Abstract

REACTOR NUCLEAR DE TIPO SUBMODERADO. COMPRENDE TRES CONJUNTOS: LOS CONJUNTOS FISIBLES (1) CUYAS BARRAS CONTIENEN UNA MEZCLA DE OXIDO DE URANIO Y DE OXIDO DE PLUTONIO; LOS CONJUNTOS FERTILES (2) QUE CONTIENEN BARRAS CONSTITUIDAS PRINCIPALMENTE DE URANIO NATURAL; Y LOS CONJUNTOS (3) QUE FORMAN PARTE DEL SISTEMA DE PARADA COMPLEMENTARIA DEL REACTOR, POR INTRODUCCION DE UNA FUENTE ANTI-REACTIVIDAD EN EL NUCLEO DEL REACTOR, DONDE DURANTE EL FUNCIONAMIENTO DEL REACTOR, LA MATERIA FERTIL DEL NUCLEO CONTENIDA EN LOS CONJUNTOS PERIFERICOS (2), SE TRANSFORMA EN MATERIA FISIBLE BAJO EL EFECTO DE LOS NEUTRONES EPITERMICOS PRODUCIDOS POR LA PARTE FISIBLE DEL NUCLEO. TIENE UTILIDAD POR PERMITIR UNA ECONOMIA SOBRE EXPLOTACION DEL COMBUSTIBLE DEL NUCLEO.
