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

Gathering Expertise On Vibration ImpaKt In Nuclear Power Generation（GO-维京海盗）项目继承了维京海盗计划，该计划于2020年启动，是欧洲供应商、公用事业公司、技术安全组织、大学和研究机构的一项实物合作努力，旨在提高对与核电反应堆相关的流致振动（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，应采取针对FIV的预防措施，以避免结构磨损、损坏甚至偶然或意外的情况，从而避免潜在的放射性释放到环境中。GO-VIKING的总体目标是增加专业知识，提高欧洲核利益相关者的工具和技能，以分析复杂的FIV现象，以保持和提高核电厂的安全性。这将通过以下方式实现：-生成高分辨率的数值和实验数据的FIV在单相和多相流。- 开发和验证高分辨率和中分辨率，以及用于FIV分析的快速运行的实用工具-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综合FIV分析的最佳实践指南-对毕业生、青年专家以及利益攸关方从业人员进行FIV相关现象和建模技术方面的有针对性的培训维京海盗项目将通过提供新的实验结果和改进的FIV评估数值方法，改善当代反应堆的安全性和新概念的设计评估。这将使核运营商能够加强对NSSS关键部件中FIV现象的预测，并使供应商能够改进相关设备的设计，从而提高欧洲核电厂的可靠性、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
