Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

"Fuel rod" seems to commonly be used for "fuel rod assembly". Am I correct that each assembly consists of the zirconium tube and the cylindrical pellets?

Plus the presurized helium inside and what ever attachments there are on the tube to allow it to fit into one of the four assemblies. Or are you saying that the core of a reactor consists of more than four assemblies, each containing ~25 tubes filled with pellets. I really don't know how schematic the diagrams are.

The reactor core contains hundreds of assemblies, each of them containing about a hundred tubes, arranged in four bundles. Assemblies can be individually moved. About 1/5 of the fuel is replaced each year.

No, an assembly consists of 100-odd zirconium rods or canisters containing the fuel pellets.
The assembly is designed to be grabbed by a crane.
