新型海洋静默式热管反应堆的概念设计

Conceptual Design of Nuclear Silent Thermal-Eletrical Reactor

本文提出一种能够提供100 kWe电功率的新型海洋静默式热管反应堆(NUSTER-100)电源系统,可为无人水下潜航器提供低噪音、长寿期的电力供应。该电源系统采用双层壳体布置,主要由反应堆堆芯、热管、屏蔽体、温差发电器热电转换系统和螺旋式余热排出系统等子系统组成。在反应堆堆芯中,UO;燃料棒、慢化棒和钠热管矩形排列布置,以及热管从堆芯双端伸出,其冷凝段与温差发电器相连,实现热电转换。

A new conceptual design of a 100 kWe level nuclear silent thermal-electrical reactor(NUSTER-100)power system adopted to provide low-noise and long-life power supply for unmanned underwater vehicles is developed.This system adopts a double-layer shell layout, mainly composed of the reactor core, heat pipe, shielding body,thermoelectric power generation thermoelectric conversion system and spiral waste heat exhaust system and other subsystems. In the reactor core, UO;fuel rods, moderator rods, and sodium heat pipes are arranged in a rectangular arrangement;the heat pipes extend from both ends of the core,and the condensing section is connected with a thermoelectric generator to realize thermoelectric conversion.
