After shutdown, which mechanism causes continued heat generation within a nuclear reactor core?

💡 Explanation

Radioactive decay generates post-shutdown heat because unstable fission daughter products undergo beta and gamma decay, releasing energy as radiation. Therefore, radioactive decay sustains heat output, rather than neutron activation which declines rapidly after shutdown.
