For example, when the RPV takes over the inner wall inspection, the difference between the reference sensitivity adjusted by the concave interview block and the flat test block is nearly 15dB.
For example, when RPV takes over the inner wall detection, the baseline sensitivity of the concave interview block and the flat interview block adjustment is close to 15dB.
For example, when testing the inner wall of RPV nozzle, the benchmark sensitivity difference between concave test block and plane test block is close to 15dB.<BR>
