In a commercial Pressurized Water Reactor (PWR), why is a negative Moderator Temperature Coefficient (MTC) required?

It provides inherent self-limiting feedback: an increase in coolant temperature decreases moderation and reduces reactor power It ensures control rod insertion speed increases automatically when coolant temperature rises It prevents fuel cladding oxidation by reducing coolant pressure at elevated temperatures It maximizes thermal efficiency by suppressing subcooled nucleate boiling in fuel channels

Correct Answer:

It provides inherent self-limiting feedback: an increase in coolant temperature decreases moderation and reduces reactor power
