Which statement best describes a System?

• A. A collection of components assembled to perform a function.
• B. An element or collection of elements to provide support or enclosure.
• C. An individual piece of equipment.
• D. The confinement enclosure around the reactor.

Answer: (A)

A system is a group of components that work together to perform a specific function. In a reactor plant, multiple parts—pumps, pipes, valves, sensors—are connected so they can accomplish a purpose, such as moving heat or maintaining safe conditions. This integrated operation is what defines a system, not a single piece of equipment or a structural enclosure. The other descriptions describe either one piece, a support structure, or a containment boundary, none of which by themselves carry out an operational function. For example, the cooling system shows how several parts interact to transfer heat away from the reactor.
