Hara water is deposited into the h:Cr reactor pressure vessel. The spray range of head spray water is shown by the broken line in Figure 2. The head spray water hits the steam dryer foot together with the steam condensed water in the reactor pressure vessel, and bounces off the inner wall of the reactor pressure vessel. I can't imagine falling along it.

ある。Then, a water film is formed in front of the gas phase water level instrumentation nozzle 11. Additionally, during normal operation, the steam in the reactor pressure vessel condenses, but a small portion of it may fall along the inner wall of the reactor pressure vessel, forming a water film. . As a result, water level measurement in the reactor poses no problem in terms of reactor operation and safety, but there is a risk that some errors may occur.
