26. 26 © 2010 Electric Power Research Institute, Inc. All rights reserved. 2010-02 Digital RT Summary of Issue Currently, the industry is unable to address the evaluation and qualification of filmless radiography systems to detect planar and volumetric fabrication flaws with selected digital detector panels (DR), phosphor plates (CR), and high energy electronic radiation sources capable of penetrating the material thicknesses typically encountered in plant applications Potential Benefit of Project Expedited ASME Section III volumetric examination of piping welds with CR or DR Volumetric option/complement to UT Minimization of weld repairs with ASME Section III volumetric examination Digital storage of images instead of processed film and associated chemical processing

27. 27 © 2010 Electric Power Research Institute, Inc. All rights reserved. 2010-05 NDE Digital Data Summary of Issue Archival data is required by the Nuclear Regulatory Commission (NRC) to last for the plant's working lifetime Many utilities' document control departments will not accept digital non- destructive examination (NDE) data for archival storage and require it to be converted to a hard copy format Potential Benefit of Project This guide will assist utilities in transferring, retrieving, and archiving their NDE data and allow them a path for any future digital NDE data needs A consistent and acceptable process is needed for archiving digital NDE records, versus converting them to paper records

28. 28 © 2010 Electric Power Research Institute, Inc. All rights reserved. 2010-10 Concrete Embedded Sensors Summary of Issue Large concrete structures in nuclear power plants are typically not feasible to replace. These structures can show signs of concrete degradation by the time they go for license renewal There is a distinct need for frequent inspections of these types of concrete structures. One of the largest hindrances to concrete inspection is the lack of accessibility to many concrete structures Potential Benefit of Project Optimize inspections Better positioned for long-term asset management

29. 29 © 2010 Electric Power Research Institute, Inc. All rights reserved. 2010-11 Technical Basis for HDPE Above- Ground Use Summary of Issue There is no ASME approved code case for above-ground HDPE pipe. One has been developed for below-ground use only Several new plant designs plan on using HDPE for above-ground application Potential Benefit of Project Use of HDPE for above-ground applications will require development of appropriate design and construction rules, along with determining the engineering and material properties needed to ensure safe and reliable design and operation Critical technical issues that will be addressed include: –seismic qualification (including vents and drains) –large displacements and interactions during thermal expansion and transients –fire –structural damping values –damage during operations

30. 30 © 2010 Electric Power Research Institute, Inc. All rights reserved. 2011 Project - Cooling Tower Sourcebook for New Nuclear Plants Description Create a sourcebook to support –Design / Application –Operation –Maintenance Addressing –Natural draft –Mechanical –Dry –Hybrid

31. 31 © 2010 Electric Power Research Institute, Inc. All rights reserved. Project A – Double-walled HDPE Piping Evaluation Issue 10 CFR 20.1406, “Minimization of Contamination,” requires licensees to minimize contamination and radioactive waste generation RG 1.143 states that plastic pipe should not be used. Doubled walled HDPE is a desired option Description Review the double walled HDPE piping options available to meet the current regulations, including hardware and leak detection / monitoring options. This work would include further understanding the HDPE materials degradation properties and limitation for exposure to radioactive fluids. Work to inform a revision to RG 1.143 to acknowledge the option of using double walled plastic pipe (HDPE), with built-in leak detection capability, Value HDPE is viewed as a superior material to steel in some applications and is preferred for buried systems Providing an alternative in the RG will provide greater flexibility Cost savings on materials, installation and long term operations

32. 32 © 2010 Electric Power Research Institute, Inc. All rights reserved. Project B – EPRI Groundwater Protection Guidelines for New Nuclear Power Plants Issue The EPRI Groundwater Protection Guidelines for Nuclear Power Plants (1015118) provides technical guidance for implementing a groundwater protection program that meets the requirements of NEI 07-07. However, it currently does not provide technical guidance for implementing groundwater protection programs, namely the evaluation of plant design and operational procedures, for new plants as outlined in NEI 08-08. Description EPRI will develop an extension to the EPRI Groundwater Protection Guidelines that provides technical guidance for implementing a groundwater protection program per 10CFR20.1406, RG 4.21, and NEI 08-08. Value Understanding and preparing for any potential leaks or spills during construction will allow nuclear power plant operator to quickly identify and address any leaks or spills during operation. Timely leak detection and response will increase stakeholder confidence that utilities are protecting public and environmental health and safety.

33. 33 © 2010 Electric Power Research Institute, Inc. All rights reserved. Project F – NDE Techniques for Concrete Void Detection and Sizing Issue The main types of degradation related to concrete are the existence of honeycombs and voids due to lack of adequate concrete placement and vibration. These types of problems are related to poor design and construction, which are the leading causes of age-related degradation in concrete structures Description Voids (the focus will be on detection capabilities during the placement so that issues can be corrected immediately before curing.) Wall separation due to concrete shrinkage Damage under loadings (internal cracks, excessive stress and strain, etc...) Value Voids in concrete severely reduce the structural and shielding capacity of the concrete structure. The ability for early void detection in a nuclear construction environment will result in both financial and safety improvements. Long term asset management will also benefit from early detection and correction of construction issues with concrete structures.

34. 34 © 2010 Electric Power Research Institute, Inc. All rights reserved. Project G - URD Update Project Issue No formal process exists to maintain the URD No comprehensive listing of EPRI reports applicable to new plants exists Description Review and disposition the “Margins and Monitoring” work to ensure those recommendations are incorporated into the appropriate URD sections. Establish EPRI report reference sections for each chapter of the URD Establish a process for a) collecting input from URD users for review under a specific schedule and b) review newly issued EPRI reports and industry references for inclusion into the URD where appropriate. Value The results of the Margins work will be visible and reflected in the URD. Relevant EPRI nuclear sector reports on designing, procuring and constructing new nuclear plants will be comprehensively identified in the URD URD users will benefit from a process to ensure that their input for changes to the URD are managed in a systematic and timely manner.

35. 35 © 2010 Electric Power Research Institute, Inc. All rights reserved. Project I - QA for 2D and 3D Design and Modeling Software and V&V for Quality Software Issue The 2D and 3D design and modeling software currently being used to design and ultimately construct the next generation of nuclear power plants do not have to meet NQA-1 requirements for software and data quality. Hence, in order for these systems to be used for the operation of the nuclear power plant – a qualification of the software and data will have to occur. Description Configuration Control of the Data in Engineering Applications that will have Plant Life Cycle use Quality Control of the 2D / 3D design and modeling software and other associated databases and software in a commercial grade dedication method prescribed by NQA-1 Value An industry standard approach to software and data quality for the 2D and 3D design and modeling software and other associated databases and software.

36. 36 © 2010 Electric Power Research Institute, Inc. All rights reserved. Project R – High Strength Rebar use in Nuclear Power Plants Issue The use of higher strength rebar in the design and construction of safety related concrete structures and / or containment structures could result in cost savings for new nuclear power plants by reducing the quantity of rebar required. Cost savings would result from reduced rebar material purchase costs and reduced construction cost due to reduction in the quantity of rebar placed Description Develop and implement a concrete testing program to support adoption of higher strength rebar use in ACI 349 and ACI 359. Involve the NRC to facilitate endorsement of the higher strength rebar in a future revision of Reg. Guide 1.142. Value The use of High Strength Rebar in the general construction industry has made high strength concrete in seismic zones cheaper and easier to construct due to the lower density of rebar in structures. High Strength Rebar has greater resistance to corrosion over convention rebar, providing a potential longer life in nuclear plant application.
