FFR一次辅助系统阻塞计氮气冷却系统实验研究

EXPERIMENTAL INVESTIGATION OF NITROGEN GAS COOLING SYSTEM OF A PLUGGING METER IN THE PRIMARY AUXILIARY SYSTEM OF FFR

文章论证了我国第一座快堆FFR一次辅助系统阻塞计冷却系统的设计方案;并根据FFR一次辅助系统中阻塞计的设计参数、工作条件,实验给出了模拟不同阻塞计维持功率的情况下,氮气冷却系统的温度特性曲线;分析了此氮气冷却系统的热交换能力,实验证明该氮气冷却系统能够保证FFR一次辅助系统阻塞计以程控模式工作。

The design programme of nitrogen gas cooling system of a plugging meter in the primaryauxiliary system of the First Fast Reactor(FFR) in our country is proved in the paper. Accordingto the design parameter as well as the working condition of the plugging meter, the temperaturecharacteristic curves of the nitrogen gas cooling system are given experimentally under the condi-tion simulating various maintaining powers of the plugging meter, then the heat exchange capability of the system is analysed further, and a result is presented that the nitrogen gas cooling sys-tem can guarantee the plugging meter in the FFR primary auxiliary system work normally in theprogramme-controlled mode.
