Question

4. A nuclear engineer is designing a nuclear reactor for a new power plant. The reactor core will have an operating temperature of 773 K. The engineer must choose an appropriate coolant to transfer heat from the reactor core through one or more cooling loops to the steam generator and turbines/generator that produce electricity. Running the coolant under pressure is more expensive than running it at normal atmospheric pressure (1 atm). The choices for the reactor coolant are listed in the table below, with their properties. Choose which substance would be best to recommend to the engineer. Explain your choice in terms of its properties. Explain how the chemical bonds in the substance account for its properties

Answer 1

Sodium Chloride because its still a liquid at the 773 temperature mark<span />
