Abstract

REATOR DE ÁGUA PRESSURIZADA E MÉTODO DE OPERAÇÃO DE UM REATOR DE ÁGUA PRESSURIZADA. A invenção se refere a um reator de água pressurizada (2), compreendendo um circuito de refrigeração de reator primário (4) conduzido por um refrigerante de reator primário durante a operação e compreendendo um sistema de controle químico e de volume (14) para o refrigerante de reator primário, o sistema de controle químico e de volume (14) compreendendo, ao longo da direção de fluxo do refrigerante de reator primário, uma linha de descarga (18), uma bomba de carga de alta pressão (32) com uma dada pressão de descarga e uma linha de carga (34) conduzindo ao circuito de refrigeração de reator primário (4), o sistema de controle químico e de volume (14) compreendendo ainda um sistema de hidrogenação (16) com um fornecimento de hidrogênio (36) e uma linha de alimentação de hidrogênio (38). A fim de alcançar injeção de hidrogênio rápida e eficiente no refrigerante de reator primário, uma bomba de alimentação de alta pressão (40) é disposta na linha de alimentação (38) para fornecer uma pressão de gás maior do que a pressão de descarga da bomba de carga (32), em que a linha de alimentação (38) descarrega na linha de carga (34).
