Which outcome arises when reactor coolant flow is disrupted?

💡 Explanation

A loss of coolant triggers Doppler broadening in the fuel, decreasing neutron absorption, because nuclear fission accelerates and heat increases dramatically; therefore, a runaway reaction scenario occurs, rather than controlled shutdown or altered helium production.
