Nuclear reactor power source with heat pipes bidirectionally inserted into reactor core

Abstract

The invention discloses a nuclear reactor power source with heat pipes bidirectionally inserted into a reactor core. The nuclear reactor power source comprises the reactor core, two groups of the heatpipes, two groups of shields and two groups of power generating parts. The two groups of the shields and the power generating parts are symmetrically arranged on two sides of the reactor core, one ends of the two groups of the heat pipes are inserted into the reactor core from two sides of the reactor core while the other ends are inserted into the two groups of the power generating parts respectively, the shields are arranged between the reactor core and the power generating parts, the heat pipes penetrate the shields, and the shields protect the power generating parts from radiation damagescaused by the reactor core. By adoption of a silent thermoelectric conversion technique, each power generating part comprises thermocouple conversion elements and cooling passages, wherein the thermocouple conversion elements and the cooling passages are arranged at intervals. One side of each thermocouple conversion element is heated by the corresponding heat pipe while the other side is cooledby a working medium in the corresponding cooling passage, so that temperature difference is formed on two sides of each thermocouple conversion element while thermoelectric potential is formed, and heat energy is converted into electric energy for multipurpose equipment and systems to use. By arrangement of the two groups of the power generating parts at two ends of the reactor core, the energy utilization rate is increased.

At present, the battery life of chemical power sources is very limited, and it is difficult for batteries and fuel cells to meet the needs of continuous use for several months or even years; internal combustion engines are supplemented by continuous fuel; Long lasting, but output power is too low

[0003] The heat pipe nuclear reactor power supply is one of the important candidates for flexible deployment, high power, and high endurance power supply. At present, the existing nuclear reactor power supply adopts the heat pipe cooling core, and the heat pipes are inserted from one side of the core. The space constraints are relatively strict, the number of thermoelectric conversion elements is usually small, and the output power and energy utilization of the power supply are low
