In order to meet seismic requirements, the five Motor Control Centers (MCCs) 670-E-10, 670-E-11, 670-E-12, 670-E-13, and 670-E-14 at the Advanced Test Reactor (ATR) (building Test Reactor Area [TRA]-670) need to be replaced. A test switch for the exhaust fan 670-HVE-18 would be installed, and the Variable Frequency Drive (VFD) 670-E-237, located next to the MCC 670-E-13, would be replaced. In addition, DC Panel 670-E-26 would be replaced with a new panel and new breakers, and the cabinet welded to it would be removed. The associated battery state-of-charge equipment would be moved to a separate seismically mounted enclosure. The Gas Control Loop Panel TF-E-2 would also be removed.
