** Though the Class 1E ( safety-related ) power bus is still powered by 3 highly-reliable emergency diesel generators that are safety related, an additional Plant Investment Protection power bus using a combustion gas turbine is located on-site to generate electricity to provide defense-in-depth against station blackout contingencies as well as to power important but non-safety critical systems in the event of a loss of offsite power.

** Though one division of the ECCS does not have high pressure flood ( HPCF ) capacities, there exists a steam-driven, safety-rated reactor core isolation cooling ( RCIC ) turbopump that is high-pressure rated and has extensive battery backup for its instrumentation and control systems, ensuring cooling is maintained even in the event of a full station blackout with failure of all 3 emergency diesel generators, the combustion gas turbine, primary battery backup, and the diesel firewater pumps.
