14、 for Nuclear Qualified Electrical Equipment Abstract The IEEE Standards Association (IEEE-SA) and the IEEE Nuclear Power Engineering Committee (NPEC) formed the NPEC Conformity Assessment Steering Committee (NPEC CASC) in September 2014. The NPEC CASC boasts an outstanding constituency of members in
15、 the domain of nuclear power technology who share a common vision to accelerate IEEE standards adoption through conformity assessment and certification programs. Participants in NPEC CASC include representatives from device manufacturers, test laboratories and the end-user community. IEEE-SA Conform
16、ity Assessment Program (ICAP) creates and implements initiatives that drive and accelerate certification programs throughout industry addressing a broad range of technologies. ICAP, along with the NPEC CASC, is looking into development of a conformity assessment program to support IEEE Std 323 and o
17、ther related standards. This paper will provide readers with an in-depth look at the current state of equipment qualification in the nuclear industry globally. It will also present the benefits of a comprehensive certification program. It will provide a varied perspectives ranging from a utility, pl
18、ant owner, and manufacturer to regulators. The following are considered key activities of the NPEC CASC: Recommend and consolidate program structure for the certification of Class 1E devices Recommend and establish compliance levels Provide guidance on test methods Recommend and establish test lab r
19、equirements and audit processes Recommend and establish test tool validation Act as certification program advocates Validate Test Plan/Report template Proposed IEEE Certification for Nuclear Qualified Electrical Equipment The Institute of Electrical and Electronic Engineers (IEEE) is the worlds larg
20、est professional association and a premier developer of global standards. Worldwide, IEEE has more than 425,000 members spanning more than 160 countries. The IEEE is composed of 45 Technical Societies that are active in 160 countries. Annually IEEE has at least 1,600 conferences and in its history h
21、as issued more than 3.7million technical documents. The standards development organization within IEEE is the IEEE Standards Association (IEEE-SA). IEEE-SA develops standards that are globally recognized, in an environment that operates in an independent community and has an open standards process.
22、This helps ensure the development of independent and consensus standards, which can be broadly applied and adopted. The IEEE-SA process has resulted in the issuance of over 900 active standards that have been developed by more than 20,000 standards developers located on every continent. This process
23、 is widely recognized and respected, and aligns with 2 Copyright 2015 IEEE. All rights reserved. the World Trade Organization (WTO) and Open Stand principles. The process is transparent, open and cooperative, resulting in openness and consensus standards that are based on current scientific and tech
24、nological knowledge. The IEEE Nuclear Power Conformity Assessment Program is being developed collaboratively by the IEEE Nuclear Power Engineering Committee (NPEC) and the IEEE-SA Conformity Assessment Program (ICAP). NPEC is a committee consisting of more than 300 members operating under the IEEE P
25、ower and Energy Society. This partnership will implement certification program initiatives for both Class 1E (IEEE) and Important to Safety (IEC) components to nuclear qualification standards. Class 1E and Important to Safety components are crucial to operation and safe shutdown of nuclear power gen
26、erating stations. In 2002, IEEE and the International Electrotechnical Commission (IEC) entered into an agreement to allow the adoption of IEEE standards by IEC. In 2008, this agreement was expanded to allow the joint development of standards. The agreement now allows the two organizations to work c
27、ollaboratively to develop new or revise existing IEEE or IEC standards and issue them as a dual logo document. Draft Standard IEC/IEEE P60780-323 Nuclear facilitiesElectrical equipment important to safetyQualification represents the most significant dual logo standard addressing qualification of ele
28、ctrical equipment within each organization. The standard is applicable to electrical equipment important to safety and its interfaces. This includes components that are necessary to perform a safety function, or whose failure could adversely affect the safety function of other equipment thus diminis
29、hing plant safety. The IEC/IEEE dual logo document now represents the only qualification standard for electrical equipment that is both a consensus document and has worldwide acceptance and recognition. The IEEE Certification program will apply to all IEEE 323 qualified components, including daughte
30、r standards. The family of standards will include the following: a) IEEE Std 323Equipment Qualification b) IEC/IEEE 60780-323Equipment Qualification c) IEEE Std 334Qualification of Motors d) IEEE Std 382Qualification of Actuators e) IEEE Std 383Qualification of Cables and Splices f) IEEE Std 344Seis
31、mic Qualification g) IEEE Std 627Qualification of Safety Equipment h) IEEE Std 572Qualification of Connectors i) IEEE Std 650Qualification of Battery Chargers/Inverters j) IEEE Std 649Qualification of Motor Control Centers k) IEEE Std 1682Qualification of Fiber Optic Cables In the second decade of t
32、he 21stcentury, the nuclear power industry is facing new challenges. Both countries and companies that did not participate in the first generation of nuclear power plants are now taking leadership positions in the development of the next generation of nuclear power plants. The challenge to the nucle
33、ar industry is how to effectively transfer knowledge and lessons learned onto this new generation of nuclear engineers. One aspect of nuclear power implementation that has withstood the test of time is IEEE standards. IEEE standards have been successfully used as a basis for qualification of equipme
34、nt for more than 40 years. As this new era begins, the effective use of IEEE standards will help continue to provide assurance 3 Copyright 2015 IEEE. All rights reserved. that new reactors are designed, built, and maintained to the highest levels for continued safe and reliable operation. The resurg
35、ence of nuclear power is being driven by the increase in the global demand for power. This tremendous need for power is also being balanced by demands for a cleaner environment. As a result, more and more countries are looking toward nuclear power as the solution. The current designers of nuclear po
36、wer plants must not only ensure that nuclear safety is maintained, but that plants are designed, constructed, licensed, and maintained economically. The huge cost overruns that plagued the first generation must be avoided with this new generation of plants. Due to the significant advancements in tec
37、hnology over the past forty years, the new generation of plants will have more advanced safety features than previous designs. The advancements in technology have also led to different technical challenges. Conformity Assessment could be a viable method to help address these challenges. Globally, th
38、e nuclear industry has always had to deal with counterfeit, fraudulent, and sub-standard parts. Ensuring that issues such as these were addressed was at the heart of why qualification standards were developed more than 40 years ago. But as technology has changed to the benefit of better plant and eq
39、uipment designs, it has also introduced new challenges to address the following: Counterfeit parts can be more easily built and they are more difficult to detect. Components have become more complex and have new failure modes that must be evaluated. Strict adherence and compliance with qualification
40、 standards is more important than ever due to common mode failure and the implications on a greater number of operating units. In 2008, the United States Nuclear Regulatory Commission (USNRC) issued Information Notice 2008-04 to inform nuclear power plant owners of the potential for counterfeit part
41、s entering the supply chain 4.1The information notice was issued due to then two (2) recent events. In 2007, Plant Hatch discovered that the stator cooling water stop check valves were counterfeit. One valve was installed in the plant and one was in the warehouse. The notice further stated that the
42、USNRC was aware that the U.S. Consumer Product Safety Commission (CPSC) had announced a recall of counterfeit circuit breakers labeled as “Square D“. The recalled circuit breakers labeled “Square D” were manufactured in China and distributed from 2003 through 2006. In 2012, the nuclear industry expe
43、rienced the most significant occurrence of counterfeit parts and fraudulent quality assurance documents to date. The investigations that began in late 2012 eventually determined that over a 10-year period more than 8,000 parts, that affected 11 nuclear power units, had been used. The investigations
44、revealed the doctoring of test reports, falsification of certificates, and misrepresentation of test data. These types of incidences resulted in significant costs, time delays, and loss of public trust. The corrective actions forced modifications in construction schedules, shutdown of operating unit
45、s for component replacement, and added expenditure to institute independent verification. (Refer to 1, 2, 3, and 5) 1Numbers in brackets refer to references found at the end of this document in the “Citations” section. 4 Copyright 2015 IEEE. All rights reserved. Counterfeit and fraudulent parts have
46、 been identified as affecting electronic components, circuit breakers, relays, fuses, fan motors, and control cables. The impact that counterfeit and fraudulent parts may have on safety and non-safety related equipment poses a significant safety and economic concern for the nuclear power industry. T
47、he potential for counterfeit and fraudulent parts to enter the nuclear supply chain will continue to grow. In the decades to come, more worldwide suppliers with no nuclear experience will enter the market. This growth will be driven by a need to support the growing demand for components to aid in ne
48、w power plant construction. Failures in design, qualification testing, or the validity of test results have a greater impact than ever on the nuclear power industry. Deficiencies in any of these areas can result in a large number of nuclear units being temporarily or permanently shut down. Entire co
49、untries can be adversely affected, and the economic and social cost would be devastating. The compliance, and validated compliance, with IEEE standards has never been more needed than it is today. To address these issues, the IEEE nuclear power certification program is being developed to support equipment vendors who demonstrate compliance to IEEE standards and meet the requirements of IEEEs qualification standards. Once a product is IEEE certified, it is not only marked and identified as IEEE certified, but it becomes tra
