Introduction This introduction is not part of IEEE Std 627-2010, IEEE Standard for Qualification of Equipment Use
5、d in Nuclear Facilities. The requirements for qualification of safety system equipment are mandated by regulatory documents including the Code of Federal Regulations (CFR) and various industry standards. Among them are the following: a) 10 CFR Part 50, Appendix A, General Design Criterion 2 (Design
6、Bases for Protection Against Natural Phenomena), General Design Criterion 4 (Environmental and Dynamic Effects Design Bases), and General Design Criterion 23 (Protection System Failure Modes). This requires that structures, systems, and components important to safety be designed to withstand the eff
7、ects of natural phenomena such as earthquakes, and to accommodate the effects of and to be compatible with the environmental conditions associated with normal operation, maintenance, testing, and postulated accidents, including loss-of-coolant-accidents. b) 10 CFR Part 50, Appendix B, Quality Assura
8、nce Criterion III (Design Control). This requires that design control measures be established and that such measures provide for verifying or checking the adequacy of design. One of the methods of design verification is by the performance of a suitable testing program. c) 10 CFR Part 50.55a, Codes a
9、nd Standards, Protection System. This requires that the protection system meet the requirements set forth in 4.4 of IEEE Std 279-1971 B11. d) ASME BPV-III, ASME Boiler and Pressure Vessel Code, Section III B3. e) Clause 4.7, Equipment Qualification, of IEEE Std 308, IEEE Standard Criteria for Class
10、1E Power Systems for Nuclear Power Generating Stations B12. f) Clause 4.6, Equipment Qualification, of IEEE Std 603, IEEE Standard Criteria for Safety Systems for Nuclear Power Generating Stations. g) Clause 3.3, Equipment Qualification, of ANSI/ANS-56.7-1978 (withdrawn 1997), Boiling Water Reactor
11、Containment Ventilation Systems. h) Clause 3.3, Component Performance Requirements, of ANSI/ANS-56.6-1986 (withdrawn 1996), Pressurized Water Reactor Containment Ventilation Systems. i) Clause 4.6, Isolation Barrier Environmental Provisions, of ANSI/ANS-56.2-1984 (withdrawn 1999), Containment Isolat
12、ion Provisions for Fluid Systems. Efforts on this standard were originally begun in late 1975 at the request of the IEEE Nuclear Standards Management Board. In 1977 a joint ASME/IEEE agreement established responsibility for qualification and quality assurance standards preparation. ASME accepted res
13、ponsibility for Quality Assurance and IEEE for qualification. In accordance with that agreement, IEEE completed the generic qualification standard which is this standard in 1980. This document provided high level approaches, criteria, guidance, and principles for qualification of both electrical and
14、 mechanical equipment that at that time appeared in no other industry standard. IEEE Std 627-1980 was later reaffirmed in 1996. In 1986, ASMEs Board on Nuclear Codes and Standards directed its Committee on Qualification of Mechanical Equipment (QME) to develop a standard for qualifying mechanical eq
15、uipment. This task was completed in several parts during the time frame from 1992 to 1994. Partly in response to this activity, IEEE Std 627 was withdrawn in 2002. Later although withdrawn, it was found that IEEE Std 627 was continuing to be used and referenced by many entities both in the US and ot
16、her countries including in ASMEs QME-1-2002 “Qualification of Active Mechanical Equipment Used in Nuclear Power Plants,” US NRCs NUREG-0800 Standard Review Plan Section 3.11 B38, at least one reactor vendors Design Certification Document (DCD), several iv Copyright 2010 IEEE. All rights reserved. in
17、ternational licensing documents, and elsewhere. As a result, in 2007, the IEEE Standards Board authorized Working Group 2.10 of Subcommittee 2 (Qualification) of the Power and Energy Societys Nuclear Power Engineering Committee to resurrect and update IEEE Std 627-1980 (R1996). This revision has inc
18、orporated the following improvements to reflect current practices and user needs: The resulting standard is an upper tier document to both IEEE Std 323TMand ASME QME-1. Allowance for Owner discretion to apply this standard to other safety system equipment and to facilities other than nuclear power g
19、enerating stations. The term design qualification has been replaced by equipment qualification or just qualification (because the term design qualification is not widely used). Deletions, additions to and updates in several of the definitions have been made (such as design qualification, equipment q
20、ualification, common mode and common cause failures, DBE Period of Operability, and margin). Minor changes in the names of Clause 5 and Clause 6 and rearranging of wording to match the clause titles have been made to facilitate future reference. An informative block diagram has been added to clarify
21、 the relationship between this standard and other qualification references. An informative annex clarifying various terms related to safety for possible use by facility Owners in determining when qualification should be invoked has been added. An informative bibliographical annex with a comprehensiv
22、e list of qualification references has been added. This standard was written and continues to serve as a general standard for qualification of all types of equipment, mechanical and instrumentation as well as electrical. It also establishes principles and procedures to be followed in preparing speci
23、fic equipment standards. Guidance for qualifying specific types of equipment may be found in various equipment-specific qualification standards (see Annex B). Equipment in nuclear facilities with required functions are required to meet or exceed performance requirements throughout its installed life
24、. This is accomplished by a disciplined program of qualification and quality assurance of design, production, installation, maintenance and surveillance. This standard is for the qualification section of the program only. Normal production testing and preoperational testing (i.e., functional testing
