The ERV failed to actuate during surveillance testing, which was found to be caused by internal binding of the valve actuator due to the improper rebuild of the actuator prior to being installed on April 7, 2020.

On August 18, 2022, Brian Wake verbally discussed CEG's decision to submit a written response to the preliminary White finding with the NRC. This letter confirms that CEG intends to respond to the preliminary White finding with a docketed letter. CEG's written response will be submitted no later than September 16, 2022, which is within the 40 days required in the referenced letter.
There are no regulatory commitments contained in this letter.
