Systems for Measuring BN-800 Sodium Flow

详细

The presented systems are intended for measuring the sodium flow through the main circulation pumps in the first loop and FA in BN-800. The systems are identical in terms of structure and contain two electromagnetic and one correlation channel. A comparative analysis of the measured and computed flows through the GTsN-1 bypass flowmeters shows that 85% of the experimental points deviate from the computed relation by not more than ±5%. The deviations of the experimental data from the calculation of the flow through all FA in the core do not exceed, on average, 2% for different groups of FA.
