Description

The improvement of operational safety and reduction of fuel cycle costs are the motivating forces in the development of new ABB fuel element concepts such as the SVEA concept in 1981. The SVEA 96/100 design opens up the possibility to improve the operational safety with a fuel coolant interaction proof fuel element and the possibility to increase the burnup. These aims also apply to PWR fuel elements. With the safety standard maintained, the introduction of solid Zircaloy spacers, the axial distribution of gadolinium and the development of a corrosion resistant fuel can, mainly economic aspects are concerned.

Abstract (German)

Die Verbesserung der betrieblichen Sicherheit sowie der Brennstoffzykluskosten sind die treibenden Kraefte bei der Entwicklung neuer ABB Brennelementkonzepte, wie die Einfuehrung des SVEA Konzeptes im Jahre 1981 zeigte. Mit dem SVEA 96/100 Design eroeffnet sich die Moeglichkeit zur Verbesserung der betrieblichen Sicherheit durch ein Brennstoff-Kuehlmittel-Wechselwirkung-festes Brennelement wie auch die Moeglichkeit zur Erhoehung des Abbrandes. Auch fuer die DWR-Brennelemente gelten diese Zielsetzungen, wobei unter Beibehaltung des Sicherheitsstandes durch Einfuehrung von Voll-Zirkaloy Abstandshaltern, des axial abgestuften Gadoliniums und die Entwicklung eines korrosionsbestaendigen Huellrohres insbesondere wirtschaftliche Aspekte angesprochen sind.
