主氦循环风机是10MW高温气冷实验堆(HTR-10)的关键设备，在250℃、3.OMPa的氦气气氛下将反应堆的热能输送到蒸汽发生器：针对反应堆的特殊要求，主氦循环风机的设计包括总体结构、叶轮型式、冷却系统、轴承、测量仪表、电气贯穿件和隔断阀。对设计制造的主氦循环风机进行了出厂试验和安装后的冷、热态性能试验。按照反应堆的调试要求，主氦循环风机随反应堆的调试进行了初步运行。试验和运行结果表明。主氦循环风机达到了设计要求，能满足HTR-10的运行要求。

由于高温气冷堆主氦风机特殊的使用环境，对其轴承提出了苛刻的要求。已建成或计划中的高温气冷堆的主氦风机具有不同形式的轴承。包括水润滑轴承、油润滑轴承、脂润滑轴承、气体轴承和磁悬浮轴承等。本文对此进行了对比。磁悬浮轴承具有明显的选用前景，有些问题有待解决，正进行深入研究。

The helium circulator is a key component of the 10MW high temperature gas. cooled reactor (HTR-10). which assures the thermal energy transfer from the reactor core to the steam generator and operates at 3.0MPa. 250C helium condition. At the rated condition, the mass flow rate iS 4.32 kg S-1 and the pressure rise can reach 51.7kPa at the rotational speed of 5000 rpm. In fact, the pressure rise required for the HTR-10 is only 14.7kPa with a rotational speed of 3052 rpm. Thus, the layout of the blower contains a considerable margin. This paper presents the design procedures of the circulator during its development. Test results both in the factory and in the HTR-10 are given. Furthermore, the circulator design features and aerodynamic performance are highlighted.

A small absorbmr ball system is the second shutdown system of the 10 MW High Temperature Gas-cooled Reactor-Test Module. When the control rod system is out of operation. the small absorber ball system is required to emergently shut down the reactor by means of boron carbide balls totally dropping into channels in the side reflector by gravity. Before the reactor re-operates, these small absorber balls must be conveyed from channels in the side refector back to the ball storage vessels below the head of reactor pressure vessel by a pneumatic conveying process. Detailed design of the small absorber ball system was caMed out. and all the components were manufactured. In order to check the performances of the smalI absorber ball system. a pneumatic conveying experiment and a hot test were carried out in the laboratory, and also a pre-operation of the small absorber ball system was verified on the reactor site at room temperature. Test data of the sma]I absorber ball system show that all the parameters, including time of ball dropping, time of ball conveying back, indication of ball level in the ball storage vessel. gas flowrate. and valve operation states. are acceptable and reasonable. The small absorber ball system has been shown to be capable Of performing satisfactorlly at operating temperattures of the reactor.
