障を発生させないようにしている。Conventionally, wire mesh strainers have been installed in various types of equipment to collect water scale and oxides (crud) generated in piping and water storage tanks during operation, and to prevent damage to bearings due to water scale and cladding entering the equipment. This prevents malfunctions such as wear and dust buildup in the valves.

。When the strainer becomes clogged, the pressure loss in the strainer increases and the water flow rate decreases. Furthermore, excessive pressure loss may cause deformation and damage to the strainer. To prevent this, workers regularly remove and clean the strainers, but this can contaminate the building and expose workers to radiation.
