they do not want to be publicly disclosed in their comment submissions. Your request should state that the NRC does not routinely edit comment submissions to remove such information before making the comment submissions available to the public or entering the comment into ADAMS.
II. Additional Information The NRC is issuing for public comment a draft guide in the NRCs Regulatory Guide series. This series was developed to describe methods that are acceptable to the NRC staff for implementing specific parts of the agencys regulations, to explain techniques that the staff uses in evaluating specific issues or postulated events, and to describe information that the staff needs in its review of applications for permits and licenses.
This proposed Revision 2 to RG 1.87, entitled Acceptability of ASME Code Section III, Division 5, High Temperature Reactors, is temporarily identified by its task number, DG1380
ADAMS Accession No. ML21091A276.
The staff is also issuing for public comment a draft regulatory analysis ADAMS Accession No. ML21091A277, and draft NUREG2245, Technical Review of the 2017 Edition of ASME
Section III, Division 5, High Temperature Reactors, ADAMS
Accession No. ML21223A097 that documents the NRC staffs review of the 2017 Edition of ASME Section III, Division 5, certain portions of the 2019
Edition, and associated Code Cases N
861 and N862. Code Cases N872 and N898 the Alloy 617 Code Cases, approved by ASME in 2020, are not included in this review and are being considered for endorsement in a parallel effort.
The NRC published Revision 1 of RG
1.87, Guidance for Construction of Class 1 Components in ElevatedTemperature Reactors, in June 1975 to provide licensees and applicants with agency-approved guidance for complying with paragraph 50.55a of title 10 of the Code of Federal Regulations 10 CFR Codes and standards, and General Design Criterion 1, Quality Standards and Records. The guide described interim licensing guidelines to aid applicants in implementing these requirements with respect to ASME Class 1 components operating at elevated temperatures.
Specifically, the guide approved, with conditions, the initial versions of five Code Cases namely, Code Cases 1592
0, 15930, 15940, 15950, and 15960.
These five Code Cases are the precursors to the other iterations of ASMEs high temperature construction rules: Code

Cases N47 through N51; ASME Code, Section III, Subsection NH; and currently ASME Code, Section III, Division 5. The current version of RG
1.87 Revision 1 does not reflect the changes and updates with respect to modern design, fabrication, inspection, testing, and overpressure provisions among others addressed by the aforementioned Code iterations, research, and operating experience.
This revision Revision 2 updates the guidance to endorse, with conditions, the 2017 Edition of ASME Code Section III, Division 5, as a method acceptable to the staff for the materials, mechanical/structural design, construction, testing, and quality assurance of mechanical systems and components and their supports of hightemperature reactors. This revision of the guide also addresses the acceptability of the Code Cases N861
and N862, which are related to Division 5 of the ASME Code, Section III. Draft NUREG2245 provides the technical basis for NRC staff positions stated in the DG, including proposed exceptions and limitations on the use of Division 5. Additionally, this revision adds an appendix to the RG namely Appendix A, High Temperature Reactor Quality Group Classification, which provides guidance for the quality group classification of components in non-light water reactor designs.
III. Backfitting, Forward Fitting, and Issue Finality DG1380 and NUREG2245, if finalized, would not constitute backfitting as defined in 10 CFR 50.109, Backfitting, and as described in NRC
Management Directive MD 8.4, Management of Backfitting, Forward Fitting, Issue Finality, and Information Requests ADAMS Accession No.
ML18093B087; constitute forward fitting as that term is defined and described in MD 8.4; or affect the issue finality of any approval issued under 10
CFR part 52, Licenses, Certificates, and Approvals for Nuclear Power Plants.
The guidance would not apply to any current licensees or applicants or existing or requested approvals under 10 CFR part 52, and therefore its issuance cannot be a backfit or forward fit or affect issue finality. Further, as explained in DG1380, applicants and licensees would not be required to comply with the positions set forth in DG1380.
