Question

1. losing control of the fission reaction in a reactor core may result in ____.\

\
\bigcirc decreased daughter nuclei\
\bigcirc alpha particles\
\bigcirc a power surge\
\bigcirc a meltdown

Explanation:

When fission reaction control is lost in a reactor core, uncontrolled fission generates extreme heat that can melt the reactor core components, causing a meltdown. Decreased daughter nuclei, alpha particles, and power surges do not directly result from lost fission control in this context.

Answer:

a. a meltdown
