Development of a recycle fuel for the HTGR

Abstract

A Weak-Acid Resin-derived (WAR) kernel has been selected as the new reference recycle fuel, and the irradiation program reoriented toward establishing optimum specifications. The loaded resin is carbonized to a dispersion of UO$sub 2$ in carbon at about 1200$sup 0$C. Continued heating to higher temperatures can convert the UO$sub 2$ to carbide, completely at 1800$sup 0$C. Performance of WAR fuels at three levels of conversion is compared. 5 references (auth
