Normal feedwater was lost to the two boilers (#2 and #3) that were in service due to plugged aerators. Apparent damage to the boilers resulted when feedwater was restored through a bypass line to the uncovered tubes. As of 10:00 a.m., the plant was attempting to place the #1 boiler in service, which was out for minor maintenance. The plant was also monitoring cascade conditions and taking actions, as necessary, to prevent process gas freeze out. The facility has convened the Operational Assessment Team to review the recovery actions for steam restoration. Regional Action: NRC Region III will continue to monitor the situation.
