A comprehensive hot cell examination has been performed on 12 17x17 fuel rods irradiated in the Surry reactors. Four of the fuel rods had achieved an average burnup of 29,600 MWD/MTU over three cycles of irradiation in the demonstration assembly RD-2 which was irradiated in Surry Unit 2. Six of the fuel rods were irradiated over four cycles in the RD-2 assembly to an average burnup of 44,000 MWD/MTU. The remaining two rods examined in the program were of a lower initial enrichment and had substantially different power histories. These latter rods were irradiated in the Surry Unit 1 reactor in the RD-1 demonstration assembly for the first two cycles, after which they were transferred to the RD-2 assembly. The average burnup of these two rods over four cycles was 39,800 MWD/MTU. Based upon the hot cell examination, the Surry fuel rods showed no evidence of any significant materials limitations in achieving extended burnups to about 45,000 MWD/MTU.
