities related to the unit operation licenses extension were carried out in both of countries. In scope of strengthening the reactor's core monitoring and surveillance, at Dukovany NPP (CZ, 1998) and at Bohunice NPP (SK, 2001) the original Russian VK3 computation system was completely replaced with an alternative advanced Core Monitoring and Surveillance System (CMS) SCORPIO-VVER. In Hungary, a locally developed "Verona", and on the units under construction in Slovakia the Russian "Kruiz" CMS is used. Nowadays the SCORPIO-VVER CMS presents a nuclear fuel type and fuel vendor independent, advanced computer based reactor core monitoring system with an open and flexible framework, including the latest achievements in the fields of N/F and T/H for reliable and safe reactor operation with high efficiency of fuel cycle. The system's framework governing the know-how and knowledge of 5 European institutes with proven experiences with reactor operation, fuel pattern and fuel campaign design and with utilizing the existing unit's project reserves to increase the reactor operation and fuel campaign efficiency. Since the first installation the SCORPIO-VVER CMS system has a remarkable operating history and experience. More than 18 years of experiences at 6 units of VVER-440 type of reactors in two different countries helps to put the system to a very high level of usability and reliability. Even if the SCORPIO-VVER is installed only on VVER-440 reactors, it could be adapted to the needs of other VVER type of reactors and to needs of education and training centers too.
