Availability Notice


This catalog lists important reactor operator and senior reactor operator knowledge and abilities. Examiners and licensees use the BWR 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 BWR 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 includes the following changes: (1) the clarification of numerous K/A statements and elimination of duplicate K/As, (2) the addition of the circulating water and service water systems, (3) a re-rating of importance ratings for plant systems and emergency and abnormal plant evolutions, and (4) the reduction to a single importance rating for K/As that only relate to one license level.
