# AGENCY:

Nuclear Regulatory Commission. 

# ACTION:

Notice of proposed supplements for public comment.

# SUMMARY:

The Nuclear Regulatory Commission (NRC) has issued for public comment draft supplements to Revision 9 of NUREG-1021, “Operator Licensing Examination Standards for Power Reactors,” and to Revision 2 of NUREG-1122 [and -1123] “Knowledge and Abilities Catalog for Nuclear Power Plant Operators: Pressurized [Boiling] Water Reactors.” These NUREGs provide policy and guidance for the development, administration, and grading of examinations used for licensing operators at nuclear power plants pursuant to the Commission's regulations in 10 CFR Part 55, “Operators” Licenses.” NUREG-1021 also provides guidance for maintaining operators' licenses, and for the NRC to conduct requalification examinations, when necessary. 

The draft supplement to Revision 9 of NUREG-1021 includes a number of minor changes that are intended to: (1) Clarify licensed operator medical requirements, including the use of prescription medications; (2) clarify the use of surrogate operators during dynamic simulator scenarios; (3) clarify the selection process for generic knowledge and ability (K/A) statements; (4) qualify the NRC review of post-examination comments; (5) provide additional guidance for maintaining an active license (watchstander proficiency) and license reactivation; and (6) conform with proposed updates to NUREGs-1122 and -1123, which are concurrently available for public comment. The proposed changes are summarized in the Record of Proposed Changes, and identified by highlight/redline and strikeouts. 

The draft supplements to NUREGs-1122 and -1123 propose to reword and reorganize Section 2, “Generic Knowledge and Abilities,” and add a new K/A topic to Section 4, “Emergency/Abnormal Plant Evolutions,” to address generator voltage and electric grid disturbances. The proposed changes are summarized in the Record of Changes, and identified by highlight/redline and strikeouts.
