Resumo
Studies have been carried out on nuclear reactors with safety
characteristics that do not depend on external intervention by operators or even
on an external energy source. In this type of reactors, cooling is carried out by
natural circulation, both during normal operation and during shutdown. For this
reason, the STAR experiment was built in the IEA-R1 research reactor
installed at the Institute for Energy and Nuclear Research (IPEN) – Brazil, with
the aim of simulating experiments with the RELAP5 code in order to validate
its models in two scenarios: total and partial emptying of the STAR. The
results obtained with the RELAP5 code were compared to the experimental
ones for the two proposed scenarios. These results showed that the
mathematical correlations contained in RELAP5 are capable of reliably and
safely reproducing the phenomenology of natural circulation in nuclear
reactors.
