Daily Rules, Proposed Rules, and Notices of the Federal Government
The NRC is soliciting stakeholder feedback on the following question--Should RG 1.168 be revised to endorse IEEE Std. 1012-2012 rather than IEEE Std. 1012-2004? IEEE Std. 1012-2012 expands the scope of IEEE Std. 1012-2004 to include verification and validation (V&V) task guidance for systems, software and hardware while IEEE Std. 1012-2004 only provides software V&V task guidance.

The NRC is issuing for public comment a draft guide in the NRC's “Regulatory Guide” series. This series was developed to describe and make available to the public such information 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.
The draft regulatory guide entitled “Verification, Validation, Reviews, and Audits for Digital Computer Software used in Safety Systems of Nuclear Power Plants” is temporarily identified by its task number, DG-1267. The DG-1267 is proposed Revision 2 of RG 1.168, “Verification, Validation, Reviews, and Audits for Digital Computer Software used in Safety Systems of Nuclear Power Plants” dated February 2004.
This RG endorses with clarifications and exceptions, the consensus practices for complying with NRC regulations promoting the development of, and compliance with, software verification and validation reviews and audits described in IEEE Std. 1012-2004, “IEEE Standard for Software Verification and Validation” and IEEE Std. 1028-2008, “IEEE Standard for Software Reviews and Audits.” These 2 IEEE standards describe methods acceptable to the NRC staff for use in complying with the NRC's regulations with respect to software verification and auditing of digital computer software used in the safety systems of nuclear power plants. In particular, the methods are consistent with part 50 of Title 10 of the Code of Federal Regulations (10 CFR), “Domestic Licensing of Production and Utilization Facilities,” Appendix A, “General Design Criteria for Nuclear Power Plants,” General Design Criterion 1, “Quality Standards and Records,” which requires, in part, that a quality assurance program be established and implemented to provide adequate assurance that systems and components important to safety will satisfactorily perform their safety functions.
This draft regulatory guide is part of a series of 6 complimentary guides addressing the issue of digital software in power plant applications. The following is a complete list of all 6 of the DGs:
