Investigation of serviceability of rod carbide fuel pins on energy mode of high power of NEMF reactor

There were conducted post reactor material and science investigations of NRM (Nuclear Rocket Motor) standard fuel pins. There were used in complex test in ETC (Experimental Technological Channel) flowing technological channel of IV reactor on moving and energy modes of NEMF (Nuclear Energy Moving Facility) reactor. By comparing of condition of fuel pins which were tested in the course of different number of start-ups of IV-1 reactor on energy mode of high power (MHP) of NEMF reactor (number of start-ups on moving mode and on energy mode of low power is equal) there was determined the main factors of fuel pins serviceability on MHP.
