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.
