APARATO PARA SUPERVISAR LA MAGNITUD DE UNA CANTIDAD VARIABLE QUE VARIA CON EL TIEMPO DE MANERA POCO FRECUENTE

摘要

In a nuclear reactor, an improved method and apparatus for monitoring the nuclear reactor flux which varies with time over a wide range by: detecting the successive flux variations translated into the form of pulses during a succession of consecutive time intervals of equal duration; producing successive counts each representing the number of pulses occurring during each interval in which at least one pulse occurs; producing successive counts each representing the number of intervals between the end of a respective interval in which at least one pulse occurred and the end of the immediately preceding interval in which at least one pulse occurred; and storing representations of the successive counts produced, thereby saving the storage capacity for storing the monitored information.
