Experimental circuit for research on emergency cooling systems of advanced reactors

This paper describes the project and presents the first results of temperature distribution and flow estimates of the Circuit of Natural Circulation developed at the Instituto de Pesquisas Energeticas e Nucleares, IPEN-CNEN/SP, inside of the Project of the Diretoria de Pesquisa e Desenvolvimento of CNEN entitled Amplification and Complementation of the Experimental Facilities of Passive Systems of Advanced Reactor. The objective of that project was adapt the experimental facilities of the Institutions that began research lines in Advanced PWR Reactors. The results obtained show that the circuit is well adapted for the purposes of research of passive emergency cooling systems. (author)
