Summary

Description

Two of the fuel forms tested during the Rover/NERVA programs. The majority of experimental testing was performed using “graphite” fuel. It consisted of pyrocarbon coated uranium carbide (UC2) fuel particles which were dispersed in a graphite substrate. This fuel was operated at hydrogen exhaust temperatures as high as 2550 K. The second fuel form was a “composite” fuel which consisted of a UC-ZrC dispersion in the graphite substrate. Although the composite fuel received only limited nuclear testing in the Nuclear Furnace (NF-l), it also underwent extensive electrical furnace testing (~10 hours at 2750 K with 64 temperature cycles) which demonstrated the potential to provide hydrogen exhaust temperatures and equivalent Isp values of ~2700 K and 900 s, respectively.
