Start Preamble

The Nuclear Regulatory Commission (NRC) has issued a revision of a guide in its Regulatory Guide Series. This series has been developed to describe and make available to the public such information as methods acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques used by the staff in its review of applications for permits and licenses, and data needed by the NRC staff in its review of applications for permits and licenses.

Revision 1 of Regulatory Guide 1.168, “Verification, Validation, Reviews, and Audits for Digital Computer Software Used in Safety Systems of Nuclear Power Plants,” provides guidance to licensees and applicants on methods acceptable to the NRC staff for complying with the NRC's regulations on verification, validation, reviews, and audits for digital computer software used in safety systems of nuclear power plants. This regulatory guide endorses, with certain exceptions, two standards of the Institute of Electrical and Electronics Engineers: IEEE Std 1012-1998, “IEEE Standard for Software Verification and Validation,” and IEEE Std 1028-1997, “IEEE Standard for Software Reviews and Audits.”
