Description
Characteristics of a 1200 MWe binary breeder reactor with annular core fueled with metallic 233U- 238U-Zr, Pu- 238U-Zr and Th in the blankets have been analyzed. The Doppler effect is small as expected in a metal fueled fast reactor. The sodium void reactivity is, in general, smaller than in homogeneous fast reactors fueled with metallic fuel and with 1 m core height. The worths of available control is high and there is a large shutdown margin throughout the operational cycle. There are flexibility in blankets fueling in the two cycles, uranium and thorium, with doubling times of about 20 years. (author)
Abstract (Portuguese)
Foram analisadas as caracteristicas de um reator regenerador binario de 1200 MWe com nucleo do tipo anular, carregado com combustivel metalico 233U- 238U-Zr, Pu-238U-Zr e Th nos envoltorios. O efeito Doppler e pequeno, como esperado em reatores rapidos com combustivel metalico. A reatividade de vazios no sodio e, em geral, menor que nos reatores rapidos homogeneos carregados com combustivel metalico e com 1 m de altura de nucleo. O valor de controle disponivel e alto e existe uma grande margem de desligamento por todo o ciclo operacional. Existe flexibilidade no carregamento dos envoltorios, e e possivel uma regeneracao bem equilibrada nos dois ciclos, uranio e torio, com tempos de dobramentos em torno de 20 anos.
