摘要

研制了一种用于核加热热离子转换器测试的装置,通过测量通过三个热桥的废热流,可以直接确定转换器的效率。1963年12月对该装置进行了50小时的桩内试验。该变流器由一个圆柱形钼发射极和一个铌集电极组成,电极间距为0.5 mm。发射极由(UZr)C燃料销的辐射加热。转换器工作45小时,大部分时间的电力输出在30到40瓦之间,效率高达11%。在这段时间结束时,转换器发生了永久性的局部短路。

Operating experience with an experimental nuclear heated thermionic converter

A rig has been developed for the testing of nuclear heated thermionic converters, which allows direct determination of the converter efficiency by measuring the waste heat flow through three thermal bridges. A 50 hr in-pile test of the device was performed in December, 1963. The converter consisted of a cylindrical molybdenum emitter and a niobium collector, with an electrode spacing of 0·5 mm. The emitter was heated by radiation from a (UZr)C fuel pin. The converter operated for 45 hr, with electrical power outputs between 30 and 40 W for most of the time, and with efficiencies of up to 11 per cent. At the end of this period a permanent partial short occurred in the converter.
