Availability Notice


This catalog lists important knowledge and abilities for reactor operators and senior reactor operators at pressurized water reactors. Examiners and facility licensees use this catalog along with NUREG-1021, "Operator Licensing Examination Standards for Power Reactors," to develop examinations that sample the topics listed under Title 10 of the Code of Federal Regulations (10 CFR) Part 55, "Operators' Licenses." The catalog is organized into six major sections: Organization of the Catalog, Generic Knowledge and Abilities, Plant Systems, Emergency and Abnormal Plant Evolutions, Components, and Theory.

Revision 3 of the catalog includes the following changes: (1) the clarification of numerous knowledge and ability statements and the elimination of duplicate statements, (2) the addition of the integrated control and control room ventilation systems and the incorporation of the station air system into the instrument air system, (3) the addition of reactor coolant system leak to the abnormal plant evolutions, (4) retention of applicable knowledge and ability statements that were moved to other sections with the deletion of the station air system, reactor coolant pump malfunctions (Loss of Reactor Coolant Flow), Combustion Engineering reactor coolant system overcooling, and Combustion Engineering natural circulation operations, (5) a complete rewrite of the vendor-specific emergency plant and abnormal plant evolutions sections, (6) a rerating of importance ratings for Plant Systems and Emergency and Abnormal Plant Evolutions sections, (7) the reduction to a single importance rating for knowledge and ability statements that only relate to one license level, and (8) the addition of a Basic Energy Concepts section to Thermodynamics Theory.
