Abstract

The results of experimental studies of the applicability of the float-discrete method for measuring the level of a heavy liquid-metal coolant (HLMC) using sealed magnetically controlled contacts as a sensitive element are presented. These contacts register the coolant level in the field of a permanent magnet located on the surface of a heavy liquid-metal coolant. The performance of such a level sensor was studied using a control tank with a lead-bismuth coolant under conditions close to natural ones. This method is simple, but its main problem is maintaining the integrity of sealed magnetically controlled contacts when exposed to high temperatures. The experiments were carried out using a float-discrete level sensor prototype on a high-temperature stand with a lead-bismuth coolant. The data collected during the processing of the results confirm with reliable accuracy the applicability of the float-discrete method for monitoring the level of a heavy liquid-metal coolant. An HLMC level measuring device operating according to this method makes it possible to monitor the level in tanks while maintaining the tightness of the circuit. Due to this, it is possible to abandon the currently common methods for determining the level of HLMC using electric contact level sensors in which the sealing of the circuit is impossible. This device can be used on various experimental stands with liquid-metal coolants as well as in reactor plants and accelerator-controlled systems in the temperature range of 210–230°C, for example MYRRHA. To ensure the operability of the level transmitter at higher temperatures, it is necessary to upgrade the reed switch cooling system.

浮动离散法测量重金属液体冷却剂液位的实验研究
摘要 介绍了使用密封磁控触点作为敏感元件测量重液态金属冷却剂(HLMC)液位的浮子离散法适用性的实验研究结果。这些触点在位于重液态金属冷却剂表面的永久磁铁磁场中记录冷却剂液位。在接近自然条件下,使用装有铅铋冷却剂的控制槽对这种液位传感器的性能进行了研究。这种方法很简单,但其主要问题是在高温条件下保持密封磁控触点的完整性。实验是在高温台架和铅铋冷却液中使用浮子离散液位传感器原型进行的。结果处理过程中收集的数据以可靠的精度证实了浮子离散法在监测重金属液态冷却剂液位方面的适用性。根据这种方法运行的 HLMC 液位测量装置可以在保持回路密封性的同时监测储罐中的液位。因此,可以放弃目前常用的使用电接触式液位传感器来确定 HLMC 液位的方法,因为这种方法无法保证回路的密封性。该装置可用于各种使用液态金属冷却剂的实验台,也可用于温度范围在 210-230°C 的反应堆厂房和加速器控制系统,例如 MYRRHA。为确保液位变送器在更高温度下的可操作性,有必要对干簧管冷却系统进行升级。
