Crud-resistant nuclear fuel cladding

   
   

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.

Un revestimiento nuclear crud-resistente del elemento combustible en el cual las localizaciones axiales que experimentan el nucleate que hierve durante la operación de los plenos poderes del reactor se pulen altamente de modo que el tamaño máximo de cualquier defecto superficial en la superficie altamente pulida sea aproximadamente 0.1 micrón. El resto de la superficie del revestimiento sigue siendo sin pulir para redistribuir el crud más uniformemente sobre la superficie entera del revestimiento del combustible para limitar el grueso del crud que se forma menos de 35 micrones.
