Question 10: A nuclear power plant has been operating at rated power for six months when a reactor trip occurs. Which one of the following describes the source(s) of core heat generation 30 minutes after the reactor trip? A. Fission product decay is the only significant source of core heat generation. B. Delayed neutron-induced fission is the only significant source of core heat generation. C. Fission product decay and delayed neutron-induced fission are both significant sources and produce approximately equal rates of core heat generation D. Fission product decay and delayed neutron-induced fission are both insignificant sources and generate core heat at rates that are less than the rate of ambient heat loss from the core
