Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Calculate the total energy released in a chain reaction that starts with 10 nuclei of U-235, each undergoing fission, assuming each fission releases 200 MeV.

💡 Hint: Remember to multiply the number of reactions by the energy released per reaction.

Challenge 2 Hard

Explain how the design of a nuclear reactor impacts its efficiency and safety, discussing the roles of moderators, control rods, and coolant systems.

💡 Hint: Consider how each component interacts to either enhance or limit reactions.
