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.

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 Event - March 2011 6
 
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 7
 
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 Reactor Project 8
 
IDHEAS Reviews
* IDHEAS-G
  - Multiple ACRS Subcommittee reviews
  - 3 external peer reviews, 2 internal peer reviews
  - Used on: Fukushima, US Benchmarking Events, Fuel Cycle Facility Events
* IDHEAS-ECA
  - Used 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)
  - Plans for regular updates 9
 
Future of the Integrated Human Event Analysis System (IDHEAS)
Program Sean E. Peters, Chief Human Factors and Reliability Branch Office of Nuclear Regulatory Research April 8, 2021
 
IDHEAS Future Work
* IDHEAS-G - Publication
* IDHEAS-ECA - Refinement/Rollout
  - Dependency
  - Integrate with SAPHIRE/SPAR Models
  - Publication of revision
  - Validation vs standards
* IDHEAS-DATA
  - Completion/Publication
  - Revision 11
 
Other HRA Work
* Minimum joint human error probabilities
* Data!
* Wish List
  - Errors of commission
  - Data for Org Factors
  - Security (Physical and Cyber) 12
 
Path Forward
* Complete/Practical HRA Method
* Improvement to the current state of practice at the NRC
* Human-centered, scientific and data-based
* Program for periodic updates based on user feedback and data
* Can be applied to all NRC applications
* Closure of SRM-M061020 13
