Safety aspects related to burnup increase and mixed oxide fuel
Creators
Description
The dominant factor presently limiting the fuel burnup is the response of the cladding hulls. To maintain the excellent record of very low fuel failure rates for increased burnups further technical development is underway and necessary. In the nuclear fuel cycle increased burnups lead to a remarkable reduction of spent fuel arisings and corresponding economic savings. Thermal recycling of plutonium presently provides an opportunity to reduce the rising accumulation of plutunium in a situation where there is no demand for this fissile material in Fast Breeder Reactors.

Abstract (German)
Der gegenwaertig den erreichbaren Abbrand begrenzende Faktor liegt im Verhalten des Brennstabhuellrohrs. Hierzu laeuft Entwicklungsarbeit, damit auch bei hoeheren Abbraenden die niedrige erreichte Versagensrate der Brennstaebe eingehalten werden kann. Im nuklearen Brennstoffkreislauf fuehren hoehere Abbraende zu einer bemerkenswerten Reduzierung des Anfalls an abgebrannten Brennelementen und einer entsprechenden besseren Wirtschaftlichkeit. Durch die thermische Rezyklierung von Plutonium kann die Anhaeufung dieses Spaltstoffs reduziert werden, zumal hierfuer gegenwaertig keine Einsatmoeglichkeit als Brennstoff in Schnellen Brutreaktoren besteht.
