Abstract

trata-se de um sistema e método para realizar varredura ativa em uma vareta de combustível nuclear. o sistema inclui um gerador de nêutron eletricamente acionado que inclui uma fonte de íons, um acelerador e um alvo; um moderador que circunda o gerador de nêutron e configurado para moderar nêutrons gerados pelo gerador de nêutron; um canal de vareta de combustível disposto dentro do moderador, sendo que o canal de vareta de combustível é configurado para receber uma vareta de combustível nuclear e submeter a vareta de combustível nuclear a um fluxo de nêutron predeterminado; e uma pluralidade de detectores de radiação. quando a vareta de combustível nuclear é submetida ao fluxo de nêutron predeterminado, os nêutrons induzem uma radiação secundária de emissões gama imediatas e atrasadas, emissão de nêutron ou uma combinação das mesmas que são detectadas pela pluralidade de detectores de radiação para determinar uma quantidade de material físsil na vareta de combustível nuclear e uma distribuição espacial do material físsil ao longo de um comprimento da vareta de combustível nuclear.
