Abstract

LA PROTECCION CONTRA LAS CONSECUENCIAS DE LA CAIDA ACCIDENTAL DE UN RACIMO DE BARRAS DE CONTROL ESTA ASEGURADA POR CUATRO CADENAS COMPORTANDO CADA UNA DOS DETECTORES DE FLUJO NEUTRONICO (D1A, D1B), DOS CIRCUITOS DE TRATAMIENTO PRIMARIO (R1A, S1A Y R1B, S1B) ASOCIADOS A ESTOS DOS DETECTORES PARA SUMINISTRAR CADA UNO UNA SEÑAL PRIMARIA DE CAIDA EN CASO DE DECRECIMIENTO RAPIDO DEL FLUJO MEDIDO POR EL DETECTOR CORRESPONDIENTE, Y UNA PUERTA (P1) DEL TIPO OU PARA SUMINISTRAR UNA SEÑAL DE CAIDA POR SALIDA DE LA CADENA EN PRESENCIA DE AL MENOS UNA SEÑAL PRIMARIA. LOS DETECTORES (D1A, D4B, D3A, D1B, D2A, D3B, D4A Y D2B) ESTAN DISTRIBUIDOS ANGULARMENTE ALREDEDOR DEL EJE VERTICAL (A) DEL CORAZON (2). UN CIRCUITO DE TRATAMIENTO SECUNDARIO (6) MANDA UNA PARADA DE URGENCIA DEL REACTOR CUANDO RECIBE SEÑALES DE LA CAIDA POR SALIDA DE AL MENOS DOS CADENAS.
