**AGENCY:**
Nuclear Regulatory Commission.
**ACTION:**
Draft report; request for comment.
**SUMMARY:**
The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment a draft NUREG, NUREG-1478, Revision 3, “Operator Licensing Examiner Standards for Research and Test Reactors.” This draft NUREG establishes the policies, procedures, and practices for the development, administration, and grading of written examinations and operating tests used for examining licensees and applicants for reactor operator and senior reactor operator licenses at research and test reactor facilities. It also provides procedures and guidance for maintaining operators' licenses and for the NRC to conduct requalification examinations when necessary. Draft NUREG-1478, Revision 3, introduces electronic systems and technology, includes current research and test reactor regulations, adjusts grading criteria for accuracy, and streamlines the examination standards by organizing them in topic-based sections for ease of use.

**II. Discussion**
Draft NUREG-1478, Revision 3, improves research and test reactors operator licensing current processes and clarifies guidance as needed. Draft NUREG-1478, Revision 3 provides policies, procedures, and practices for the development, administration, and grading of examinations used for licensing operators at research and test reactors under the NRC's regulations in part 55 of title 10 of the *Code of Federal Regulations,* “Operators' Licenses.” This draft NUREG also provides guidance for maintaining operators' licenses and for the NRC to conduct requalification examinations when necessary. The NRC is issuing the draft NUREG to (1) incorporate the use of electronic systems and technology for application submittals and supporting facility documentation, (2) include current regulatory requirements pertaining to operator licensing at research and test reactors, (3) adjust grading criteria for the written examination to provide consistent and accurate grading, and (4) reorganize the examination standards to provide a streamlined topic-based approach.
**III. Executive Order (E.O.) 12866**
The Office of Information and Regulatory Affairs determined that this draft NUREG is not a significant regulatory action under E.O. 12866.
