Your request should state that the NRC will not edit comment submissions to remove such information before making the comment submissions available to the public or entering the comment submissions into ADAMS. II. Further Information 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 ‘‘Software Unit Testing for Digital Computer Software Used in Safety Systems of Nuclear Power Plants’’ is temporarily identified by its task number, DG–1208. The DG–1208 is proposed Revision 1 of Regulatory Guide 1.171, ‘‘Software Unit Testing for Digital Computer Software Used in Safety Systems of Nuclear Power Plants’’ dated September 1997. This RG endorses ANSI/IEEE Std. 1008–1987, ‘‘IEEE Standard for Software Unit Testing,’’ issued in 1987 with the exceptions stated in the regulatory positions. ANSI/IEEE Std. 1008–1987 describes methods acceptable to the NRC staff for use in complying with the NRC’s regulations with respect to software testing for 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 DG is part of a series of 6 complimentary guides addressing the E:\FR\FM\22AUN1.SGM 22AUN1 Federal Register / Vol. 77, No. 163 / Wednesday, August 22, 2012 / Notices issue of digital software in power plant applications.
