10MW高温气冷实验堆（HTR-10）于2000年底在中国建成并实现临界，是一项重大的科研成果。它采用包覆颗粒燃料构成的球形燃料元件，堆芯有2.7万个燃料元件组成，四周由石墨反射层堆砌而成。氦冷却剂出口温度可达700℃。HTR-10具有非能动的安全特性。采用非能动余热载出的先进设计概念，可保证在任何事故工况下排除堆芯燃料熔化的可能性。该文介绍了10MW高温气冷实验堆的燃料元件、设计特点和安全特性。

The 10 MW high temperature gas-cooled reactor (HTR-10) reachedcritical in the end of 2 000 in China. The core of HTR-10 is composed of 27 000 graphite fuel elements formed with coated particles and surrounded by the blocks of graphite reflector. The outlet temperature of helium coolant could reach 700 ℃. The design of passive removal of decay heat by nature mechanism of heat radiation and conversion is adopted in HTR-10. It means that HTR-10 has the passive safety characteristics which could prevent the occurrence of core melt during any severe accidents. The paper describes the features of fuel element, reactor design and its safety.
