Air Cleaning Unit Test

1. Test Inspection of Nuclear Air Cleaning System

The air cleaning system is used for the purpose of controlling the discharge of pollutants by filtering radioactive substances in the air inside the facility, protecting workers in the facility, and preventing public exposure. In order to perform the final role of safety in accordance with the Nuclear Act, the safety shall be ensured by objectively and reliably performing acceptance tests (verification tests) and regular/non-regular performance maintenance tests during manufacturing and installation.
