METHOD FOR OPERATION OF DUAL-MODE THERMIONIC REACTOR-CONVERTER FOR NUCLEAR POWER PLANT Russian patent published in 2020 - IPC G21D1/00 H01J45/00 

FIELD: nuclear equipment.

SUBSTANCE: invention relates to a method of operating a thermionic converter reactor (TCR) with emitter shells of EGC from a hardened monocrystalline molybdenum-based alloy, which includes operation of TCR in forced mode at constant heat power with subsequent output to nominal mode. During operation at nominal mode continuous monitoring of thermal and electric power of reactor is carried out and in process of failure of separate most energy-intensive electric generating elements of thermoemission electric generating channels EGC and electric power drop on ≥50 W using the automatic control system using the inactive reserve for utilization of heat energy at nominal mode, increasing the thermal power of the reactor from the condition of maintaining constant value of output electric power of the rated mode in the resource. Increase of heat power is carried out within the limits of design heat power value of the reactor at forced and nominal operation modes.

EFFECT: technical result is achievement of long (7–10 years) TCR resource with built-in into EGC reactor core with emitter shells from reinforced monocrystalline molybdenum-based alloy while maintaining constant output electric power at nominal resource-determining mode of EGC operation.
