Which consequence results when a nuclear reactor's cooling system fails, and fuel rods reach high temperatures accelerating uncontrolled fission?

💡 Explanation

Increased noble gas production occurs because the fuel cladding ruptures due to excessive heat, allowing noble gases, a byproduct of nuclear fission and radioactive decay, to leak out propelled by thermal expansion rather than by diffusion. Therefore, more fission fragments are released rather than fewer, resulting in more gas.
