N2 - This paper describes the use of Rancor, a reduced order models (ROMs) in integrated systems modeling for nuclear power plant simulators. We introduce Rancor, a ROM-based nuclear power plant simulator with a thermal power dispatch system that was part of a NREL and Idaho National Laboratory Superlab 2.0 demonstration using ESnet OSCARS service for high-speed data transfer. The model communicated in real-time with an RTDS server, which exchanged data with a grid simulator at NREL modeling solar power and battery storage. We highlight the benefits of Rancor over alternative full-scope simulators, such as its simplicity, predictability, and flexibility in development. Additionally, we discuss the challenges of grid stability with the proliferation of renewable energy sources and discuss the concept of nuclear power flexible plant operations and generation (FPOG) as a solution for improving grid stability and integrating high penetrations of renewable energy sources into power grids. Overall, the paper argues that reduced order models such as Rancor could play a key role in developing the next generation of nuclear power plant technologies and promoting grid stability, with the support of advanced cyber infrastructure such as ESnet ARIES and OSCARS.
