ICONE19-43629 LOCAL PANELS AND MAINTAINABILITY HUMAN FACTORS ASSESSMENT FOR AP1000^[○!R] NUCLEAR POWER PLANT

Abstract

A document entitled "AP1000 Local Panels and Maintainability Human Factors Design Guidelines" was produced to aid the designers to specifically include human factors (HF) considerations in the design, operation, and maintenance of local control stations and plant equipment. To ensure that the applicable HF design guidelines are appropriately applied to the design of local panels and maintenance activities, and identify any HF improvement opportunities that can readily be implemented at the design stage, a HF assessment of maintenance activities and local plant operations is underway. This assessment gives priority to local control stations and equipment which have been identified as having a potential impact on safety. This includes risk-significant systems, structures and components (SSCs) identified through the probabilistic risk assessment (PRA), and local operator actions as required by the Emergency Operating Procedures (EOPs). Local actions, maintenance activities and associated operator interfaces are reviewed against the relevant HF guidelines. The results of the assessment include a description of the component, associated local actions and/or required maintenance activities, good design features and/or potential issues, and recommendations for change or improvement. These results are communicated to responsible design engineers who evaluate the impact to plant design and implement design changes, if deemed necessary.
