How many fuel plates are there per full bundle?

• A. 14 plates
• B. 12 plates
• C. 15 plates
• D. 16 plates

Answer: (A)

The number of fuel plates in a full bundle is a fixed design parameter that matches the fuel assembly’s geometry and cooling paths. In this design, a full bundle uses fourteen plates. That count provides enough fuel mass and surface area for effective heat transfer while leaving adequate coolant channels between plates and within the bundle to fit the core’s dimensions and maintain proper flow. If there were fewer plates, the bundle would have less fuel material and less surface area for heat transfer, which can raise local power density and challenge cooling. If there were more plates, the coolant flow could be restricted and the pressure drop increased, potentially affecting cooling and the fit within the core. The fourteen-plate configuration is chosen to balance these factors and meet the reactor’s core design requirements, making it the standard for a full bundle in this context.
