The multiple siren activations were not related to any condition or event at Calvert Cliffs. The siren has experienced multiple losses of power as a result of the effects from heavy rain and wind associated with the passing of Tropical Storm Nicole. Each time the power had restored to the siren, it performed a full cycle test as opposed to the standard silent test.</br>County Officials were notified and are taking actions to communicate to Calvert County residents concerning the inadvertent siren actuation.</br>Site maintenance locally deactivated the siren at 0827 (EDT) and will further investigate the extent of issue with the siren once the Tropical Storm Nicole has passed. In response to deactivating the siren, Calvert County has implemented the back-up method of route alerting in the event that actual siren activation is required.</br>The NRC Resident Inspector has been informed of the activations.ctor has been informed of the activations. +
