On January 16, the comprehensive tests of the New Safe Confinement radiation monitoring system were started. Emergency situations are simulated during the tests and response of specific systems on them is checked.
Leading engineer of the Radiation Safety Shop Yevhen Stromko provides comments regarding this activity: "Tests are carried out as close as possible to the normal operating conditions of the facility. We give alarms to the safety controller, which sends signals to NSC technological systems. For example, an alarm in the ventilation system should lead to the closure of the door, shut-off of air ducts, which in turn will activate the air filtration systems. A sound and light alarm is generated".
During three days, from January 16 to January 18, similar tests were carried out in all zones of NSC. The first zone includes the main space of NSC (space under the arch) and a unit of liquid radioactive waste (hereinafter: RAW). The second zone represents the premises where radioactive waste will be managed. The third zone is intended for the personnel, this is the cleanest zone in terms of radiation safety.
