This report provides initial guidance for the technical studies that are needed for the integration of small reactors (SR)—i.e., small modular reactors (SMR) and microreactors—in microgrids. Power-system engineering issues related to the configuration of these microgrids and their interconnection and interaction with the grid are identified. This guidance applies microgrid concepts to the deployment of SRs for a range of use cases (scenarios). Further, it identifies issues and necessary studies related to laboratory testing and validation of various configurations of SR in microgrids.
