Revision to regulatory guide; issuance.
The U.S. Nuclear Regulatory Commission (NRC) is issuing a revised regulatory guide (RG), Revision 1 of RG 1.170, “Test Documentation for Digital Computer Software Used in Safety Systems of Nuclear Power Plants.” This RG endorses the Institute of Electrical and Electronic Engineers (IEEE) Standard 829-2008, “IEEE Standard for Software and System Test Documentation” with the clarifications and exceptions stated in Section C, “Staff Regulatory Guidance” of the RG. IEEE Std. 829-2008 describes methods that the NRC considers acceptable for use in complying with NRC regulations for developing test documentation and design quality in the software used in safety systems of nuclear power plants.

The NRC is issuing a revision to an existing guide in the NRC's “Regulatory Guide” series. This series was developed to describe and make available to the public information such as methods that are acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses.
Revision 1 of RG 1.170 was issued with a temporary identification as Draft Regulatory Guide, DG-1207 on August 22, 2012 (77 FR 50720) for a 60-day public comment period. The public comment period closed on November 23, 2012. Multiple public comments were received and addressed by the NRC staff. These comments and the NRC staff responses are available in ADAMS under Accession number ML13003A209.
Revision 1 of RG 1.170 endorses IEEE Std. 829-2008, “IEEE Standard for Software and System Test Documentation” with the exceptions stated in the Section C “Staff Regulatory Guidance” of the RG. IEEE Std. 829-2008 describes methods that the NRC considers acceptable for use in complying with NRC regulations for developing test documentation and design quality in the software used in safety systems of nuclear power plants. In particular, the methods are consistent with the GDC in Appendix A to part 50 of Title 10 of the Code of Federal Regulations (10 CFR), “Domestic Licensing of Production and Utilization Facilities” and the criteria for quality assurance programs in Appendix B to 10 CFR part 50 as they apply to the documentation of software testing activities. The criteria in Appendices A and B of 10 CFR part 50 apply to systems and related quality assurance processes, and the requirements extend throughout the life cycle of the protection system especially when those systems include software. There are further requirements for software testing which can be found in the documentation retention and handling section of 10 CFR part 21.51, “Maintenance and Inspection of Records.”
This RG is one of six RG revisions addressing computer software development and use in safety related systems of nuclear power plants. These RGs were developed by the Office of Nuclear Regulatory Research, Division of Engineering (RES/DE) with the assistance of multiple individuals in the Office of New Reactors, Division of Engineering (NRO/DE); Office Nuclear Reactor Regulation, Division of Engineering (NRR/DE); and the Office of Nuclear Security and Incident Response, Division of Security Policy (NSIR/DSP). The six interrelated RGs are:
1. Revision 2 of RG 1.168, “Verification, Validation, Reviews, and Audits for Digital Computer Software used in Safety Systems of Nuclear Power Plants,” issued for public comment as DG-1267. The package for Rev. 2 of RG 1.168 is in ADAMS at Accession No. ML12236A132.
2. Revision 1 of RG 1.169, “Configuration Management Plans for Digital Computer Software used in Safety Systems of Nuclear Power Plants,” issued for public comment as DG-1206. The package for Rev. 1 of RG 1.169 is in ADAMS at Accession No. ML12354A524.
3. Revision 1 of RG 1.170, “Test Documentation for Digital Computer Software used in Safety Systems of Nuclear Power Plants,” issued for public comment as DG1207. The package for Rev. 1 of RG 1.170 is in ADAMS at Accession No. ML12354A531.
4. Revision 1 of RG 1.171, “Software Unit Testing for Digital Computer Software Used in Safety Systems of Nuclear Power Plants,” issued for public comment as DG1208. The package for Rev. 1 of RG 1.171 is in ADAMS at Accession No. ML12354A534.
5. Revision 1 of RG 1.172, “Software Requirements Specifications for Digital Computer Software used in Safety Systems of Nuclear Power Plants,” issued for public comment as DG-1209. The package for Rev. 1 of RG 1.172 is in ADAMS at Accession No. ML12354A538.
6. Revision 1 of RG 1.173, “Developing Software Life Cycle Processes for Digital Computer Software used in Safety Systems of Nuclear Power Plants,” issued for public comment as DG-1210. The package for Rev. 1 of RG 1.173 is in ADAMS at Accession No. ML13008A338.
Issuance of this revised RG does not constitute backfitting as defined in 10 CFR 50.109 (the Backfit Rule) and is not otherwise inconsistent with the issue finality provisions in 10 CFR part 52. As discussed in the “Implementation” section of this RG, the NRC has no current intention to impose this RG on holders of current operating licenses, early site permits or combined licenses, unless this final regulatory guide is part of the licensing basis for the facility. The NRC may apply this revised RG to applications for operating licenses, early site permits and combined licenses docketed by the NRC as of the date of issuance of the final RG, as well as to future applications for operating licenses, early site permits and combined licenses submitted after the issuance of the RG. Such action does not constitute backfitting as defined in 10 CFR 50.109(a)(1) and is not otherwise inconsistent with the applicable issue finality provision in 10 CFR part 52, inasmuch as such applicants or potential applicants are not within the scope of entities protected by the Backfit Rule or the relevant issue finality provisions in part 52.
This RG is a rule as designated in the Congressional Review Act (5 U.S.C. 801-808). However, the Office of Management and Budget (OMB) has not found it to be a major rule as designated in the Congressional Review Act.
Dated at Rockville, Maryland, this 19th day of July, 2013.
