PRIORITY: US 83-468743 22 Feb 1983; US 83-468788 22 Feb 1983. DOCUMENT TYPE: Patent CA Section: 71 (Nuclear Technology) A nuclear fuel cylindrical pellet, which is at least partially coated with a burnable n absorber layer, is described. The n absorber layer, in turn, is provided with a directly combined hydrophobic cover layer. The substrate is essentially UO2 and the n absorber layer consists of a b-contg. material. A Nb-contg. underlayer (3-6 mm) is placed between the substrate and the n absorber layer which consists essentially of ZrB2 [12045-64-6]. The cover layer also consists chiefly of Nb.
