“…SRs were assumed to be sufficiently safe to be hosted in an urban area without exclusion boundaries. The installation cost from the previous report 1 was used for SR's purchase cost in the proxy model. e Table 2 summarizes the optimization results for different scenarios for comparison.…”

“…Efforts have been made to represent the cost characteristics of SRs with specific designs modifying the traditional top-down and bottom-up cost estimation techniques used for older NPPs. 10,14 This report utilizes the generic set of parameters identified in the predecessor report 1 to characterize SRs for technoeconomic studies.…”

“…The parameters that are applicable only to SRs are yet to be added. Figure 1 shows the technoeconomic datapoints explored in the earlier report 1 The purchase cost is an area where SRs differ significantly from gas generators. A significant portion of SR's investment cost goes for the plant installation including land rights and site utilities, building and structures, engineering and design, and construction services.…”

“…A significant portion of SR's investment cost goes for the plant installation including land rights and site utilities, building and structures, engineering and design, and construction services. 1 The installation cost calculated for SR in the earlier report 1 is used as the purchase cost of the plant. The economies of scale in the sizing of SR are driven by cost reduction due to factory-produced units and/or co-location of multiple modules at the same site.…”

“…Alternatively, the uranium fuel supply and cost can be manually calculated and translated into the biogas or natural-gas fuel cost for the proxy representation. For the proxy model, the variable O&M cost calculated in the earlier report 1 will be used to represent both fuel and non-fuel costs. Since the gas-generator model needs the specification for the choice of fuel, biogas was selected with a supply price of 0 $/kg because the fuel cost is already considered in the O&M cost.…”

This report presents the results of technoeconomic analysis that advances understanding of the potential of small modular reactors and microreactors, collectively referred to as small reactors (SRs) in this report, in microgrids. This analysis was conducted using a proxy model for SR in microgrids based on the datapoints that were identified and explored in a predecessor report "Small Reactors in Microgrids: Technical Studies Guidance." 1 These datapoints-specific to SRs-are representative of what is understood as of today about the expected characteristics of SRs (costs and operational). They are the starting point for the technoeconomic analysis in this report.This report recognizes that the development of technoeconomic analysis for SRs in microgrids must consider that:• Microgrids built with SRs have different configurations depending on their boundaries, the loads and resources within those boundaries, energy storage, and the connection and interaction with the distribution network. Primary technical design principles include power and energy adequacy, system economics, system reliability, and operational resilience.• Technical studies required to evaluate the feasibility of SR in microgrids include siting, generation optimization, operational framework and feasibility, economic optimization, and risk analysis. Technoeconomic models specific to SRs are necessary to conduct these feasibility studies.
