Beschreibung
Zusammenfassung:	Un montaje de combustible nuclear que comprende: una disposición espaciada de una pluralidad de elementos combustibles nucleares tubulares alargados que se extienden axialmente que tienen un primer y un segundo extremos cerrados y que encapsulan un material fisionable axialmente a lo largo de al menos una porción de un volumen interior del mismo y un exterior de al menos uno de los elementos combustibles que comprende una vaina que se extiende substancialmente de manera axial entre el primer y segundo extremos cerrados, y una textura superficial de dicha vaina que varía axialmente de acuerdo con un patrón prescrito a lo largo de la longitud axial de dicha vaina entre el primer y segundo extremos cerrados. A crud-resistant nuclear fuel element cladding in which the axial locations that experience nucleate boiling during reactor full power operation are highly polished so that the maximum size of any surface defect on the highly polished surface is approximately 0.1 microns. The remainder of the cladding surface remains unpolished so that crud is more evenly redistributed over the entire fuel cladding surface to limit the thickness of the crud that is formed to less than 35 microns.
