Proceedings of the 32nd International Conference on Nuclear Engineering—Volume 4; ICONE 2025, 22-26 June, Weihai, China

This is the fourth volume of the proceeding papers from the 32nd International Conference on Nuclear Engineering (ICONE 32). This volume covers topics of Track 2, including nuclear fuel and materials, transportation and fuel cycle, and reactor physics.The ICONE, with a history of 35 years, was jointly initiated in 1991 by the American Society of Mechanical Engineers (ASME) and the Japan Society of Mechanical Engineers (JSME). In 2005, the Chinese Nuclear Society (CNS) became one of the conference organizers. Since then, the conference has been co-hosted by CNS, ASME, and JSME, with each society taking turns to organize the event annually. It stands as the preeminent global forum for nuclear professionals who seek to remain at the forefront of technological advancements and industry developments. The ICONE 32, hosted by CNS, took place from June 22 to 26, 2025, in Weihai, China.The proceedings of ICONE 32 summarize the latest advancements in all aspects of nuclear engineering and constitute an invaluable resource for researchers, engineers, policy makers, and graduate students.
