Gathering expertise On Vibration ImpaKt In Nuclear power Generation (GO-VIKING)

“收集核能发电中振动影响的专业知识”（GO-VIKING）项目接替了始于2020年的VIKING计划，该计划是欧洲供应商、公用事业公司、技术安全组织、大学和研究组织的一项实物合作，旨在提高对与核电反应堆相关的流激振动（FIV）现象的理解和预测。在核蒸汽供应系统（NSSS）的部件设计和运行过程中，应采取预防FIV的措施，以避免结构磨损、损坏，甚至可能向环境释放放射性物质的偶然或意外情况。GO-VIKING的总体目标是增加欧洲核利益相关者的专业知识，改进工具和技能，以分析复杂的FIV现象，以维持和加强核电站的安全。这将通过生成高分辨率的单相和多相流FIV数值和实验数据来实现。-开发和验证高、中分辨率；以及快速运行的FIV分析实用工具-在FIV结果中实施有效的不确定性传播方法-根据利益相关者的需求合成FIV分析的最佳实践指南-有针对性地培训毕业生和年轻专家以及FIV相关现象和建模技术的利益相关者从业人员GO-VIKING项目将提高当代反应堆的安全性和新反应堆的设计评估通过提供新的实验结果和改进的数值方法来评估FIV的概念。这将使核运营商能够加强对关键NSSS部件中FIV现象的预测，并使供应商能够改进相关设备的设计，从而提高欧洲核电站的可靠性、可用性和安全性

The Gathering expertise On Vibration ImpaKt In Nuclear power Generation (GO-VIKING) project takes over from the VIKING initiative that started in 2020 as an in-kind collaborative effort of European vendors, utilities, technical safety organizations, universities, and research organizations to improve the understanding and the prediction of flow-induced vibration (FIV) phenomena, relevant to nuclear power reactors. Preventive measures against FIV should be taken in the component design and during the operation of the nuclear steam supply system (NSSS) to avoid structural wear, damage or even incidental or accidental scenarios with potential radioactivity release to the environment. The overall objective of GO-VIKING is to increase the expertise and improve the tools and skills of the European nuclear stakeholders for the analysis of complex FIV phenomena in order to maintain and enhance nuclear plant safety. This will be accomplished by: - Generation of high-resolution numerical and experimental data of FIV in single and multiphase flows. - Development and validation of high- and medium-resolution, as well as fast-running practical tools for the FIV analysis - Implementation of efficient methods for uncertainty propagation in the FIV results - Synthesis of best practice guidelines for FIV analysis in accordance with the needs of the stakeholders - Targeted training of graduates and young experts as well as practitioners from stakeholders in FIV related phenomena and modelling techniques The GO-VIKING project will improve the safety of contemporary reactors and the design evaluation of new concepts by making available new experimental results and improved numerical approaches for the evaluation of FIV. These will allow the nuclear operators to enhance the prediction of FIV phenomena in key NSSS components, and the vendors to improve the design of the relevant equipment, thus leading to increased reliability, availability, and safety of the European NPPs
