2. Which of these combinations would be best for submarine propulsion? Explain your choice.
3. State the single most important power cycle parameter affecting the cycle thermal efficiency.
4. Compare the primary side pressures of a PWR, a BWR and a MSR. Describe the reason for
primary side pressure of the PWR being about twice the BWR and the advantage of MSR
primary side pressure being close to atmospheric.
5. Comparing the core of a BWR with that of a PWR, explain the reason a BWR is considered a
closed and a PWR an open core design.
6. Explain the reason that alloys of zirconium are used for fuel cladding.
7. Compare the number of coolant loops and fluids used in a BWR with those of a LMFR -
describe the reason for the differences, if any.
8. What is the key difference in the VVER design from other LWR designs?
9. How do you classify a LFR with respect to neutron spectrum and thermal efficiency as
compared with the SFR?
10. Describe the key difference with respect to core coolant circulation between NuScale and a
typical LWR.
