With regard to typical Westinghouse Pressurized Water Reactor (PWR) Excore Nuclear Instrumentation, how is the "power range" instrumentation utilized by the Rod Control System power mismatch circuit? Group of answer choices The circuit compares core upper and lower flux to determine the direction and speed of control rod motion. The circuit computes a nuclear versus core thermal power mismatch to determine the direction and speed of control rod motion. The circuit compares core quadrant power to determine the direction and speed of control rod motion. The circuit computes a nuclear versus turbine power mismatch to determine the direction and speed of control rod motion
