Students explain the fundamentals of chemistry to include atomic structure and 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. 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 reactor water chemistry.
