Which outcome occurs when a breeder reactor's control rods fail?

A)Uncontrolled chain nuclear reaction occurs
B)Neutron moderation decreases significantly
C)Fuel enrichment becomes exceedingly difficult
D)Isotope production rate is diminished

💡 Explanation

An uncontrolled chain reaction starts because the control rods normally absorb neutrons to regulate fission. Without neutron absorption because they fail, the rate of fission increases exponentially, therefore leading to a dangerous surge in core temperature rather than fuel depletion.
