Abstract

The measuring device is capable of continuously measuring boron content, primarily in nuclear power stations, which was hitherto only possible in a discontinuous manner. It essentially comprises a flow-type container having a neutron source, a neutron counter tube and moderator, and a microprocessor-controlled evaluating electronic system. The neutron flux generated in the neutron source is suitably thermalised and reflected in a polyethylene moderator. The reflected neutron flux passes through a water column enriched with boric acid and is attenuated as a function of the boron concentration level, this attenuation being determined with the aid of a neutron counter tube. The basic arrangement is as shown in the accompanying drawing in section 3. <IMAGE>

Description

BESCHREIBUNG:DESCRIPTION:

Titel: Meßeinrichtung zur kontinuierlichen Oberwachung von Borkonzentrtion.Title: Measuring device for continuous monitoring of boron concentration.

Gattung des Anmeldungsgegenstandes: Die Erfindung betrifft eine MeBeinrichtung.zur kontinuierlichen .Oberwachung der Konzentration von in Flüssigkeiten aufgelöster Borsäure nach dem Pri.nzip der Neutronenabsorption.Type of the subject of the application: The invention relates to a measuring device continuous monitoring of the concentration of dissolved in liquids Boric acid based on the principle of neutron absorption.

Stand der Technik: Nach dem bisherigen Stand der Technik wurde die Borkonzentration auf dem Weg der Titration erfaßt.State of the art: According to the previous state of the art, the Boron concentration recorded on the way of the titration.

Kritik des Standes der Technik: Das Titrationsverfähren ist ein relativ aufwendiges, diskontinuierl iches Verfahren mit stetig.. anfallenden chemischen.Abfällen.Criticism of the Prior Art: The titration process is a relative one Complex, discontinuous process with constantly .. accumulating chemical.waste.

Aufgabe: Der Erfindung liegt die Aufgabe zugrunde, von der Diskontinuität zur Kontinuität überzugehen, ohne daß chemische Abfälle anfallen.Task: The invention is based on the task of the discontinuity move to continuity without generating chemical waste.

Lösung: Die auf Borkonzentration zu überwachende Flüssigkeit (Gemisch) strömt kontinuierlich durch die Meßei.nrichtung, wodurch eine kontinuierliche Mes.sung ermöglicht wird.Solution: The liquid (mixture) to be monitored for boron concentration flows continuously through the measuring device, whereby a continuous measuring is made possible.

Das Meßprinzip: Der in einer oder mehreren Neutronenquellen erzeugte Neutronenfluß wird entsprechend der zu bestimmenden Borkonzentration geschwächt, wobei diese Schwächung (Absorptionsrate) über einen oder mehrere Neutronenflußdetektoren gemessen wird.The measuring principle: The one generated in one or more neutron sources Neutron flux is weakened according to the boron concentration to be determined, this attenuation (absorption rate) via one or more neutron flux detectors is measured.

Die prinzipielle Funktionsweise kann aus dem Schwächungsgesetz abgeleitet werden: Neutronenfluß am Zählrohr Quell enneutronenfl uß makr. Absorptionsquerschnitt durchlaufener Weg Die Auflösung der Gleichung nach ! ergibt: mit wird mit Konzentration der Borkerne mikroskopischer AbsorptionsquerschnittThe basic functionality can be derived from the law of attenuation: Neutron flux at the counter tube Source neutron fl ux macr.
