ABSTRACT
The purpose of Human Factors Verification and Validation (HF V&V) Scenarios is to identify operational
conditions and scenarios to be used for HSI task support verification, design verification and integrated
system validation. HF V&V Scenarios provide detailed scenarios suitable for use on a full-scope simulator
HF V&V Scenarios in this Technical Report contain sampling of operational conditions, summary of
APR1400 probabilistic safety assessment, and HF V&V scenarios.

1.0 OVERVIEW
1.1 Purpose
The purpose of Human Factors Verification and Validation (HF V&V) Scenarios is to identify operational
conditions and scenarios to be used for HSI Task Support Verification, Design Verification and Integrated
System Validation (ISV). V&V Scenarios provide detailed scenarios suitable for use on a full-scope
simulator.
1.2 Scope
The following information is defined to reasonably assure that important dimensions of performance are
addressed, and to allow the scenarios to be accurately and consistently presented for repeated trials:
• a description of the scenario and any pertinent prior history necessary for personnel to
understand the state of the plant at the start-up of the scenario
• specific initial conditions (a precise definition of the plant’s functions, processes, systems,
component conditions, and performance parameters, e.g., similar to that at shift turnover)
• events (e.g., failures) that will occur during the scenario and their initiating conditions, e.g., based
on time, or a value of a specific parameter
• precise definition of workplace factors, (e.g., environmental conditions, such as low levels of
illumination)
• needs for task support (e.g., procedures and technical specifications)
• staffing level
• details of communication content between control room personnel and remote personnel (e.g.,
load dispatcher via telephone)
• scripted responses for test personnel who will act as plant personnel in the test scenarios
