Technology Marketing Summary

A new software tool enables the easy and quick selection of applicable regulatory guidelines as a starting point for human factors engineering (HFE) analyses.  Once selected, each guideline can be viewed on screen.  The software tracks and reports the status of HFE analyses and may be accessed simultaneously by multiple users.

Description

Design Review Guidelines,” issued by the Nuclear Regulatory Commission (NRC).  NUREG 0700 includes over 1,650 distinct guidelines.  NRC provides a software tool, the Design Review Guide, to assist in the NUREG 0700 guideline analysis process.  However, the burden for selecting which of the 1,650 guidelines are applicable to a given process is placed on the user.  Manual selection of appropriate guidelines can be tedious.  It also can lead to inconsistencies among analyses due to different user preferences or interpretations.

In developing the Human Factors Engineering Analysis Tool (HFE-AT), a team of HFE subject matter experts reviewed and categorized all 1,650+ NUREG 0700 guidelines.

The Guidelines were sorted into the following categories:

•  System technical applicability (computer based or non-computer based). •   System functional applicability (safety basis or non-safety basis).

The guidelines also were sorted by the following types:

•  General concept:  highest level or most general description of a topic that is common to two or more guidelines. •  Supporting detail:  guidelines that address specific details associated with general concepts. •  Stand-alone:  any other guideline that is sufficiently important to be considered individually.

The selection of type is dependent on the selection of category.  For example, supporting detail guidelines will only be selected for safety basis analyses.  This system default mode can, however, be overridden by the user who may view and select specific supporting details for non-safety basis analyses.

The user also can enter specific user-defined guidelines in addition to the preloaded guidelines.

As an example of its inherent efficiency, the FHE-AT software consistently selects only 620 of the NUREG 0700 guidelines as a starting point for typical analyses involving computer-based, non-safety basis process control systems.
