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.

SUMMARY OF SIGNIFICANT CHANGES

The changes to Revision 3 include:

1. Correctly linked each K/A to the areas and evolutions identified in 10 CFR 55.41, “Written 

Examination: Operators”; 10 CFR 55.43, “Written Examination: Senior Operators”; and 10 

CFR 55.45, “Operating Tests.”

2. Provided clear and specific guidance in the K/A statement(s) that identifies the expectation 

for use of a procedure reference, and labeled applicable open-reference question K/As with 

“reference potential.” 

3. Enhanced K/A stem statements to more clearly define the level of detail and content to 

support consistent evaluation (i.e., similar to the new plant K/A catalog statements).

4. Identified K/A statements that apply to specific plant designs as applicable to that design 

within the actual statement.

5. Clearly identified K/A statements that apply to only the Senior Operator position as “SRO 

Only.”

6. Eliminated RO/SRO Importance Ratings (IRs) and replaced with a single IR EXCEPT for 

the A2, G, and fuel handling categories.

7. Deleted K/A statements in the plant systems sections that were redundant with the K/As 

contained in Section 5, “Components.”

8. Reviewed and deleted all “Definition” K/As where appropriate.

9. Standardized common systems between the PWR and BWR catalogs.

10. Re-rated all importance ratings.

11. Removed K/As that are part of general employee training (basic tasks that a general 

nuclear worker is already evaluated on with some periodicity).

12. Added K/A statements for the circulating water and service water systems, which were 

previously overlooked

13. Eliminated the overlap in the A3 and A4 statements and redundancy in the K3 statements 

related to the specific system.

14. Removed the list of tasks at the beginning of systems.

1 ORGANIZATION OF THE CATALOG

1.1 Introduction

The “Knowledge and Abilities Catalog for Nuclear Power Plant Operators: Boiling Water 

Reactors (BWR),” NUREG-1123, Revision 3, provides the basis for development of contentvalid written and operating licensing examinations for reactor operators (ROs) and senior 

reactor operators (SROs). The catalog is designed to ensure equitable and consistent 

examinations.

1.2 Part 55 of Title 10 of the Code of Federal Regulations

The catalog is used in conjunction with NUREG-1021, “Operator Licensing Examination 

Standards for Power Reactors.” NUREG-1021 provides policy and guidance and establishes the 

procedures and practices for examining licensees and applicants for RO and SRO licenses 

under Title 10 of the Code of Federal Regulations (10 CFR) Part 55. All knowledge and abilities 

(K/As) in this catalog are directly linked by item number to 10 CFR Part 55.

1.3 RO Written Examination

The guidance for preparation of the RO written examination is presented in NUREG-1021. The 

specific items for RO written examinations are presented in 10 CFR 55.41(b).

1.4 SRO Written Examination

The guidance for preparation of the SRO written examination is presented in NUREG-1021. In 

addition to the RO items specified in 10 CFR 55.41(b), additional items for SRO written 

examinations are presented in 10 CFR 55.43(b).

1.5 RO and SRO Operating Test Items

The items for operating tests for ROs and SROs are presented in 10 CFR 55.45(a). The 

guidance for the preparation of operating tests is presented in NUREG-1021. The operating test 

should include a representative selection of K/As derived from those items listed in 10 CFR 

55.45(a).

1.6 Senior Operators Limited to Fuel Handling

The specifications for examinations for Senior Operators Limited to Fuel Handling (LSRO) are 

provided in Examination Standards (ES)-701 and -702, NUREG 1021. The LSRO examination 

process includes both a written examination and an operating test. These examinations and 

tests include, but are not limited to, items associated with 10 CFR 55.43(b), Items 5 through 7, 

and 10 CFR 55.45(a), Items 5 and 6.

1.7 Organization of the BWR Catalog

The “Knowledge and Abilities Catalog for Nuclear Power Plant Operators: Boiling Water 

Reactors” is organized into six major sections. K/As are grouped according to the major section 

to which they pertain. This organization is shown schematically below.

1.8 Generic Knowledge and Abilities

Generic knowledge and abilities (K/As) are generally administrative K/As with broad application 

across systems and operations. They are listed in Section 2 of the catalog. The four categories 

of generic K/As are listed below:

2.1 Conduct of Operations K/As

2.2 Equipment Control K/As

2.3 Radiation Control K/As

2.4 Emergency Procedures/Plan K/As

The generic K/As for “Conduct of Operations” are used to evaluate the applicant’s knowledge of 

the daily operation of the facility. The types of information covered under this category may 

include for example, shift turnover, operator responsibilities, and procedure usage.

The generic K/As for “Equipment Control” are used to evaluate the administrative requirements 

associated with the management and control of plant systems and equipment. Examples of the 

types of information evaluated under this topic include maintenance and temporary 

modifications of systems.

The generic K/As for “Radiation Control” are used to evaluate the applicant’s knowledge and 

abilities with respect to radiation hazards and protection (personnel and public). Examples of the 
1-3

types of information that should be evaluated under this topic are knowledge of significant 

radiation hazards or radiation work permits.

The generic K/As for “Emergency Procedures/Plan” are used to evaluate the applicant’s general 

knowledge of emergency operations. The K/As are designed to evaluate knowledge of the 

emergency procedures use. The emergency plan K/As may be used to evaluate the applicant’s 

knowledge of the plan, including, as appropriate, the RO’s or SRO’s responsibility to decide 

whether it should be executed and the duties assigned under the plan.

1.9 Plant Systems

Plant Systems Organization by Safety Function

Nine major safety functions must be maintained to ensure safe BWR nuclear power plant 

operation. The safety functions are:

1. Reactivity Control

2. Reactor Water Inventory Control

3. Reactor Pressure Control

4. Heat Removal from the Reactor Core

5. Containment Integrity

6. Electrical

7. Instrumentation

8. Plant Service Systems

9. Radioactivity Release.

Plant systems have been included in the BWR Catalog based on their relationship and 

importance to safety functions. Table 1 contains a list of these plant systems, arranged by

safety function. It should be noted that some plant systems contribute to more than one safety 

function.

Each plant system has a six-digit code number. The words “Plant Specific” after the system title 

indicate that the knowledge or ability does not apply to all plants.

See Section 3 of the BWR catalog for the delineation of K/As for the plant systems.

Knowledge and Ability Stem Statements for Plant Systems

The information delineated within each plant system is organized into six (6) different types of 

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

following a stem statement there is no applicable K/A.

The applicable item numbers from 10 CFR 55.41, “Written Examination: Operators”; 

10 CFR 55.43, “Written Examination: Senior Operators”; and 10 CFR 55.45, “Operating Tests”

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 2 

below for stem statements and basis.
1-6

Table 2: Knowledge and Ability Stem Statements for Plant Systems

K1. Knowledge of the physical connections or cause-effect relationships between the 

(SYSTEM) and the following systems:

(CFR: 41.2 to 41.9 / 45.7 to 45.8)

Basis – K1 contains the systems that have a connection to (SYSTEM). The “concepts” 

will move from K1 to K5 where the stem statement covers concepts. “Cause and effect 

relationship” will remain so that questions to that effect can be written in K1. The specific 

controls and interlocks are listed in K4. Electrical systems typically were not included in 

K1, they are addressed in K2.

K2. Knowledge of electrical power supplies to the following: (CFR: 41.7)

Basis – K2 lists the power supplies to system components for which knowledge of power 

supplies is testable. The intent is to include the required knowledge for power supplies to 

components that are important to safe plant operation or operationally significant. When 

determining importance or significance, consider plant specific PRA, technical 

specifications, plant specific operating experience, emergency procedures, and 

abnormal procedures.

K3. Knowledge of the effect that a loss or malfunction of the (SYSTEM) will have on the 

following systems or system parameters: (CFR: 41.7 / 45.4)

Basis – K3 lists the systems included in K1 that will be affected by a loss of (SYSTEM).

K4. Knowledge of (SYSTEM) design feature(s) or interlock(s) that provide for the following: 

(CFR: 41.7)

Basis – K4 contains the plant protection/control design features and interlocks.

K5. Knowledge of the operational implications or cause-effect relationships of the following 

concepts as they apply to the (SYSTEM):

(CFR: 41.5 / 45.3)

Basis – The stem for K5 was revised to include cause-effect relationships and concepts. 

Contains theoretical concepts related to the operation of the system.

K6. Knowledge of the effect of the following plant conditions, system malfunctions, or 

component malfunctions on the (SYSTEM): (CFR: 41.7 / 45.7)

Basis – The stem for K6 was modified to address plant conditions, system malfunctions, 

and component malfunctions on (SYSTEM). K6 lists the systems included in K1 that will 

have an effect on (SYSTEM) if the listed system is not operating according to design. It 

also lists the components of (system) whose failure can affect the operation of the 

(SYSTEM). Power supplies from K2 should be considered.
1-7

A1. Ability to predict or monitor changes in parameters associated with operation of the 

(SYSTEM) including: (CFR: 41.5 / 45.5)

Basis – The stem for A1 was revised by removing reference to exceeding design limits, 

and now includes any departure beyond normal operating characteristics. A1 lists the 

parameters monitored to verify proper operation of the system.

A2. Ability to (a) predict the impacts of the following on the (SYSTEM) and (b) based on

1.10 Emergency and Abnormal Plant Evolutions

Section 4 of the BWR catalog contains emergency plant evolutions (EPEs) and abnormal plant 

evolutions (APEs). An emergency plant evolution is any condition, event, or symptom which 

leads to entry into the plant-specific emergency operating procedures (EOPs). An abnormal 

plant evolution is any degraded condition, event, or symptom not directly leading to an EOP 

entry condition, but, nonetheless, adversely affecting a safety function. The listing of EPEs and 

APEs was developed to include those integrative situations crossing several plant systems or 

safety functions.

Table 3 contains a list of the emergency plant evolutions and the abnormal plant evolutions 

covered by this catalog.

Knowledge and Ability Stem Statements for Emergency and Abnormal Plant Evolutions

The information delineated within each emergency or abnormal plant evolution is organized into 

three types of knowledge and two types of ability. If there are no knowledge or ability statements 

following a stem statement there is no applicable K/A.

The applicable 10 CFR 55.41/ 55.43/ 55.45 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 and operating examinations. See Table 4, below.
1-9

1.11 Components

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

Section ES-205, “Procedure for Administering the General Fundamentals Examination

Program,” lists eight categories of components. 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 of the eight categories of components has a unique six digit code 

number and 10 CFR 55.41 (b) item number, for which additional knowledge statements are 

necessary. Components are delineated in Section 5 of the BWR catalog, and listed in Table 5 

below.
1-10

1.12 Theory

NUREG-1021, Section ES-205, “Procedure for Administering the General Fundamentals 

Examination Program,” lists theory items. General fundamental knowledge that underlies safe 

performance on the job is delineated in Section 6 of the BWR Catalog. These theory topics 

represent general fundamental concepts related to plant operation. Each theory topic has a 

unique six-digit code number. The applicable 10 CFR 41(b) item number is provided for Reactor 

Theory and Thermodynamics Theory.

1.13 Importance Ratings

Importance, in this context, considers direct and indirect effect 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 next to each knowledge and ability in the catalog. These ratings reflect average ratings of 

individual U.S. Nuclear Regulatory Commission (NRC) and utility panel members. 
1-11

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, and will be considered for deletion in a 

future revision to this catalog. (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.

• When referencing a system or component the associated indications, controls, and 

alarms that support the system function are applicable.

• K/A statement overlap in multiple sections is minimized. K/As 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 an RO license activity and will have N/A marked in the RO 

column.
1-12

• The K/As use generic terminology. If the specific design utilizes comparable but different 

terminology, the concept is still applicable. Examples of comparable terms include:

– Safety Injection Tanks (SIT) may be comparable to Core Flood Tanks (CFT)

– Engineering Safety Feature Actuation System (ESFAS) may be comparable to 

Engineering Safety Actuation System (ESAS)

– Auxiliary Feed Water (AFW) may be comparable to Emergency Feed Water 

(EFW)

– Component Cooling Water (CCW) may be comparable to interface Cooling 

Water (ICW)

• Subsystems, where applicable, are listed prior to each associated system.
