AbstractAbstract
[en] A theoretical and experimental study of the slow transient phenomena encountered during emergency core cooling rewetting of pressurized water reactors was done. To perform this study a low pressure and low heat flux water loop was used, with two basic tests sections, one tubular and another annular. After being heated by the Joule effect, the test section was quenched at a constant flow rate by bottom flooding of water at room temperature. The effects of wall temperature and fluid flow rate in tjhe performance of the rewetting process were investigated. Our results were in good agreement with those obtained by other laboratories.

Estudou-se teorico e experimental os fenomenos transitorios lentos envolvidos no processo de remolhamento de nucleos de reatores a agua pressurizada, quando de seu resfriamento de seguranca por injecao de liquido. Para isto, foi utilizado um circuito termico a agua, de baixa pressao e baixo fluxo termico, onde instalou-se dois tipos de secao de testes, uma tubular e outra anular. Apos o aquecimento, da secao de testes, por efeito Joule, ela foi refrigerada por agua, a temperatura ambiente, em escoamento forcado ascendente. Foram investigados os efeitos da temperatura de parede e da vazao de refrigerante na eficiencia do processo de remolhamento. Resultados compativeis com os de outros laboratorios foram obtidos.
