Scaling of small break LOCA in VVER 1000 system
, 2005 This paper deals with the problem of scaling complex scenario measured in experimental facilities and replicated by the use of Relap5 code. ‘Kv-scaled’ calculation plays an important role in the frame of the “on-transient qualification” of the ...

Analysis of natural circulation phenomena in VVER-1000
, 2004 In all light water reactors (LWR), natural circulation is an important passive heat removal mechanism. In the present paper, the natural circulation phenomena are studied with reference to step-wise coolant inventory reduction and a small break loss-of-

Vertical steam generators for VVER NPPs [PDF]
Nuclear Energy and Technology, 2018 Steam generators for NPPs are the important large-sized metal consuming equipment of nuclear power installations. Efficiency of steam generator operation determines the overall service life of the whole nuclear facility. The main aim of the current study is to analyze advantages and shortcomings of horizontal and vertical types of steam ...
