| Abstract: | Characterized by its high specific impulse and large thrust, Nuclear Thermal Propulsion (NTP) shows wide applications in deep space explorations and interplanetary cargo missions. Various ground tests are required to develop NTP technology. This paper first reviews technology development of NTP ground tests of the United States and Russia. Then, based on a small nuclear thermal rocket concept (CERMET-SNRE), technical options for some key tests such as non-nuclear test of fuel element, irradiation test of fuel element and NTP engine integration test are studied. Finally, some suggestions for the technology development of NTP ground tests are proposed. |
