Human Factors Engineering at the U.S.
Nuclear Regulatory Commission Brian Green, Ph.D.
November 26, 2018
NRC Mission The NRC's mission is to regulate the nation's civilian use of byproduct, source, and special nuclear materials to ensure adequate protection of public health and safety, to promote the common defense and security, and to protect the environment.
The NRC's regulatory mission covers three main areas: Reactors, Materials, & Waste
Key Activities Licensing
- Ensure the plant and organization are designed for safe operation
- Use Deterministic/Risk-Informed Approaches Operations & Construction Oversight: Inspections
- Ensure plant is constructed as licensed: ITAAC
- Ensure plant is operated as licensed: tech specs, license conditions Enforcement
- Penalties for operating outside of the terms of the license https://www.nrc.gov/about-nrc/regulatory.html#providing
Nuclear Reactor Overview
- Pressurized Water Reactors (PWR)
- Boiling Water Reactors (BWR)
Operating Reactor Simulator
New Reactor - Simulator
Human and Organizational Factors at NRC
- Operator Licensing
- Operators are knowledgeable, capable, and qualified to safely operating plant
- Safety Culture
- Organization supports safe operation
- Human Reliability Analysis
- Qualitative and quantitative assessments to determine probability of errors
- Human Factors Engineering
- MCR design supports safe operation
- Credited operator tasks feasible/reliable
Human Factors 10CFR50.34(f)(2)(iii) Provide, for Commission review, a control room design that reflects state-of-the-art human factor principles prior to committing to fabrication or revision of fabricated control room panels and layouts.

HFE Reviews HFE Program (NUREG-0711)
HSI Design Criteria (NUREG-0700)
Operator Actions (NUREG-1764)
Review HFE program used for designing a new MCR (or modifying an existing one).
Review an HSI design to verify that good HFE practices are utilized Review proposed significant operator actions.
- 1. Planning & Analysis: OER, FRA/FA, TA, TIHA Acceptance Criteria are based on good human factors design principles Usually focuses on actions outside the MCR
- 2. Design: HSI Design, Procedure Development, Training Program Development Information displays, user-interface interaction and management, controls, alarm systems, safety function and parameter monitoring system, group-view display, soft control system, CBP, Communications, workstation/workspace design, maintainability of digital systems Can operator successfully perform task within time available?
- 3. Verification and Validation Risk-Informed Scaled HFE Program (like NUREG-0711)
- 4. Implementation: DI, HPM Feasibility/Reliability of specific tasks
