2 Post-Fukushima Drivers of Severe Accident Simulation FLEX NTTF RMRF B.5.b IRM ASME NSC HD simulator Desktop & full-scope Classroom Training Site drills/ exercises Safety analysis V&V

3 What Does the Industry Need? •  A single tool for: –  Safety analysis, emergency planning, technical support and training organizations –  Desktop, classroom, and full-scope simulators –  Multi-unit site scenarios from normal operations to EOP, SAMG and EDMG –  Ease of coupling with plant desired codes, such as dose •  An essential tool to meet regulatory requirements (e.g., NTTF) in post-Fukushima •  Reducing costs and risks with intuitive tool set to facilitate training, drills/exercises, analysis, and V&V

4 Tier 1 NTTF Recommendations •  2.1 - Seismic and flood hazard reevaluations •  2.3 - Seismic and flood walk downs •  4.1 - Station blackout (SBO) regulatory actions •  4.2 - Equipment covered under Title 10 of the Code of Federal Regulations (10 CFR) 50.54(hh)(2) •  5.1 - Reliable hardened vents for Mark I and Mark II containments •  7.1 - SFP instrumentation •  8 - Strengthening and integration of emergency operating procedures, severe accident management guidelines (SAMGs), and extensive damage mitigation guidelines •  9.3 - Emergency preparedness regulatory actions (staffing and communications)

5 Tier 3 NTTF Recommendations •  9.1/9.2 - Emergency preparedness (EP) enhancements for prolonged SBO and multiunit events (dependent on availability of critical skill sets) •  9.3 - ERDS capability (related to long-term evaluation Recommendation 10) •  10 - Additional EP topics for prolonged SBO and multi-unit events (long-term evaluation) •  11 - EP topics for decision making, radiation monitoring, and public education (long term evaluation) •  12.1 – Reactor oversight process modifications to reflect the recommended defense in-depth framework (dependent on recommendation 1) •  12.2 - Staff training on severe accidents and resident inspector training on SAMGs (dependent on recommendation 8)

6 Desktop Simulator Technology • PSA-HD (MAAP code) • Interactive GUI • Simulates most important systems & scenarios (RCS/ SG/Cont./Aux Blvd./SFP/Dose) Applications • Classroom training • Computer-based training (graphical and text procedures) • Engineering analysis

8 Full-Scope Simulator Technology • PSA-HD integrated in FSS • Enhanced simulator models as needed • Integrated EOPs, SAMGs & EDMGs Applications • Plant site drills and exercises involving TSC, OSC, EOF • Performance evaluation • Operator training • Realistic V&V and analysis

14 SBT in PSA-HD (SAMGs) SBT is a computer-based procedure that helps automate the SAMG to control the sequence of events in PSA-HD simulation.

16 PSA-HD Sample Configuration

17 Key Points •  Need to work with PRA and EP groups –  PRA group has MAAP Models (this is the standard) –  EP need these tools first and are developing responses to the Recommendations (Flex, SAMG) –  Model is important –  Then training •  May not need full-scope integration –  Start with single unit desktop (include Flex, etc.) –  Then expand to multi-unit/site model with fuel pool, etc. –  Use for validating updated procedures (demonstrate effectiveness) –  Expand interface for training of decision makers and stakeholders –  Then maybe integrate with full-scope simulator •  All desktop work is applicable so investment is not lost
