The working capacity and operating stability of multi- and single-cell electricity generating channels of the nuclear power systems TOPAZ-1 and -2 are largely determined by the emission properties of the emitter and collector electrodes. The emission properties and elemental composition of the electrode surfaces of single-cell EGC E-16MO, which exceeded their lifetimes in the experimental systems YA-24 and -81, which are prototypes of the Enisei space nuclear power system, separate EGCs in the L channels, and in thermal stands, are determined. The previously performed comprehensive investigation of various processes on the electrode surfaces of EGC, and the database collected, made it possible to perform a statistical analysis of the results and to estimate the lifetime stability of the electrodes on the basis of the emission properties up to 3 yr with 95% probability. 8 figures, 4 tables, 15 references.
