Two identical fission chamber neutron detectors, operating in the proportional region, are being used to monitor core neutron flux during a reactor startup.
Detector A has developed a small leak that caused its argon fill gas pressure to decrease to approximately 25 percent of the gas pressure in detector B.
When the reactor reaches criticality, the neutron flux indication produced by detector B will be __________ than the neutron flux indication produced by detector A, primarily because the higher gas pressure in detector B results in __________.
A. greater; more neutron-induced fissions in detector B
B. smaller; fewer neutron-induced fissions in detector B
C. greater; more ionizations in the detector B fill gas
D. smaller; fewer ionizations in the detector B fill gas
