| 摘要 |
The present invention relates to a water level monitoring system for a spent fuel storage tank in a nuclear power plate. More specifically, the water level monitoring system for the spent fuel storage tank in the nuclear power plant comprises a detection probe for detecting a level change in a boracic acid solution by being installed in the spent fuel storage tank; and an optical time-domain reflectometer (OTDR) for measuring a water level in the spent fuel storage tank by being connected to the detection probe through optical fiber and receiving reflected light reflected from the end of the detection probe through optical fiber. |
