ABSTRACT

The Knowledge and Abilities Catalog for Nuclear Power Plant Operators: Westinghouse 

AP1000 Pressurized-Water Reactors (NUREG-2103, Revision 0) provides the basis for the 

development of content-valid licensing examinations for reactor operators (ROs) and senior 

reactor operators (SROs). The examinations developed using this Catalog along with the 

Operator Licensing Examination Standards for Power Reactors (NUREG-1021) will sample the 

topics listed under Title 10, Code of Federal Regulations, Part 55 (10 CFR 55).

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 Operating Evolutions, Components, and Theory.

This is a new Knowledge and Abilities catalog developed specifically to address the passive 

nature of the Westinghouse AP1000 design.

1.10.2 K/A Stem Statements for EOPs and AOPs

The information delineated within each emergency plant evolution is organized into 3 different 

types of knowledge and 2 different types of ability. If there are no knowledge or ability 

statements following a stem statement, there is no applicable K/A; these are marked N/A.

The applicable 10 CFR: 55.41 / 43 / and 45 item numbers are included with each stem 

statement. In most cases the K/As associated with the stem statements can be used for both 

the written examination and the operating test. See Table 4 below:

Basic components such as valves and pumps are found in many systems. NUREG-1021 lists 8 

categories of components. The 8 categories of components for which additional knowledge 

statements are necessary are listed below and delineated in Section 5 of this catalog.
NUREG-2103, Rev. 0 1-10

The component knowledge statements are more detailed than those provided in the system 

listing, yet at the same time they are generic to the component types. Each component has a 

unique 6-digit code number identified in NUREG-1021, and 10 CFR 55.41(b) item number. See 

Table 5, below.

1.13 Importance Ratings

Importance, in this context, considers direct and indirect impact of the K/A on safe plant 

operation in a manner ensuring personnel and public health and safety. Importance Ratings of 

the K/As are given next to each knowledge and ability in the catalog. These ratings reflect 

average ratings of respondents. The rating scale is presented in Table 6, below:

Table 6

RO and SRO Importance Ratings

Rating Importance for safe operation

5 Essential

4 Very important

3 Fairly important

2 Of limited importance

1 Insignificant Importance

Therefore, the rating of 2.0 or below represents a statement of limited or insignificant 

importance for the safe operation of a plant. Such statements are generally considered as 

inappropriate content for NRC licensing examinations. (See below for qualifications of 

importance ratings related to variability of the ratings and plant specific data.)

1.14 Rules of Use

To ensure consistency in applying this catalog the following terms are interpreted as:

• “Parameters” include any characteristic of a system/component that is measured.

• “Actuation” includes actuation logic, signals, blocks, bypasses, permissives, interlocks, 

and resets.

1.15 General Guidance

The following strategies and principles are utilized in this catalog:

• The use of set points is minimized. Values included are specific to titles or 

procedures. If a value included in the catalog changes, the statement is still testable 

if it meets the intent of the statement.

• KA statement overlap in multiple sections is minimized. KAs are assigned to the 

most appropriate section.

• All importance ratings are single column format except A2 and Generic K/As and fuel 

handling. Fuel handling is not a RO license activity and will have N/A marked in the 

RO column.
