Students explain the fundamentals of chemistry to include atomic structure, the periodic table, chemical bonding, molecular structure, mixtures, solutions and compounds, and properties and uses of gases. They explain the theory of corrosion chemistry, pH and ion exchangers that are key to power plant water systems. They describe the methods and systems used for water chemistry control, steam generator chemistry, and secondary chemistry control. For reactor water chemistry, they analyze the types, sources, effects and control/removal of impurities. Students describe the factors involved with radiochemistry, radiolysis and recombination and hydrogen gas that are essential to water chemistry. Students study combustion and the constituents that make up fossil fuels. Fuel classification is described, methods of analyzing, and the utilization of the maximum amount of energy stored in the fuels.
