“…In order to develop such monitors there have been many studies using several methods such as Feynman-α 1) and neutron noise analysis. 2,3) With the recent development of computer technology, these methods can be used in an on-line real time monitor. However, these methods require analysis of a certain length of time sequence data to estimate the subcriticality using complicated statistical theory.…”

“…(2) In the environment where subcriticality is measured, it is normally expected that the neutron flux level is quite low. Therefore the fluctuation of the neutron signal is quite large, which makes the calculation of reactivity using the inverse kinetics equations difficult.…”

“…O métodoé uma ferramenta versátil queé aplicada [33] em medidas de carregamento inicial de reatores, controle de qualidade de elementos combustíveis, plantas de processamento e reprocessamento de combustíveis, reatores de potência zero, identificação de armamento nuclear, e monitoração de instalações de armazenamento. Coeficientes de multiplicação da ordem 0,3 podem ser obtidos em aquisições de dados da ordem de segundos, sendo provavelmente um dos métodos a serem empregados na monitoração de núcleos de potência/transmutação subcríticos 6 .…”
