Which mechanism causes sustained heat generation in a CANDU reactor core?

💡 Explanation

Self-sustaining nuclear fission provides continuous energy because neutron absorption by uranium-235 causes nuclear instability and splitting, therefore releasing kinetic energy and more neutrons to propagate the chain reaction, rather than moderation or bremsstrahlung slowing the chain.
