Summarizing of development results for reactor ceramic rod fuel elements of Nuclear Rocket Propulsion (NRP), Nuclear Power Propulsion Facility (NPPF), and Nuclear Hydrodynamical Propulsion Facility (NHPF)

In reactors both the space nuclear facilities (Nuclear Rocket Propulsion and Nuclear Power Propulsion Facility) and the ground-base Nuclear Hydrodynamical Facility of the same cell-free ceramic fuel elements type in the form double-blade involute rods with length 100 mm have been intended for apply. In the paper the summary of results on material testing for rod ceramic fuel elements condition after its trials in H2 gas-cooled channels of EWG-1M reactor and IRGIT reactor and N2 gas-cooled channels of EWG-1 reactor is presented
