Compensation of neutron flux detectors by digital methods
Description
In nuclear reactors there is a system for determining the reactor power by measuring the neutron flux. The detectors presently used contain impurities which contribute up to 20 percent of the total response in the form of exponential terms that increase the response time. It is important for the control of the reactor to have the most exact possible knowledge of the neutron flux. Analog methods are currently used to make the detector signals proportional to the neutron flux. Compensation could be carried out using numerical methods on a digital computer. Results of simulations carried out using fast Fourier transforms are encouraging
Abstract (French)
Dans les reacteurs nucleaires actuels, il existe un systeme qui a pour but de determiner le niveau d'operation de puissance, au moyen de la detection et de la mesure du flux de neutrons. Les detecteurs utilises contiennent des impuretees qui contribuent pour jusqu'a 20 pourcent de la reponse totale, sous forme de terms exponentiels qui augmentent le temps de reponse. Une connaissance du flux la plus exacte possible est importante pour le controle du reacteur. Le signal du detecteur doit etre rendu proportionnel a ce qui'il mesure. Il faut donc le compenser. Le methode analogique est utilisee a l'heure actuelle. La compensation peut etre faite par des methodes numeriques sur ordinateur digital. La theorie permet d'utiliser la technique de transformee de Fourier rapide. Des resultats preliminaires ont ete deja obtenus et sont tres encourageantsAdditional details
