FIELD: power supply.
SUBSTANCE: invention relates to power supply and protection of space vehicles (SC) against ionizing radiations. A nuclear power plant (NPP) of the spacecraft comprises a nuclear reactor remote from the spacecraft by means of a folding frame, and a positively charged unfolding protective shield installed between the reactor and the SC service system module. On the screen and on the module there are thermal emission electron sources performing neutralization of the medium around the spacecraft.
EFFECT: technical result consists in reduction of effect of ionized particles and activated nuclei of gas-dust environment of spacecraft, causing induced radiation, on functioning of onboard equipment of spacecraft.
