The Knowledge and Abilities Catalog for Nuclear Power Plant Operators: Boiling Water Reactors (BWRs) (NUREG-1123, Revision 2, Supplement 1) provides the basis for the development of content-valid licensing examinations for reactor operators (ROs) and senior reactor operators (SROs). The examinations developed using the BWR Catalog along with the Operator Licensing Examination Standards for Power Reactors (NUREG-1021, Rev. 9, Supplement 1) will sample the topics listed under Title 10, Code of Federal Regulations, Part 55 (10 CFR 55).

The BWR Catalog contains approximately 7,000 knowledge and ability (K/A) statements for ROs and SROs at BWRs. The catalog is organized into six major sections: Organization of the Catalog, Generic Knowledge and Ability Statements, Plant Systems grouped by Safety Functions, Emergency and Abnormal Plant Evolutions, Components and Theory.

Revision 1 to the BWR Catalog modified the form and content of the original catalog. The K/As were linked to their applicable 10 CFR 55 item numbers. SRO level K/As were identified by 10 CFR 55.43 item numbers. The plant-wide generic and system generic K/As were combined in one section with approximately one hundred new K/As. Component Cooling Water and Instrument Air Systems were added to the Systems Section. Finally, High Containment Hydrogen Concentration and Plant Fire On Site evolutions were added to the Emergency and Abnormal Plant Evolutions section.

Revision 2 incorporated corrections to the Rev. 1 catalog that were identified during a pilot testing program associated with revision of 10 CFR 55 and implementation of NUREG-1021, Interim Rev. 8, "Operator Licensing Examination Standards for Power Reactors." Corrections to the catalog included:

  1. addition of 7 K/As that had been omitted in Rev. 1.

  2. correction of typographical errors.

  3. addition of importance value modifiers that had been omitted in Rev. 1.

Revision 2, Supplement 1, includes the following changes:

  1. total replacement of Section 2, "Generic Knowledges and Abilities"

  2. inclusion of one additional Abnormal Plant Evolution (APE), 700000, "Generator Voltage and Electric Grid Disturbances," in Section 4.2 "Generic Abnormal Plant Evolutions"

Corrections and additions are identified by "redline" marking in the margins.
