Should nuclear scales or electronic scales be used for coking coal blending?

Electronic scales require a lot of maintenance work, while nuclear scales have a low failure rate; however, once a problem occurs, it is difficult to resolve. I invite experts to share their opinions and discuss together the advantages, disadvantages, and solutions.
Our company uses electronic scales, and no major problems have occurred since they were put into use, so they are fine.
Our company also uses electronic scales, but sometimes there is underweight reading. Maintenance is straightforward; the workload isn’t very heavy
Our company also uses electronic scales; we have never used nuclear scales.
It seems that Bayi Steel uses nuclear scales; friends who work there say the performance is quite good. However, our factory uses electronic scales.
We use electronic scales from Chengdu Guanghua Electrical Appliance; they perform well, require little maintenance. The sensors are of American manufacture, while the display system is Japanese.
Don’t use a nuclear scale; there are too many various fees, appraisal costs, and health check-up fees – it’s too much and too troublesome.
The coking plant of Wuhan Iron and Steel Group uses nuclear scales!
I don’t think nuclear weight scales are very accurate; they require calibration using actual samples. When there are significant differences in parameters such as ash content and moisture level between the coal used for calibration and the coal actually used, this affects the absorption of radiation and thus impacts the accuracy of measurement. Therefore, I believe nuclear weight scales are suitable for coking plants where the coal supply is stable. If the coal source is unstable and varied, it’s better to use electronic weight scales, which can generally keep the error within 1%, and their accuracy is ensured as long as they are calibrated regularly, regardless of the quality of the coal
There are many electronic scales; I’ve never heard of nuclear scales. Could you explain their working principle in detail?
