文摘
- •
Both steady final bounding state (FIBS) and transient thermal load are analyzed.
- •
A geometry equivalence is conducted from the hemi-elliptical lower head to hemi-spherical one.
- •
A simplified SCDAP/RELAP5 model and detailed COUPLE model are established.
- •
The enough thermal margins could be obtained for ACP100 IVR strategy.
