17、word is not a part of American National Standard “Non-Real-Time, High-Integrity Software for the Nuclear IndustryDeveloper Requirements,” ANSI0ANS-10.7-2013.!The purpose of this standard is to provide quality assurance requirements fornon-real-time, high-integrity software developed for nuclear indu

18、stry applica-tions. The standard does not recommend a specific approach to software devel-opment but does recommend that quality assurance activities be carried out inparallel with software development. For a specific project, the project sponsorshould determine the level of the verification and val

19、idation effort to be applied.Compliance with this standard does not automatically guarantee compliancewith any other standard.This standard complements the followingANS-10 standards relating to computerprogram development:ANSI0ANS-10.2-2000 R2009!, “Portability of Scientific and EngineeringSoftware”

20、;ANSI0ANS-10.3-1995 W2005!, “Documentation of Computer Software”;ANSI0ANS-10.4-2008, “Verification and Validation of Non-Safety-Related Sci-entific and Engineering Computer Programs for the Nuclear Industry”;ANSI0ANS-10.5-2006 R2011!, “Accommodating User Needs in Scientific andEngineering Computer S

21、oftware Development.”This standard builds upon NUREG0CR-6263, “High-Integrity Software for Nu-clear Power Plants: Candidate Guidelines, Technical Basis and Research Needs,”which was prepared for the U.S. Nuclear Regulatory Commission to assist withdevelopment of a technical basis for regulatory posi

22、tions related to the use ofhigh-integrity software in nuclear power plants. NUREG0CR-6263 was the re-sult of a comprehensive review of the present state of software engineeringprocesses and design attributes. While the focus of that effort was on real-time,high-integrity software, this standard focu

23、ses on non-real-time, high-integritysoftware, such as for design and analysis. Therefore, the requirements of thisstandard were carefully adapted from the former and new requirements devel-oped and added for model development and validation, which are key aspects ofanalytical, non-real-time software

24、computer codes!. NUREG0CR 6263 and NUREG0CR-5930, NIST SP 500-204, “High-Integrity Software Standards and Guide-lines,” were developed for application to nuclear power plants, and therfore, thisstandard is primarily applicable to nuclear power plants and other nuclearfacilities and operations with s

25、imilar high consequences and hazards.In addition, an effort has been made to maintain consistency in terminology andconcepts with various software standards being developed under the sponsorshipof the Institute of Electrical and Electronics Engineers and to identify areas ofdisagreement.This standar

26、d might reference documents and other standards that have beensuperseded or withdrawn at the time the standard is applied. A statement hasbeen included in the references section that provides guidance on the use ofreferences.This standard does not incorporate the concepts of generating risk-informed

27、insights, performance-based requirements, or a graded approach to quality as-surance. The user is advised that one or more of these techniques could enhancethe application of this standard. For example, the software requirements of thisstandard, which have been developed for high-consequence applica

28、tions, could beappropriately tailored or graded for applications of lower consequence.iThis standard has been written by Working Group ANS-10.7 of the AmericanNuclear Societys Standards Committee.
