  3. Abstract:
  4. Using of natural circulation concepts in nuclear and non-nuclear industry is very important. One of important methods in new designs of "innovative" fission reactor technologies is natural circulation scene. Natural circulation is based on buoyancy force; density differences between hot and cold legs including core and steam generators, and height of hot and cold zones. In this paper we studied natural circulation phenomena in two different heights of hot and cold zones by using of RELAP5 system code. Natural circulation Flow Map (NCFM) made for both cases and compared with experimental data. We have considered main components and systems of WWER-1000 plant in our model, such as pressure vessel, steam-generators, feed-waters, and so on
