The NRC Approach to Human Factors:
A Quick Start Guide Brian Green, Ph.D.
U.S. Nuclear Regulatory Commission Senior Technical Advisor for Human Factors t,NPIC HMIT=
N 14th International Topical Meeting on Nuclear Plant Instrumentation, Control &
Human-Machine Interface Technologies
NRC Human Factors Reviews: At a Glance NRC Overview
- NRC Mission
- NRC Values
- Principles of Good Regulation
- Risk-Informed Regulation Human Factors Engineering Reviews Ensure human factors principles are considered and applied to support safe operation
- State-of-the-art human factors principles - 10 CFR 50.34(f)(2)(iii)
- Systems approach to engineering merged with human information processing model (NUREG-0711) 8ANs*
Key Regulatory Processes Part 53 for Advanced Reactors Risk-Informed, performance-based, technology neutral Aspects of both, part 50 and 52 for advanced reactors Considers HFE wherever operators have role in safety New considerations for remote operation &
autonomy Part 50 Construction Permit Operating License Part 52*
Design Certification Combined Operating License Although the regulatory processes are different between Parts 50 and 52, the level of detail needed is similar for HFE in both. Part 52 uses pointers to Part 50 regulations to ensure consistency. Timing of HFE submittals also varies.
- Part 52 introduces the idea of a standardized design. It allows the use of Design Acceptance Criteria (DAC) to delay some parts of the human factors design until after licensing is complete (SECY 92-053). NUREG-0711 describes submittals necessary for the staff to conduct a review of a design using (DAC).
8ANs*
Regulatory Scope Considered for HFE
- Power reactor control rooms designs
- 10 CFR 50.34(f)(2)(iii), 52.79, Other TMI requirements (such as SPDS)
- Human factors in response to TMI NRC gave orders for plants to evaluate MCR - Detailed Control Room Design Review (DCRDR) (NUREG-0737 and NUREG-0700)
Created plant-specific baseline control room design
- changes to the baseline are evaluated against 10 CFR 50.59 criteria.
- Some focused review outside MCR
- Important human actions (IHA) credited in safety analysis and PRA 8ANS.
Key Review Criteria
- NUREG-0800 Chapter 18-Standard Review Plan (SRP)
- Provides a standard approach to conducting technical reviews
- 10 CFR 50.34 indicates that licensees must prepare an application that conforms with the SRP or provide an alternate approach
- incorporates other documents by reference
- NUREG-0711 - Describes an acceptable approach for developing a human factors design and evaluation program Provides additional insights about processes that can be useful for applying other documents below
- NUREG-0700 - Provides human-system interface design guidelines
- NUREG-1764 - Evaluating changes to credited operator actions
- Others: DRO-ISG-2023-02, DRO-ISG-2023-03,
- Research Information Letters (RILS): Research that will be included in future updates to the documents above Join the new Listserv for updates
