During performance of 2-SR-3.8.6.2(I-A) QUARTERLY CHECK FOR SHUTDOWN BOARD A BATTERY, the
DC subsystem was declared inoperable due to cell voltage not meeting Technical Specification (TS) acceptance criteria. Concurrently a second
DC subsystem was inoperable in support of scheduled maintenance activities. As a result of these subsystems being inoperable, Unit 2 entered TECHNICAL SPECIFICATION
LCO 3.0.3. at 0220 and commenced a shutdown at 0316. In accordance with
