Description

This thesis deals with the measurement of the coolant characteristics in PWRs. First, experimental methods not involving radioactive are presented. Then, one presents methods using gamma-ray or neutron transmission for which the following applications are given and detailed: measurement of temperature and flow rate in the pressurizer expansion line by gamma-ray transmission; measurement of the pressurizer level by radiation transmission; measurement of the mass of water in the tank, after reactor shutdown, by gamma-ray detection; measurement of the vacuum fraction in a hot branch by gamma-ray transmission

Abstract (French)

Cette these traite de la mesure des caracteristiques du fluide de refroidissement dans les reacteurs de puissance a eau sous pression. On presente tout d'abord des methodes experimentales n'utilisant pas les phenomenes radioactifs. On s'interesse ensuite a des methodes utilisant la transmission de gamma et de neutrons pour lesquelles on presente les applications suivantes: mesure de temperature et de debit dans la ligne d'expansion du pressuriseur par transmission gamma; mesure du niveau du pressuriseur par transmission de rayonnements; mesure de la masse d'eau dans la cuve apres arret du reacteur par detection gamma; mesure de la fraction de vide dans un branche chaude par transmission de gamma
