Practice Questions
Question 1
Which of the following phenomena is primarily responsible for the rapid increase in fuel temperature during the initial phase of a large-break loss-of-coolant accident (LOCA) before Emergency Core Cooling Systems (ECCS) activation?
Question 2
In the context of a severe accident, what is the primary consequence of a sustained zirconium-water reaction within the reactor core?
Question 3
Considering a scenario where the Emergency Core Cooling System (ECCS) injects coolant at a rate of $\text{1500 kg/s}$ into a reactor core. If the coolant enters at $\text{300 K}$ and exits at $\text{350 K}$, and the specific heat capacity of water is approximately $\text{4.18 kJ/(kg} \cdot \text{K)}$, what is the rate of heat removal by the ECCS?
Question 4
Which of the following best describes the 'single-failure criterion' as applied to Emergency Core Cooling Systems (ECCS) in nuclear reactor design?
Question 5
What is the primary objective of 'source term reduction' strategies in nuclear safety analysis?
