  1. Nuclear Standards for Polymeric Piping Aaron Forster, NIST            Engineering Laboratory NIST, MS 8615 100 Bureau Drive Gaithersburg, MD 20899 (301) 975-8701 Email: aaron.forster@nist.gov

  2. NESCC HDPE Status: • PPTG report released in January 2013 • Held a workshop on February 28, 2013 to discuss merger of NESCC and ASME HDPE Roadmaps • Continue to Formalize Roadmap with communication between ASME and NRC • Held meeting at NRC on March 14, 2013 to discuss input on short term priorities. • Planning 2nd workshop for April 18, 2013 to further progress in creating a “Joint HDPE Roadmap” plan

  3. ASME Roadmap Implementation Planning Issues Standards Development Endorsement Resolutions 2 5 1 3 4 • Identify projects: utilize ASME’s HDPE Roadmap, NESCC’s report & other sources • Develop project scope • Establish tasks, schedule & budgets • Identify target code case or standard • Identify funding • Coordinate with other SDO’s, & government entities. • Obtain regulatory buy- in on the plan forward • Capturing Issues from Regulators and industry • Prioritization of Issues/concerns with input from NRC, DOE, SDOs and industry • Confirm Regulatory acceptance of priorities • Solicit Contracts with R&D Entities • Oversee R&D Projects • Review Results • Share Final Findings and Outcome with Committees/NRC • Confirm regulatory agreement of Issue Resolution • Standards development and writing • Revise or create Technical Concerns, Code Cases or Standards • Consensus process • Adoption to the Code • NRC participation in first 4 phases lead to standards endorsement • Obtain NRC endorsement of new or modified code cases or standards

  4. HDPE Roadmap Workshop EPRI Headquarters February 28, 2013 • Attendees: • DOE, NRC, ASME, ASTM, EPRI, NIST • Objective: • Coordinate the NESCC and ASME “Joint Roadmap” efforts. Let’s work from one template. • Identify potential short and long term R&D projects, deliverables, and standards impacts. • Prioritize projects • Identify current efforts on R&D, both confirmatory and new research • Deliverables: • Consensus Roadmap with basic prioritization • Develop an understanding of current efforts and future research efforts required • Methodology to track progress at ASME • Methodology to prioritize projects and sub-tasks • Strategy for Stakeholder engagement (Future Meeting)

  5. Move away from a numbered list to an actionable plan…. NESCC 10-013 – HDPE use by Catawba Nuclear Station, Steve Lefler, Duke Energy NRC Issues Regarding the use of HDPE piping in safety-related nuclear applications, Use of HDPE for Power Plant Piping Systems Workshop, June 7-10, 2010 North Carolina STP-NU-YYY ASME Code Development Roadmap for HDPE Service Pipe in Nuclear Service, under revision NESCC Polymeric Pipe Task Group Report, 2012, balloted for draft

  6. Prioritization: • Prioritize according to Code Deliverables: • Short term (under 3 years) • Specify as “A” priority • conditioned code case: N755 (Section III) and 808 (Section XI) • currently working to finalize these priorities. Hard deadline is April 18, 2013. • Med term (under 5 years) • Specify as “B” priority • Collecting identified research gaps. Negatives resolved to go from conditionally accepted to fully accepted. • Long term (under 10 years) • Accept conditions and details into ASME code • N755 (Section III) and 808 (Section XI) • Fully accepted code case with no conditions

  7. Interconnecting Roadmap

  8. Short Term (Conditioned CC)

  9. Medium Term (Unconditioned CC)

  10. Methodology to Commonize Roadmaps: • Basic level: • Do they have the same information • Answering the questions: • What are all the issues? • Why these issue are critical? • What needs to be done for conditional endorsement and then for full endorsement? • Priorities within a group? • What issues have been resolved, what activities under way including research and what research still needs to be done? • Project timing for new activities and research?.

  11. Methodology to Track Progress: • Go through 1 line of the ASME tracking spreadsheet • Go through 1 topic of the research plans • Need to switch to Excel during presentation

  12. Concerns: • Main concerns (personal view): • Acceptance of this path forward in ASME volunteer community • Developing a champion within the community of stakeholders • Stewardship of roadmap • Fostering communication between the stakeholders and regulators • Funding those tasks that require more than code writing in the short term

  13. Stakeholders Meeting • Objective: • Educate the economic and operational case for HDPE code acceptance, • Demonstrate the current regulatory and engineering challenges for HDPE usage that have limited deployment, • Identify impact of conditional approval on market development, • Present effort to manage existing ASME and NESCC R&D priorities into one Roadmap to support short and long term design, implementation, and regulatory goals, • Gain feedback from relevant industries regarding implementation and support of this process • Attendees: Utility Operators, Plant Design and Construction, Plastic Pipe producers, NRC, ASME
