Early-in-life performance of short rod duplex pellet screening (D-1) test (AWBA Development Program)
This report evaluates the early-in-life irradiation performance of the D-1 test. The D-1 test is a screening test of the duplex pellet prebreeder reactor fuel concept consisting of a cylindrical thoria pellet surrounded by an annulus containing urania enriched in uranium-235. The design of the test, which includes duplex pellet annuli of three different compositions (UO/sub 2/, UO/sub 2/-ZrO/sub 2/, and UO/sub 2/-ZrO/sub 2/-CaO), is described and results of nondestructive and destructive examinations after operation at 13 to 15 kW/ft for 32.6 days are presented. It is concluded that there are no deficiencies in the early-in-life performance of the duplex pellets. The UO/sub 2/-ZrO/sub 2/ annuli show greater densification than the other two fuel types; however, this does not result in detrimental performance. On the basis of these findings, test irradiation was continued.
