TVA, AREVA
- Desmond Raymond - AREVA HFE Manager
- Jim Hawks - TVA Oversight
- Jerry Mauck - TVA Oversight July 14, 2011 Bellefonte MCR/HFE Phase 0 Meeting 3
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 4
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 Phase 0 Meeting 6
Bellefonte MCR/HFE Background (continued)
July 14, 2011 Bellefonte MCR/HFE Phase 0 Meeting 7
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 8
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 9
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
- Use of group-view panel for plant overview monitoring safety and crew situational awareness July 14, 2011 Bellefonte MCR/HFE Phase 0 Meeting 10
Conceptual Control Room Layout July 14, 2011 Bellefonte MCR/HFE Phase 0 Meeting 11
Conceptual Control Room Layout July 14, 2011 Bellefonte MCR/HFE Phase 0 Meeting 12
Conceptual Plan for Operation
- General Concept of Operations -
Normal Operation
- RO1 controls reactivity and NSSS from non-safety controls
- RO2 controls turbine and BOP from non-safety Controls July 14, 2011 Bellefonte MCR/HFE Phase 0 Meeting 13
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 14
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 15
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 16
HFE Process Operating PRA/HRA Experience Review Risk-Significant Human Actions
- Bellefonte Human Requirements Management Factors Engineering Plan FRA/FA Design Assessment
- Integrated plan based on Task Analysis NUREG 0700 and NUREG 0711 DESIGN
- Uses previous CRDR HED Training Program Development HSI Design Procedure Development work as operating experience input HFE V&V
- Builds on industry experience from B&W Design Implementation operating plants Human Performance Monitoring July 14, 2011 Bellefonte MCR/HFE Phase 0 Meeting 17
