Proceedings Papers

Proc. ASME. ICONE29, Volume 2: Nuclear Fuel and Material, Reactor Physics and Transport Theory, and Fuel Cycle Technology, V002T02A029, August 8–12, 2022
Publisher: American Society of Mechanical Engineers
Paper No: ICONE29-91377
... into fine fragments (pulvers) in loss-of-coolant accidents. Due to the cladding ballooning under temperature transients, the fragmented fuel can axially relocate into the ballooned region, which may lead to a local increase in cladding temperature and oxidation level, raising the licensing concerns related...

Proc. ASME. ICONE28, Volume 3: Computational Fluid Dynamics (CFD); Verification and Validation; Advanced Methods of Manufacturing (AMM) for Nuclear Reactors and Components; Decontamination, Decommissioning, and Radioactive Waste Management; Beyond Design Basis and Nuclear Safety; Risk Informed Management and Regulation, V003T11A004, August 4–6, 2021
Publisher: American Society of Mechanical Engineers
Paper No: ICONE28-61090
... Abstract The loss of coolant accident (LOCA) is one of the typical design basis accidents for nuclear power plant. Radionuclides leak to the environment and cause harm to the public in LOCA. Accurate evaluation of radioactivity and radiation dose in accident is crucial. The radioactivity...

Publisher: American Society of Mechanical Engineers
Paper No: ICONE2020-16291
... Abstract In a light-water reactor, during normal operating condition, the UO2 nuclear fuel pellets undergo fragmentation primarily due to presence of thermal stresses, fission gas development and pellet-clad mechanical interaction. Under Loss of Coolant Accident (LOCA) conditions, a portion...

Publisher: American Society of Mechanical Engineers
Paper No: ICONE20-POWER2012-54410
... Background of experimental and methodical work is the loss of coolant accident (LOCA) with release of fibrous pipe insulation material. Latest investigations were focused on material deposition and distribution (cross mixing) in the reactor core. Therefore, a 2×2 PWR fuel assembly (FA) cluster...
