What are prompt and delayed neutrons? Discuss the role of delayed neutrons in reactor safety.
Prompt neutrons are those emitted almost immediately (within about 10⁻¹⁴ seconds) during the fission process of a heavy nucleus like uranium-235 or plutonium-239. They are released directly from the splitting of the nucleus and constitute the majority of neutrons in a fission event, typically around 99% of the total neutrons produced. These neutrons are highly energetic and play a primary role in sustaining the chain reaction in a ____ _____ ________ ________ ___.
