This thesis explores the role of nuclear power plants as load followers in a hybrid renewable energy system using thermal energy storage. In this case, the author describes a prismatic-core advanced high temperature reactor operating at constant power with molten salt storage supplying power to a secondary energy conversion system. The discussion includes a description of the model and its safety features.
This journal article details the integration concept of solar photovoltaics into a small nuclear power plant. The concept also details the role of thermal energy storage in the hybrid plant.
This work presented in this journal articles uses the Regional Energy Deployment System (ReEDS) model to analyze the impacts of four nuclear retirement scenarios of the U.S. electricity sector, from nuclear plant lifetimes of 50 to 80 years. According to the analysis, longer nuclear lifetimes resulted in lower cumulative and annual carbon emissions, lower transmission builds, and higher energy curtailment and water usage.
This journal article describes a virtual power plant arrangement that combines intermittent offshore wind farm production with firming capacity generated by small to medium-sized reactors. The authors found that the combined system offered several advantages including improved economic performance, flexibility, and reliability.
This journal article presents two hybrid energy system (HES) models. One, termed traditional, produces electricity only and consists of a primary heat generator, a steam turbine generator, a wind farm and a battery storage. The other, termed advanced, includes the components present in the traditional model but also a chemical plant complex to repurpose excess energy for non-electricity services, such as for producing chemical goods.
This journal article describes the benefits of nuclear renewable hybrid energy systems. The authors describe the increased flexibility and emissions reductions that such systems enable as well as the ancillary services they can provide.
This paper considers a generic thermal energy storage (TES) system as a retrofit to an existing nuclear power plant in the United States (Texas). The authors use a validated PLEXOS model of the Electric Reliability Council of Texas electric grid to simulate electricity market clearing in 2030. They use three scenarios of natural gas price forecasts with a coupled capacity expansion model to simulate the deployment of competing technologies.
