    Automation awareness has been recently discussed as a major factor to be taken into account in the design of modern NPP control room solutions. In this paper, we present an advanced version of an automation awareness simulator user interface, which we have been developing. The main focus of this paper is in user studies where we investigated the automation awareness of operators using our simulator to master several test scenarios. Altogether 12 Loviisa NPP workers participated to the study. One test session included both normal and fault scenarios related to the periodic testing of an emergency diesel generator system. In addition to the test tasks, one session included also interviews and an automation awareness questionnaire, which we had developed especially for these studies. In this paper, the preliminary results of the user studies are described and initial conclusions reported. For example, the digital presentation of the measurement values, graphical presentation of the values' status and their automation-related limits, and illustrative trend displays were seen to improve automation awareness. The results of the studies confirm the notion that in addition to the operators' experience and training, the quality of user interface is a significant contributor to the development of automation awareness.
