This course, Reactor Auxiliary Systems, contains four modules: Containment and Ventilation of Reactors, Spent Nuclear Fuel Storage and Handling Procedures, Emergency Power Systems for Reactors, and Residual and Emergency Cooling Systems for Reactors. Each module follows a typical format including the following sections: introduction, module prerequisites, objectives, subject matter, exercises, materials, procedures, data tables, reference materials, and tests.
