PRESSURIZED WATER REACTOR FUEL ASSEMBLY SPACER GRID |
摘要 |
A spacer grid for PWR assemblies (#50) is characterized by curved flow channels (#48) between adjacent fuel rods (#20) and straight, essentially flat strips connecting opposite side plates of the spacer. The latter strips prevent bowing-out of the side plates during fuel assembly fabrication and during operation in the reactor. Additionally, the spacer grid allows accurate positioning of the fuel rods on a square lattice (#50) with a precisely defined pitch, and support of the rods in their spacer cells is such that rod bow will be minimized. |
