Scaling of Small Break LOCA in VVER 1000 System
2005This paper deals with the problem of scaling complex scenario measured experimental facilities and replicated by the use of Cathare2 code. ‘Kv-scaled’ calculation an important role in the frame of the “on-transient qualification” of the nodalization owing the procedure envisaged at Pisa University) and to evaluate the importance oe scale-distortions in

Equilibrium thorium fuel loading in VVER-1000 reactor
Proceedings of the 2014 15th International Scientific Conference on Electric Power Engineering (EPE), 2014Thorium can be utilized in Pressurized Water Reactors (PWR) as ThO 2 fuel matrix supported by fissile materials. In this analysis, VVER-1000 reactor was taken as a representative of the PWR reactor group. The thorium fuel matrix was mixed with fissile material in form of pure 233U, enriched uranium (19.7 % enrichment) and Reactor-Grade plutonium ...

CFD Simulation of Slug Mixing in VVER-1000 Reactor
Volume 4: Computational Fluid Dynamics, Neutronics Methods and Coupled Codes; Student Paper Competition, 2006Recently, the safety analyses of VVER and PWR reactors have dealt with the possibility of reactivity-induced accidents related to the penetration of a water slug with low boron concentration into the reactor core. Loop seals at the reactor coolant pump (RCP) suction are the most likely places for the formation of these slugs.

VVER-1000 SFAT-Specification of an industrial prototype
2000The project to develop a Spent Fuel Attribute Tester (SFAT) for Ukrainian VVER-1000 facilities is going on under the Task FIN A 1073 of the Finnish Support Programme to the IAEA safeguards. In the SFAT method [1] the verification is based on an unambiguous detection of gamma radiation of the fission products.
