Complete the sentences describing nuclear fission. Choose words from the list below:
During induced nuclear fission, a heavy plutonium-239 __________ absorbs a slow-moving __________ and undergoes division into lighter daughter nuclei. This process is highly exothermic, emitting energy in the form of kinetic energy of the fragments and high-energy electromagnetic radiation as __________.
An interconnected regional power grid requires a minimum reliable electrical power of 58,000 MW58,000\text{ MW}58,000 MW at any given time. To meet this demand, energy planners propose installing a fleet of small modular reactors (SMRs) which each have a maximum electrical power output of 320 MW320\text{ MW}320 MW.
Calculate the minimum number of these SMRs that must be commissioned to fully supply the grid's requirement.
