SHORT-TERM FAST FLUX (EBR-II) IRRADIATION OF PuO$sub 2$--UO$sub 2$ FUEL PINS.

1000-MWe LMFBR FOLLOW-ON STUDY. TASK II AND III FINAL REPORT. VOLUME 5. PARAMETRIC STUDIES.

“…In this study, as in the other heat transport system parameter studies, the reactor core and the steam cycle conditions (with one exception- [1][2][3][4][5] discussed below) were held constant. Thus, the optimum temperatu re depends primarily on the relative costs of equipmen t in the primary and intermediate systems.…”

Status and Evaluation of Mixed Oxide Fuel.

“…(7) 2) No clear picture of the effect of impurities, particularly iron at the 1500 to 3000 ppm level has yet emerged. (7) 3) Localized, oxide-type reaction was observed on the inner surface of FCR fuel pins, and the effect was attributed to attack by impurities, as yet unidentified, in the fuelo (15) B.
