The Integrated Human Event Analysis System (IDHEAS) Program Introduction Sean E. Peters Advisory Committee on Reactor Safeguards Reliability and PRA Subcommittee Meeting September 23, 2020
Why are we here?
SRM-M061020 The Committee should work with the staff and external stakeholders to evaluate the different Human Reliability models in an effort to propose either a single model for the agency to use or guidance on which model(s) should to be used in specific circumstances.

- PRA Policy Statement " (60 FR 42622) - The use of PRA technology should be increased in all regulatory matters to the extent supported by the state of the art in PRA methods and data, and in a manner that complements the NRC's deterministic approach and supports the NRC's traditional defense-in-depth philosophy.

IDHEAS Development Process
- US and International Benchmarking Projects -
determined existing methods strengths and weaknesses
- Cognitive Basis Report
- Extensive Literature Review, Scientific Basis for Structure
- IDHEAS at-Power
- Industry/NRC Collaboration - goal of reducing variability
- Fukushima 5
Development Process (cont.)
- IDHEAS-G
- Guidance for developing application-specific HRA methods or tools
- Framework to generalize and integrate human error data
- Structure to analyze human events and identify human failures and root causes
- IDHEAS-ECA
- Built from IDHEAS-G to handle all NRC applications
- Can be used for in/ex control room activities and other nuclear/non-nuclear domains (human centered method)
- Quantification model and software tool included 6
Development Process (cont.)
- IDHEAS-Data
- Data basis for IDHEAS quantification
- Constantly evolving and tied to NRC data collection activities
- Scenario Authoring, Characterization, and Debriefing Application - SACADA
- NRCs Human Performance Test Facility
- Halden 7
IDHEAS Reviews
- IDHEAS-G
- Multiple ACRS Subcommittee reviews
- 2 external peer reviews, 1 internal peer review
- Tested on: Fukushima, US Benchmarking Events, Fuel Cycle Facility Events
- IDHEAS-ECA
- Tested on FLEX Scenarios (NRC and industry studies), ASP and SDP Events
- Currently taking user comments to incorporate into revised report/tool
- IDHEAS-DATA
- Data review (underway), peer review possible thereafter
- Plans for regular updates 8

IDHEAS Future Work
- IDHEAS-G - Publication
- IDHEAS-ECA - Refinement/Rollout
- Dependency
- Recovery
- Timing
- Integrate with SAPHIRE/SPAR Models
- Publication of revision

- Security (Physical and Cyber) 11
Path Forward for the ACRS
- Complete/Practical HRA Method
- Improvement to the current state of practice at the NRC
- Human-centered, scientific and data-based
- Program for continuous updates based on user feedback and data
- Can be applied to all NRC applications
- Closure of SRM-M061020?
