A boiling water reactor uses which of the following materials as its primary fuel________________?
Show answer Hide answer
Answer: A. enriched uranium
Explanation
Boiling water reactors require specific fuel compositions to sustain continuous nuclear fission chain reactions. Enriched uranium contains a higher percentage of the fissile isotope uranium-235 than natural ore. This increased concentration is necessary to maintain criticality within commercial nuclear reactor cores. Natural uranium contains less than one percent fissile uranium-235, which is insufficient for light water reactors. Enrichment processes increase uranium-235 proportions through gaseous diffusion or advanced centrifuge technologies. Ceramic uranium dioxide pellets are fabricated from this enriched material and loaded into fuel rods.
Nuclear power plants rely on enriched uranium fuel to generate electricity efficiently on a commercial scale. Fuel management programs monitor enrichment levels to optimize reactor operational cycles and power output. Handling enriched nuclear fuel requires stringent safety protocols to prevent criticality accidents. Plutonium is produced artificially in breeder reactors rather than being the primary fuel for standard plants. Thorium serves as a fertile material requiring conversion into uranium-233 before sustaining fission. Natural uranium lacks sufficient uranium-235 concentration to operate light water boiling reactors efficiently.
