Definitions
- the 105 required pressure in a prefabricated measuring chamber. Cameras are cut off from the boot. Lives more to equalize temperature and pressure. Turns off the gamma radiation detectors of Urana-235. The measurement of the intensity of gamma radiation leads to two channels. The first channel connects to the power line 185.7 kE ⁇ , the second channel - to register gamma
- emissions are determined by taking into account the main component of the analytical spectrum, which characterizes the natural alpha-decay of hurricane-235; that a change in the intensity of gamma radiation is carried out by the user due to the energy of the main analytical analyzer, which is a characteristic of 23%; that a gamma radiation intensity measurement is carried out in an energetic

Abstract
L'invention se rapporte à l'analyse des matières fissiles par procédés à rayonnement et sert au contrôle opérationnel de l'enrichissement de l'hexafluorure d'uranium dans la fabrication à séparation d'isotopes. L'intensité des rayons gamma, la température et la pression sont déterminées par les résultats pondérés des mesures sur des intervalles identiques lors de la mesure du temps courant sur une valeur égale à une fraction de temps de l'intervalle temporel. La valeur calculée de la fraction massique de l'uranium 235 se rapporte au temps courant qui tombe sur la fraction de temps calculée. Le système de contrôle comprend une chambre de mesure (1) avec une unité de détection (6), des capteurs de température (7) et de pression (8), connectée à un collecteur de gaz d'hexafluorure d'uranium (4), un contrôleur (11) avec des compteurs d'impulsions électriques (15-17) et un analyseur de spectre gamma (18), des adaptateurs de signaux (9, 10), un bus de données interne (20), une unité de collecte (21), de commande et de traitement de données. Le contrôleur comprend au moins trois discriminateurs (12-14) et une minuterie (19). Les entrées des discriminateurs sont connectées à la sortie du détecteur de rayons gamma, et la sortie de chaque discriminateur est connectée à l'entrée du compteur individuel des impulsions électriques, connecté par sa deuxième entrée à la sortie de la minuterie. Les sorties de la minuterie et des adaptateurs sont connectées par une voie d'échange de données avec le bus de données interne (20). L'unité de collecte, de commande et de traitement de données par un réseau d'interface interne (22) est connectée au réseau de calcul de gestion (23).
