3 IDENTIFIED R&D PROGRAMS
The survey was successful in identifying solutions to many of the issues Many solutions arc currently in place or under development, such as the ongoing research by the Electric Power Research Institutc (EPRl) Others arc awaiting implcmcntation. and arc in need of rcscarch funds, such as the program outlined in a white paper jointly written by the Gas Technology Institute (GTI) and the National Instituic of Standards and Technology (NIST). entitled “Improving thc Pcrformancc of Service Water Piping in Nuclear Power Plants” Other rcsearch firms, individual researchers affiliatcd with testing laboratories or uni’.crsitics and resin manufacturers proposed solutions through testing or developing tests through experiments. These will be discusscd in the Action Plan latcr m this Roadmap.
3.1 Work In Progress
The roadmap survey revealed several issues of importance to the piping applications They are related to codes and standards, quality and performance and testing and csaluation A few of these
• CC N-7.%5-l: Split the needs and requirements of ASME Section III and Section Xl so each Section will have its own Code Casc
• U.S. and International Standards: Identify U.S. and international standards and modify where needed to reflect the requirements of HDPE in nuclear applicat.on (Aaron Forstcr. Leader)
• Define and specify design and acceptance critena. and allowable essential parameters
• Develop new, and optimize existing. test methods and procedures which deal with piping lifetime performance and prediction, based on models andor experiments.
The aforementioned issues will be further discussed later in this document.
3.2 Schedule and Key Milestones (4]
• The Roadmap strategies arc to be executed in a timely manner.
• An events schedule with key milestones will be displayed by a Gantt chart
• A justification of the events schedule with kcy milestones will be represented in tabulated form.
• The Roadmap will be a livmg document and must have a flexible approach to adapt to future considerations.
• Events schedule will include frequent peer reviews by all stakcholdcrs to ensure acceptance of the final results
• A process for rcsols ing conflicts that arise during peer rcs-iew will be provided.
