PUTTING GONUKE INTO PRACTICE: CONSIDERATIONS FOR HUMAN FACTORS EVALUATIONS

The Guideline for Operational Nuclear Usability and Knowledge Elicitation (GONUKE) framework was introduced in 2015 to support human factors evaluations needed for control room upgrades at nuclear power plants. NUREG-0711, the Human Factors Engineering Program Review Model, is used by the U.S. Nuclear Regulatory Commission to review human factors activities associated with human-system interfaces at nuclear power plants, and GONUKE is anchored to the phases of development and design in NUREG-0711. This paper addresses five considerations to help users of GONUKE better apply the framework to evaluations for NUREG-0711 and beyond. These five considerations are: (1) GONUKE only specifies evaluation, not design; (2) GONUKE is a framework, not a method or process; (3) GONUKE goes beyond NUREG-0711 requirements; (4) GONUKE application should follow a graded approach; (5) different evaluations are required for formative vs. summative phases.
