Bellefonte MCR/HFE

Background

Control room designed and built in early 1980s Bailey equipment installed in main control room July 14, 2011

Bellefonte MCR/HFE Phase 0 Meeting 6

Bellefonte MCR/HFE Background (continued)

Detailed control room design review performed in early 1980s to address TMI action item I.D.1 795 HEDs identified with 425 HED still to be resolved Some legacy issues, documented as HEDs, remain to be resolved July 14, 2011

Bellefonte MCR/HFE Background (continued)

July 14, 2011

Bellefonte MCR/HFE Phase 0 Meeting 8

Bellefonte MCR/HFE Background (continued)

• MCR/HFE modernization will address:

- Unresolved HEDs that required significant modifications to correct

- Obsolescence of existing controls and indication

• Modernization of balance of plant I&C offered opportunity for use of integrated controls, displays, and alarms

- Significantly better than the relocation, paint, tape, and label fixes previously envisioned July 14, 2011

Bellefonte MCR/HFE Phase 0 Meeting 9

Conceptual Plan for Modern Bellefonte Control Room

• Consolidate number of panels with safety related components

• Normal control from sitting work stations

• Safety-related control from standing work stations

• Safety-related work stations set on each side of unit supervisor desk July 14, 2011

Bellefonte MCR/HFE Phase 0 Meeting 10 Conceptual Plan for Modern Bellefonte Control Room (continued)

• Shift turnover/briefing room and shift manager office added

• Use of mosaic technology for safety-related work stations

- RO2 controls turbine and BOP from non-safety Controls July 14, 2011

Bellefonte MCR/HFE Phase 0 Meeting 14 Conceptual Plan for Operation (continued)

• General Concept of Operations -

Emergency

Response

- RO1 performs safety-related actions of EOPs from safety panel (and EDG panel, if required)

- RO2 performs supporting EOP actions from non-safety panels July 14, 2011

Bellefonte MCR/HFE Phase 0 Meeting 15 Conceptual Plan for Operation (continued)

• General Concept of Operations - Loss of Offsite Power

- RO1 performs safety-related actions of AOPs from safety panel

- RO2 recovers electrical power at EDG panel and directs field operations July 14, 2011

Bellefonte MCR/HFE Phase 0 Meeting 16 Conceptual Plan for Operation (continued)

• General Concept of Operations - High Workload Surveillance Testing

- RO1 controls reactivity and NSSS from non-safety controls

- RO2 controls turbine and BOP from non-safety controls

- RO3 performs surveillance at safety panel or EDG panel, as required July 14, 2011

Bellefonte MCR/HFE Phase 0 Meeting 17 HFE Process

• Bellefonte Human Factors Engineering Plan

- Integrated plan based on NUREG 0700 and NUREG 0711
