In a liquid-metal fast breeder reactor (LMFBR), the immense thermal energy released by nuclear fission reactions in the core is absorbed by liquid sodium coolant.
Describe how this thermal energy is transferred from the reactor core to produce high-pressure steam, and explain why the sodium is kept separate from the water.
