Learning Objectives

ENME 431 presents the major fluid systems used in nuclear reactor power plants, including the bases for the designs of these systems. The emphasis is on auxiliary and safety systems; however, primary coolant systems are also discussed. Systems used in existing nuclear power plants are presented, as well as proposed systems for advanced nuclear power plant concepts. Major components used in nuclear reactor fluid systems (pumps, valves and heat exchangers) are discussed. In addition, nuclear reactor safety, including regulatory requirements and safety analysis, are discussed. The major objective of ENME 431 is to have the student understand the fluid systems used in nuclear power plants, including the design bases and safety requirements. A student who successfully completes ENME 431 is able to demonstrate the ability to:
  • Understand the major fluid systems used in nuclear power plants.
  • Understand the design bases and safety requirements for the major fluid systems used in nuclear power plants.
  • Understand the design bases for major components used in nuclear power plant fluid systems including pumps, valves and heat exchangers.
  • Understand the regulatory and safety requirements for the major fluid system used in nuclear power plants.
