Core configuration shall include what?

Core configuration shall include what?

• A. The number, type, or arrangement of fuel assemblies, graphite moderator elements, experimental locations, and control blades occupying the core region
• B. The reactor vessel material
• C. The coolant type and pressure
• D. The turbine generator model

Answer: (A)

Core configuration is about what is physically inside the reactor core and how it is arranged, because these pieces determine how neutrons behave. It includes the number, type, and arrangement of fuel assemblies, graphite moderator elements, experimental locations, and the control blades occupying the core region. These components govern reactivity and the neutron flux distribution, which are central to safe and predictable reactor operation. The reactor vessel material, the coolant type and pressure, and the turbine generator model pertain to other plant systems and do not define the core’s neutronic layout.
