Description
In order to manufacture boric acid solution for reactor commissioning, the heated water is divided into a main and subsidiary flow, and the total amount of the salt is added to the subsidiary flow. Mixing of the main flow with the salt-containing subsidiary flow takes place on a mixing column. Undissolved salt is removed in a hydro-cyclotron. Preheating of the water takes place in a recuperator heat exchanger and a through boiler provides the final temperatures. (HK)

Zur Herstellung der Borsaeureloesung bei der Inbetriebnahme des Reaktors wird das erwaermte Wasser in einem Haupt- und Nebenstrom aufgeteilt und die gesamte Salzmenge dem Nebenstrom beigegeben. Die Vermischung von Hauptstrom mit salzigem Nebenstrom erfolgt in einer Mischerkolonne. Ungeloeste Salze entfernt ein Hydrozyklotron. Die Vorwaermung des Wassers nimmt ein Rekuperativwaermetauscher vor und im Durchlauferhitzer stellt die Endtemperatur her. (HK)Files
