2. Level sensor - Wikipedia

   en.wikipedia.org/wiki/Level_sensor

   The measuring minimum level starts from a complete covering of the measuring element near the head end of the level sensor. Filling levels below the level probe are not detected. Depending on the application and mounting height, it is therefore necessary to adjust the level in the evaluation unit to the respective mounting height with an offset ...

3. Nuclear reactor safety system - Wikipedia

   en.wikipedia.org/wiki/Nuclear_reactor_safety_system

   The High Pressure Coolant Injection (HPCI) System consists of a pump or pumps that have sufficient pressure to inject coolant into the reactor vessel while it is pressurized. It is designed to monitor the level of coolant in the reactor vessel and automatically inject coolant when the level drops below a threshold.

4. Loss-of-pressure-control accident - Wikipedia

   en.wikipedia.org/wiki/Loss-of-pressure-control...

   For whatever power level the reactor is currently operating at, a certain amount of enthalpy is present in the coolant. This enthalpy is proportional to temperature, therefore, the hotter the plant, the higher the pressure must be maintained to prevent boiling. When pressure drops to the saturation point, dryout in the coolant channels will occur.

5. Pressurizer (nuclear power) - Wikipedia

   en.wikipedia.org/wiki/Pressurizer_(nuclear_power)

   Since the reactor coolant system is completely flooded during normal operations, there is no point in monitoring coolant level in any of the other vessels. But early awareness of a reduction of coolant level (or a loss of coolant) is important to the safety of the reactor core. The pressurizer is deliberately located high in the reactor ...

   At 00:30 JST on 15 March, NHK ran a live press conference with TEPCO stating that the water level had sunk under the rods once again and pressure in the vessel was raised. The utility said that the hydrogen explosion at Unit 3 might have caused a glitch in the cooling system of Unit 2: Four out of five water pumps being used to cool the Unit 2 ...
