Which consequence results when enriched uranium fuel containing excessive uranium-234 isotopes is used in a pressurized water reactor?

💡 Explanation

Increased U-234 content raises neutron absorption because it is a neutron absorber; the mechanism of neutron capture reduces the concentration of neutrons available for fission; therefore, neutron absorption cross-section increases, rather than other thermal effects that depend on fission.
