The Knowledge and Abilities Catalog for Nuclear Power Plant Operators: Pressurized-Water Reactors (PWRs) (NUREG-1122, 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 PWR 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 PWR Catalog contains approximately 5,100 knowledge and ability (K/A) statements for ROs and SROs at PWRs. The catalog is organized into six major sections: Catalog Organization, Generic Knowledge and Ability Statements, Plant Systems, Emergency and Abnormal Plant Evolutions, Components and Theory.

Revision 1 to the PWR 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. Systems were organized into nine safety functions and the emergency and abnormal evolutions were reorganized and expanded.

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 K/As that had been omitted in Rev. 1 (approximately 70).

  2. deletion of duplicate K/As (approximately 15).

  3. correction of importance values of consolidated K/As to reflect highest previously assigned values (approximately 75).

  4. correction of typographical errors.

  5. addition of importance value modifiers that had been omitted in Rev. 1 (approximately 225).

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), 077, "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.
