← ScienceWhich consequence results when rapid coolant vaporization occurs in a nuclear reactor?
A)Reduced neutron moderation efficiency✓
B)Increased core-material ductility
C)Improved steam turbine generation
D)Enhanced heat exchanger performance
💡 Explanation
Rapid coolant vaporization introduces significant voids, diminishing neutron moderation due to a decrease in neutron absorbing collisions; voids introduce positive feedback. Therefore, neutron moderation decreases, rather than increase core heat transfer, because of bubbles.
