The Class 1E definition is found in IEEE 308. It is associated with electrical power systems found in nuclear power plants.
IEEE 323 is the standard used to qualify electrical equipment for safety-related use in nuclear power plants. Here, we explore that standard and its requirements. Continue reading
The NRC requires nuclear plants to have both onsite and offsite power systems available to supply safety-related equipment. It also requires that this equipment be periodically inspected and tested so that their condition can be assessed. These requirements are established in General Design Criteria 17 and 18.
