BWX Technologies has started manufacturing the reactor core for the Pele microreactor at its Lynchburg, Virginia facility. The Pele microreactor will provide 1.5 megawatts of electricity and is expected to begin production in 2028. Key partners include Rolls-Royce for the power conversion module and Northrop Grumman for the control module. The Pele microreactor is designed to be transportable and will operate using TRISO fuel, a high-assay low-enriched uranium fuel type.
BWX Technologies has initiated the production of the reactor core for the Pele microreactor at its Lynchburg, Virginia facility. The Pele microreactor, designed to generate 1.5 megawatts of electricity, is expected to begin operations in 2028. Key partners include Rolls-Royce for the power conversion module and Northrop Grumman for the control module. The Pele microreactor is engineered for transportability and will utilize TRISO fuel, a high-assay low-enriched uranium fuel type.The Pele microreactor is part of the growing trend towards small modular reactors (SMRs) and nuclear microreactors (NMRs) that aim to meet energy needs in remote and challenging locations. These reactors offer advantages such as light weight, transportability, rapid deployment, and extended refueling periods, making them suitable for areas where traditional power generation methods are less viable [1].
The use of TRISO fuel in the Pele microreactor aligns with the trend of utilizing advanced fuel types in nuclear reactors. Thorium-based fuels, which can be used in combination with fissile materials, have been explored in various reactor designs. Studies have shown that thorium can improve fuel efficiency and reactor safety, but require careful loading and optimization to achieve optimal performance [2].
BWX Technologies' commitment to manufacturing the Pele microreactor's reactor core is a significant milestone in the development of advanced nuclear technologies. The collaboration with Rolls-Royce and Northrop Grumman underscores the industry's focus on innovation and integration of cutting-edge technologies to enhance nuclear energy's role in the global energy mix.
