摘要

这项研究调查了球形管板作为 APR1400 和 AP1000 蒸汽发生器中传统扁平管板的更有效替代品的潜力。通过利用球形结构的固有强度，我们旨在减少材料消耗、制造成本和施工时间。我们采用有限元法模拟来比较扁平管板和球形管板在高温高压条件下的变形行为。分析确定了最佳的球形管板厚度，在保持结构完整性的同时显著减少了厚度：APR1400 和 AP1000 的厚度分别减少了约 20-30% 和 40-50%。此外，球形设计还可以通过最大限度地减少传热管长度的变化来提高热效率，从而使热量分布更加均匀。

A study of spherical tubesheet design for APR1400 and AP1000 steam generators

This research investigates the potential of spherical tube sheets as a more efficient alternative to conventional flat tube sheets in APR1400 and AP1000 steam generators. By leveraging the inherent strength of spherical structures, we aim to reduce material consumption, manufacturing costs, and construction time. Finite Element Method simulations were employed to compare the deformation behavior of flat and spherical tube sheets under high-temperature and high-pressure conditions. The analysis identified optimal spherical tube sheet thicknesses that maintained structural integrity while achieving significant reductions in thickness: approximately 20–30 % for APR1400 and 40–50 % for AP1000. Moreover, the spherical design can enhance thermal efficiency by minimizing variations in heat transfer tube lengths, leading to more uniform heat distribution.
