← ScienceWhich process increases when coolant flow becomes turbulent inside a nuclear reactor?
A)Fission reaction rate decreases
B)Increased heat transfer efficiency
C)Neutron moderation effectiveness rises
D)Wall friction and pressure losses✓
💡 Explanation
Turbulent flow increases wall friction and therefore pressure losses in the cooling system because momentum transfer and viscous forces increase, leading to larger energy dissipation rather than increased heat transfer, under these conditions.
