applicants. Regulatory guides are not substitutes for regulations and compliance with them is not required. Methods and solutions that differ from those set forth in regulatory guides will be deemed acceptable if they provide a basis for the findings required for the issuance or continuance of a permit or license by the Commission.
The revised standard was approved by the American National Standards Committee N17, Research Reactors, Reactor Physics and Radiation Shielding, and its Secretariat.


Paperwork Reduction Act This regulatory guide contains information collection requirements covered by 10 CFR Part 50
It was subsequently approved and designated ANSI N398-1974 by ANSI on November 19, 1974.
and 10 CFR Part 52 that the Office of Management and Budget (OMB) approved under OMB control number 3150-0011 and 3150-0151, respectively. The NRC may neither conduct nor sponsor, and a person is not required to respond to, an information collection request or requirement unless the requesting document displays a currently valid OMB control number.


==B. DISCUSSION==
It should be recognized that ANSI N398-1974 covers only one limited aspect of quality assurance.
Reason for Revision Revision 1 to Regulatory Guide 2.3, issued in July 1976, endorsed the guidance provided in the American National Standards Institute (ANSI) N398-1974, Quality Verification for Plate-Type Uranium-Aluminum Fuel Elements." It was subsequently approved and designated ANSI N398-1974 by ANSI on November 19, 1974 and covers only one limited aspect of quality assurance. ANSI N398-1974 has been superseded and is no longer supported by the NRC staff. Revision 2 to Regulatory Guide 2.3 refers to the guidance in ANSI/ANS-15.2-1999, Quality Control for Plate-Type Uranium-Aluminum Fuel Elements (Ref. 4).
Background The NRC initially issued Regulatory Guide 2.3 in 1975 to provide guidance concerning procedures that the staff considered acceptable for complying with the agencys regulatory requirements in 10 CFR 50.34(a) (7). The original guide endorsed specific safety standards to provide guidelines for establishing and executing a program designed to verify the quality of plate-type uranium-aluminum fuel elements for use in research reactors. The American Nuclear Society (ANS) Subcommittee on the Operation of Research Reactors (ANS-15) rewrote ANSI N398-1974, issued it as ANSI/ANS-15.2-1999, and subsequently reaffirmed the standard in March 2009. The NRC staff believes that the foreword to ANSI/ANS-15.2-1999 (R2009) has several important assumptions about its use.


Harmonization with International Standards The International Atomic Energy Agency (IAEA) has established a series of safety standards constituting a high level of safety for protecting people and the environment. Relative to this regulatory guide, IAEA Safety Requirements publication NS-R-4, Safety at Research Reactors (Ref. 5), provides quality assurance requirements in sections 4.5-4.13, as part of an overall system of management and verification controls. While the NRC has an interest in facilitating the harmonization of standards used domestically and internationally, the NRC does not specifically endorse NS-R-4, and is only acknowledging that it may be useful as a reference for general information. The NRC could consider the use of the international standard in a licensing action following adequate justification and technical review.
ANSI N402, "Quality Assurance Program Guide lines for Research Reactors," which is currently being developed under Subcommittee ANS-15, is expected to provide overall guidance for establishing quality assurance programs for research reactors.

regulations as a requirement, then licensees and applicants must comply with that standard as set forth in the regulation. If the secondary reference has been endorsed in a regulatory guide as an acceptable approach for meeting an NRC requirement, then the standard constitutes a method acceptable to the NRC
staff for meeting that regulatory requirement as described in the specific regulatory guide. If the secondary reference has neither been incorporated by reference into NRC regulations nor endorsed in a regulatory guide, then the secondary reference is neither a legally-binding requirement nor a generic NRC approval as an acceptable approach for meeting an NRC requirement. However, licensees and applicants may consider and use the information in the secondary reference, if appropriately justified and consistent with current regulatory practice, consistent with applicable NRC requirements such as 10 CFR
50.59.
