It’s just a test: Koeberg to blast nuclear alarm at full volume this week

KOEBERG TO TEST SIRENS

The annual full volume test of the Koeberg Nuclear Power Station Public Warning System, which includes sirens and a public address system, is expected to be performed between 10:00 and 12:00 on Tuesday.

“The duration of the test is approximately fifteen minutes per siren and consists of a voice clip indicating that a test is being performed, and the sound of the nuclear alarm (slow rising tone),” said Eskom.

The national power utility added that retesting will take place on individual sirens on Wednesday and Thursday, if necessary.

WARNING SYSTEM INSTALLED 16KM AROUND KOEBERG

Koeberg’s warning system is installed in a 16-kilometre radius around the Nuclear Power Station – the Urgent Protective Action Zone (UPZ). The system is meant to warn residents in the event of an unlikely emergency at the station, said Eskom.

“Koeberg uses a radio system, which controls the communication between the control centres and each individual siren.

“Communication checks are performed daily and any sirens not communicating with the control station are repaired as soon as possible,” said the power utility.

Silent tests that check the functionality of the siren amplifiers are conducted on a weekly basis.

Eskom is legally required to perform a full-volume test to check that the sirens are fully audible on an annual basis.
