To date, the HDPE pi

10、ping at Catawba Nuclear Station has performed well and has proven to be a cost effective way to address the corrosion issues in the stations service water piping. HOPE piping is durable, requires very low maintenance and has lower overall cost than metallic piping. As a result of the success at Cata

11、wba Nuclear Station, Duke Energy and other utilities have sought to use HDPE piping in buried ASME Section III, Class 3 service water system applications. In 2008, the Nuclear Regulatory Commission (NRC) approved a Relief Request for the AmerenUE Callaway Nuclear Plant for the use of HDPE in buried

12、sections of its essential service water system. The HDPE piping in the Callaway essential service water system has been in operation since late 2008. In 2009, the NRC approved a Relief Request for Catawba Nuclear Station for use of HDPE in buried sections of its nuclear service water system. Section

13、s of the HDPE piping in the Catawba nuclear service water system have been in operation since late 2010. It is the desire of ASME, Utilities, Regulators, the HDPE industry, Architect-Engineer (AE) firms and Constructors to develop a technology roadmap, which will support technology strategy and plan

14、ning goals to achieve safety, reliability, economic and research and development. Achieving a broad acceptance of HOPE pipe for use in water systems at nuclear plants will require collaboration and sponsorship from industry, regulators, government entities, research organizations, domestic and inter

15、national associations and individuals.

19、lic piping systems in safety related and non-safety related service water in nuclear power plants are prone to tuberculation, corrosion and leaks, and require replacement, in some instances in less than ten years of service. Non-safety related HDPE piping systems currently installed in nuclear power

20、 plants have proved to be reliable since 1996. Several utility owners have successfully installed HDPE piping. The owners would then seek approval by the Nuclear Regulatory Commission (NRC) through a Relief Request process. The NRC Relief Request process normally requires one year to complete. Devel

21、opment of and NRC approval of ASME Boiler and Pressure Vessel Code rules for use ofHDPE would be very beneficial to all parties in the nuclear power industry. Much research and testing has been undertaken and is continuing in support ofHDPE use for nuclear power piping. The ASME HDPE Roadrnap propos

22、es strategies which will be used to develop appropriate rules to impart science and structure to the HDPE piping application in nuclear service. The Roadmap identifies critical technologies and infrastructure gaps, barriers and opportunities, and recognizes and prioritizes research and development p

23、rograms and new technology needs 1. Among the issues identified for resolution are: piping system design requirements and engineering properties; pipe fusion procedures; fusion integrity analyses and testing procedures development; pipe performance requirements; volumetric examination methods and de

24、termination of acceptable material flaws applicable to U.S. and international standards and procedures. The execution of these strategies requires technical and financial commitment by the nuclear industry operators and suppliers as well as academia and regulators. Immediate financial and technical

25、commitments are needed to execute several of these strategies. HDPE pipe replacement saves money and enhances safety. It is easy to install, it is corrosion free, durable and not subject to fouling. The ASME HDPE Roadmap is the first step toward establishing a disciplined structure toward creating C

26、ode rules to address pressing industrys needs. The next step will focus on follow-up activities dealing with executing current needs, and simultaneously developing future endeavors. v STP-NU-057 ASME HDPE Roadmap STAKEHOLDERS The ASME HDPE Roadmap stakeholders are members of Section Ill Stakeholders

29、trategy for advancing the rules that will govern the technical aspects of the design, installation, operation and inspection of HDPE piping systems in nuclear power plants. Scientifically and statistically based rules will instill safety and confidence, and these rules are in the best interest of th

30、e nuclear industry, re!:,rulators, the HOPE industry and the general public. The ASME HDPE Roadrnap strategy aims to identify gaps, remove roadblocks, facilitate necessary research and resolve concerns. The Roadmap is intended to lead to the development of Code rules, which can subsequently be endor

31、sed by the regulator (NRC) for generic use and application to facilitate licensing without the need for an application specific Relief Request. The strategies and plans of the ASME HOPE Roadrnap (this document) attempt to identify and characterize the industry and regulators concerns, establish rele

32、vant justifications for desired research, and challenge researchers and providers to deliver solutions 2. The Roadrnap identifies codes and standards related to HDPE piping and may require modification to address HDPE piping applications in nuclear service. This document does not address the process

33、, or Roadmapping. The technology Roadmapping represents a powerful technique to support technological management and planning, especially to explore and communicate dynamic interactions between resources, organizational goals and environment changes 3. The Technology Roadrnapping process provides a

34、way to develop, organize and present information about critical requirements and desirable performance of objectives that must be achieved at the planned time 2. This report is structured as follows: It describes the research and networking leading to the development of the road!map strategies and p

35、lans It identifies major issues of concerns, gaps and roadblocks. It clarifies issues by describing their background and lays out options for technical solutions. The roadmap summarizes and prioritizes research projects deemed important to receive technical solutions. lt displays projects schedule a

36、nd mjlestones in a Gantt style chart and tabulated form. STP-NU-057 ASME HDPE Roadmap 2 THE HOPE PIPE TECHNOLOGY ROADMAP The objective of the ASME HDPE Roadmap is to lead the industry toward achieving its principal goal, which is to advance and increase the use of HDPE piping in nuclear power plants

37、. This can be achieved through the development of Code rules following proposed plans and strategies which will result in a structured and safe application. Proposed plans and strategies will serve as instruments to identify gaps and obstacles, resolve technical issues and forecast and identify rese

38、arch needed to establish an acceptable basis to support the use ofHDPE piping in nuclear plant applications. Several projects to replace worn-out metal pipes and or install new piping systems are underway. The use of HDPE piping in nuclear power plants will promote safety, durab ility and cost savin

39、g in construction and operation. The current practice to license an HDPE piping system in nudear power plants is through an application to the Nuclear Regulatory Commission (NRC) for a Relief Request. This process is complex and time consuming. Instead, ASME has developed this Roadmap which eventual

40、ly will lead to: Researching and fmding solutions to current technical issues. Developing a comprehensive Code that is specific and succinct, and which precludes the need for extensive licensing activities required for NRC acceptance. A questionnaire was developed and e-mailed to survey participants

41、 to collect information about real and perceived gaps and obstacles associated with current and future use of HDPE piping in nuclear water service applications. The composition of the survey participants were mainly members of ASME Section III Working Group on HDPE Research and Development and other

42、 contributors to ASME Sections II, 1X and XI. Additionally, input was requested from several members of the international conununity. Ensuing participant response, the questionnaire was followed by a telephone interview to discuss responders input. The total number of responders was 21 , or 70%, of

43、those invited to participate. The questionnaire or survey identified gaps, roadblocks, technical issues and proposed solutions. The responders provided a wealth of information relating to actual and perceived issues facing the continued success of HDPE piping in nuclear service. Participant input co

44、vered a wide range of subjects concerning applied engineering, product performance, regulatory, financing, etc. The table below summarizes the participant input. 2 ASME JIDPE Roadmap STP-NU-057 Table 1 - Summary of Survey Responses General Category Issues and/or Needs Category 1- Develop a clear pat
