With regard to the BWR/4, Boiling Water Reactor nuclear instrumentation design, which of the following correctly describes the "Rate Change Circuit"? Group of answer choices The rate change circuit determines the rate of change of gamma energy and displays an output signal as startup rate (factor of "e"). The rate change circuit determines the rate of change of gamma energy and displays an output signal as reactor period (decades per minute). The rate change circuit determines the rate of change of the neutron count rate and displays an output signal as reactor period (factor of "e"). The rate change circuit determines the rate of change of the neutron count rate and displays an output signal as startup rate (decades per minute)
