Description

Heating rods have been tested under cold conditions without pressure and under working conditions. The characteristic of defects and measures to assure the quality have been found. Two types of heating rods, 'Siemens Makrorohrheizkoerper' and 'Philips Rod Heater', have been tested. Both types are qualified as heating rods for pressurizers after considering the requirements corresponding to the results of the tests. In the future, heating rods of the type 'Rod Heater' will be used; this type has rendered possible the simplification of the pressurizer design because of its working assurance. (orig.)

Abstract (German)

Untersucht wurden Heizstaebe im kalten drucklosen und im Betriebszustand, Schadensursachen und Schadensverlaeufe wurden erkannt und entsprechende Massnahmen zur Qualitaetssicherung getroffen. Zwei Heizstabtypen - Siemens Makrorohrheizkoerper und Philips Rod Heater - wurden getestet. Beiden Typen sind nach Beruecksichtigung der aus den Pruefungen entstandenen Forderungen als Druckhalterheizstaebe geeignet. In Zukunft sollen Staebe des Typs 'Rod Heater' eingesetzt werden, die durch ihre Betriebssicherheit wesentliche Vereinfachungen des Druckhalters ermoeglichen. (orig.)
