Abstract

In advanced pressurized water reactors, the corrugated plate dryer (CPD) is essential for ensuring the safety and efficiency of nuclear power plants by influencing steam quality in the separation system of steam generators. While previous research has focused on cold-condition experiments, this study addresses the complexities of hot operational conditions, which are more representative of real-world scenarios. By investigating the effects of CPD structural parameters on separation performance, the research establishes an experimental platform that reveals a critical plate spacing where the CPD’s critical velocity (CV) peaks. Additionally, the study explores the internal gas flow dynamics, demonstrating that increased recirculation along the plate walls significantly impacts flow velocity. These findings contribute to a deeper understanding of CPD performance under realistic conditions, enhancing the reliability and efficiency of nuclear power generation.

热工况下蒸汽发生器波纹板干燥机的实验研究

在先进压水堆中，波纹板干燥器通过影响蒸汽发生器分离系统中的蒸汽质量，对核电厂的安全与效率起着至关重要的作用。虽然之前的研究主要集中在冷工况实验，但本研究解决了热工况的复杂性，这更能代表现实世界的场景。通过研究CPD结构参数对分离性能的影响，建立了一个实验平台，揭示了CPD临界速度（CV）峰值的临界板间距。此外，该研究还探讨了内部气体流动动力学，表明沿板壁增加的再循环显著影响流动速度。这些发现有助于更深入地了解CPD在现实条件下的性能，提高核电的可靠性和效率。

期刊介绍： Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
