“…The use of TRU fuel has also shown promise in enhancing proliferation resistance. The plutoniumcontent reduction, high radiation-dose rate, and heat-generation rate make it difficult to handle these materials at the extraction, transportation, and weaponization stages [34]. This indicates the possibility of cost-effective management of spent-fuel safeguards.…”

This report presents a detailed model for small reactors (SRs) in microgrids, identifying cost and operational data sets for various SR technologies suitable for different microgrid applications. It articulates a path forward for technoeconomic studies of SR in microgrids and the selection of SR technology suitable for different applications and deployment scenarios. This report demonstrates the capabilities of the net-zero microgrid (NZM) Xendee platform for modeling an SR module with electricity, heat extraction and thermal storage in microgrids configurations. The model effectively captures the most important technical and economic considerations for SR technology specific analysis: cost and operational characteristics of SR technology and financial costs and incentives. The model can analyze multiple scenarios to establish metrics for cost-competitive and zero-carbon microgrids connected to the grid or completely isolated. The model is fully integrated within the Xendee platform for modeling and analysis of clean energy microgrids with storage and generation from renewable energy sources. The model captures the capabilities, constraints, and nuances of SR by incorporating parameters related to plant economics, design efficiency and performance, plant operation and component and fuel lifespan, as shown in Figure ES 1 below.

“…18 Furthermore, HTGRs may be a better choice than the other potential reactors for using thorium-based fuels because the use of TRISO particles retains the fission product and resists irradiation very well, thus allowing for a very high fuel burnup. 19,20 Unlike block-type reactors, one of the major challenges in incorporating thorium in pebble-bed reactors (PBR Figure 1) is the difficulty in implementing the S&B concept, because the pebbles are randomly packed in the cylindrical cavity of the reactor core. As a result, the most practical option is to add the driver fuel with thorium into a TRISO particle known as mixed oxide (MOX) fuel.…”
