Abstract

The Knowledge and Abilities Catalog for Nuclear Power Plant Operators: Boiling Water Reactors (BWRs) (NUREG-1123, Revision 3) 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) will 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 1 to the BWR Catalog modified the form and content of the original catalog. The knowledge and abilities (K/As) were linked to their applicable 10 CFR Part 55 item numbers. SRO-level K/As were identified by 10 CFR 55.43, "Written Examination: Senior Operators," item numbers. The plant-wide generic and system generic K/As were combined in one section. 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 Revision 1 catalog that were identified during a pilot testing program associated with revision of 10 CFR Part 55 and implementation of NUREG-1021, Interim Revision. 8, "Operator Licensing Examination Standards for Power Reactors." Corrections to the catalog included:

  1. Addition of seven K/As that had been omitted in Revision 1.
  2. Correction of typographical errors.
  3. Addition of importance value modifiers that had been omitted in Revision 1.

Revision 2, Supplement 1, included the following changes:

  1. Total replacement of Section 2, "Generic Knowledge 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."

Revision 3 includes the following changes:

  1. Clarification of numerous K/A statements and elimination of duplicate K/As.
  2. The addition of the circulating water and service water systems.
  3. All importance ratings (IRs) were re-rated, and except for A2 and generic K/As (which can be the basis for both RO and SRO-only questions), all RO and SRO IRs were replaced with a single IR.
