The results of postirradiation examinations of VVER-1000 and VVER-440 fuel rods
Journal of Nuclear Materials, 1991Abstract The paper presents the results of postirradiation examination of the fuel rods having different fuel-cladding gaps, pellet densities, pellet inner diameters and so on. The fuel rods were irradiated in the material science reactor (MR) of the Kurchatov Institute of Atomic Energy and at 4 unit of the Novo-Voronezh nuclear powerplant. Some data

The SCORPIO-VVER Core Monitoring and Surveillance System for VVER Type of Reactors
Volume 1: Plant Operations, Maintenance, Engineering, Modifications, Life Cycle and Balance of Plant; Nuclear Fuel and Materials; Plant Systems, Structures and Components; Codes, Standards, Licensing and Regulatory Issues, 2014The SCORPIO-VVER core monitoring and surveillance system has proved since the first installation at Dukovany NPP in 1999 to be a valuable tool for the reactor operators and reactor physicists. It is now installed on four units of Dukovany NPP (EDU, Czech Republic), on two units of Bohunice NPP (EBO, Slovak Republic) replacing the original Russian VK3 ...

Ballooning Experiments with VVER Cladding
Nuclear Technology, 2005The results of single-rod and bundle ballooning tests with VVER (E110 type) cladding are presented. The comparative study of E110 and Zircaloy-4 showed a significant difference in behavior at 800 to 1000 deg. C. The local maximum of mechanical strength was observed at a low oxidation rate. The pressurization rate played a considerable role in the burst

PRESSURE VESSEL CALCULATIONS FOR VVER-440 REACTORS
Reactor Dosimetry in the 21st Century, 2003For the determination of the fast neutron load of the reactor pressure vessel a mixed calculational procedure was developed. The procedure was applied to the Unit II of Paks NPP, Hungary. The neutron source on the outer surfaces of the reactor was determined by a core design code, and the neutron transport calculations outside the core were performed ...

Increasing fuel burnup in VVER
Atomic Energy, 2008The results of investigations of fuel burnup increase in VVER are presented. The influence of the costs of different technological stages, changes in the number of refuelings and run time, fuel enrichment and waste, and the consumption of natural uranium on increasing burnup is examined. An analysis taking account of the uncertainty of future prices is

The results of a search for the optimal water-uranium ratio for VVER with no changes to the fuel elements and assemblies are presented. It is shown that decreasing the volume of a fuel pellet while maintaining the same 235 U load as a result of increasing the enrichment will decrease the specific consumption of uranium and increase the run time.

Development of an in-reactor monitoring system for VVER
Atomic Energy, 2009More than 20 power-generating units with VVER-1000 and more than 30 with VVER-440 reactors are currently operating in our country and abroad. This article examines the creation and development of in-reactor monitoring systems for different types of VVER reactors as experience in operating them is gained and the level of knowledge increases.
