Nuclear plants in the United States are governed by federal regulations requiring that the electrical power system provide sufficient capacity and capability to the nuclear plant. As part of this analysis, traditional approaches to manually perform single motor start calculations can be tedious and time-consuming. Also, the manual evaluation of the data can easily introduce errors. This presentation takes a closer look at degraded voltage relays (DVRS) and an approach to simulation used by the TVA that is holistic, using ETAP to easily combine the study cases, the revisions, and the configurations into repeatable studies. The demonstration includes the use of an efficient solution using Python code with ETAP to run the studies and evaluate the resultant data.

At a given nuclear power plant, nuclear safety is directly dependent on a reliable source of electric power supplied via the plant’s auxiliary power system.  The auxiliary power system typically consists of an MV and LV AC and a DC distribution system, powering thousands of individual loads and circuits, i.e., pumps, fans, valves, sensors, and controls specifically designed to protect the integrity of the nuclear reactor and containment structures.  This presentation will explore past practices and recent developments in the online monitoring of such systems using a digital twin. The presentation includes the reasons for utilizing online monitoring, the advantages of using a digital twin versus simple data collection, and the multi-faceted benefits realized from such a system (i.e., business, safety, reliability).
