The autotransformer supports interconnectivity between each side of the switchyard and is not required for switchyard operation. There was no work in progress on the associated autotransformer at the time of the event. The autotransformer and the switchyard are outside the protected area approximately one mile away. The fire was contained to the autotransformer only. The fault has been electrically isolated and there was no effect on either MNS [McGuire Nuclear Site] Unit 1 or Unit 2 operations. No personnel were injured as a result of the fire. Local Fire Department responded and has contained the fire. MNS fire brigade leader along with switchyard maintenance have confirmed no effects to the MNS bus lines, power availability, or the ability for the site to generate power.
